Sized to fit into small and cramped enclosures, these compact power supplies mount onto DIN rails to convert AC to DC voltage. Despite their size, they're designed to power motors, solenoid valves, and other devices that require large start-up current. To do so, they briefly boost power above their maximum output current. This means you don't have to use an oversized power supply just to handle occasional spikes in demand.

All of these power supplies use switching regulation, which means they produce the stated voltage despite fluctuations in your input power and the power being drawn by your system, and they won’t become too hot.

If you exceed the maximum voltage, current, or load, these power supplies shut down to protect both the power supply and the connected equipment. They also meet the voltage requirements for use in an SELV (separated extra low voltage) circuit.

Rated IP20, these power supplies prevent your fingers from touching internal components and accidentally shocking yourself. They're UL and C-UL certified and CE marked so you know they meet stringent safety standards. With Class I, Division 2, Groups A, B, C, and D environmental ratings, all are safe for use in environments that are not normally hazardous, but where concentrations of combustible gases may occur infrequently.

Maximum output noise is also known as ripple noise. The lower the value, the less interference the power supply creates. For most applications, a value over 100mVpp isn’t a problem. However, when using to power extremely sensitive electronics, such as audio equipment and high- precision measuring and testing equipment, you’ll want an output noise around 5mVpp or less.

Efficiency describes how good a power supply is at converting the AC power it draws from your main electrical supply into DC power. High-efficiency power supplies cost less money to operate and produce less heat, meaning cooler temperatures in your electrical cabinet.

Power supplies cannot be sold to California or Vermont due to energy efficiency requirements.

Less than 2 1/2" deep, mount these power supplies to a DIN rail in shallow enclosures and control panels, such as those used in building automation systems. They briefly boost power above their maximum operating current to start motors, actuate solenoid valves, and other applications that require a higher starting current than their operating current. All of this means you get a more powerful power supply in a compact size.

To power electronics ranging from simple prototypes to complex industrial automation and process control equipment, these general purpose power supplies convert AC to DC voltage. Mount them to a surface inside your device’s enclosure.

So you don’t accidentally touch internal components and shock yourself, these power supplies have their own housing. If you occasionally need to poke around inside your device’s enclosure, the housing also protects the power supplies themselves from damage. But compared to open-frame power supplies, these have a larger footprint, so they won’t fit in tight spaces.

For output wire connections, choose from standard screw terminals, screw-clamp terminals, and tab terminals. Use tab terminals if you have wires with ring terminal ends. To connect them, slide a screw through the hole in the tab terminal, slip the ring terminal from your wire over the screw, and tighten a nut on the end of the screw to hold everything in place. Screws, nuts, and ring terminals are not included.

All of these power supplies use switching regulation, which means they produce the stated voltage despite fluctuations in your input power and the power being drawn by your system, and they won’t become too hot. Power supplies that are SEMI F47 compliant meet standards for maintaining output voltage when input voltage dips. This is commonly known as voltage sag immunity.

Often used for high-precision and sensitive electronics such as testing and audio equipment, these power supplies produce low output noise for minimal electronic interference. They are designed with linear voltage regulation, so they deliver the same voltage regardless of changes in the input voltage or current. These power supplies also have remote voltage sensing—when voltage dips they compensate with extra power, so your devices always receive the correct voltage. However, they give off more heat, weigh more, have a larger footprint, and lower efficiencies than switching power supplies. Mount them on the inside surface of device enclosures.

All meet U.S., Canadian, and European safety standards. If you exceed the maximum load or current, they shut down to protect both the power supply and the connected equipment. These power supplies cannot be sold to the listed areas due to local energy efficiency requirements.

Power supplies with overvoltage protection will shut down if you exceed the maximum voltage.

Covers keep you from accidentally touching the power supply interior, protecting you from shocks. However, these covers reduce the power supply’s maximum output by 15%.

Save power by switching these power supplies on and off remotely, so devices only run when they're needed. Use them to convert AC voltage to DC to power electronic equipment ranging from simple prototypes to complex industrial automation and process control equipment. Mount them to a surface inside your device’s enclosure.

Besides turning them on and off, these power supplies have two other remote capabilities. Remote voltage sensing lets them compensate for any voltage that’s lost as it travels across the wires, ensuring that devices get the correct voltage. They also send a signal if the voltage drops, the cooling fan fails, or they exceed the maximum current, load, voltage, or temperature.

To use the remote features of these power supplies, you’ll need a wire connector (sold separately). Eight pin connectors enable remote on/off, voltage sensing, and signaling functionality using the power supply’s auxiliary power output. Ten pin connectors only add remote on/off and voltage sensing functionality. They require an external power source, such as a battery or another power supply.

So you don’t accidentally touch internal components and shock yourself, these power supplies have their own housing. They're good to use in spots where you occasionally need to access the inside of your device’s enclosure, since the housing also protects the power supplies themselves.

For output wire connections, they have either standard screw terminals or tab terminals. Choose tab terminals if you have wires with ring terminal ends. To connect them, slide a screw through the hole in the tab terminal, slip the ring terminal from your wire over the screw, and tighten a nut on the end of the screw to hold everything in place. Screws, nuts, and ring terminals are not included.

Mount these DC converters to DIN rails on fixtures such as industrial cabinets and electrical panels. By converting voltages, they let you connect power supplies to equipment that requires a different input voltage. They’re often used to power sensors or other components that require a lower voltage than surrounding equipment. Since they send a stable, consistent voltage to equipment, they can also be used to correct power supplies that send uneven voltages. All meet U.S. and Canadian, or European Union, safety standards.

If you exceed current limits, these converters will shut down to protect your equipment. Some converters have overvoltage or overload protection, as well.

The lower a converter’s maximum output noise, also known as ripple noise, the less electronic interference it creates. These converters will work in most applications.

Change AC voltage to DC voltage to power extremely sensitive audio, measuring, and testing devices while keeping electronic interference—often called output or ripple noise—from passing on to the device. The lower the output noise value, the less interference the power supplies will create. Although they create less noise than other power supplies, these power supplies are larger, heavier, and give off more heat.

Designed with linear voltage regulation, these power supplies produce the same voltage regardless of changes in the input voltage or the amount of current being drawn. They are also known as linear power supplies.

View the output on a digital or analog display. Digital displays are often easier to read than analog displays, so you can quickly see if you need to make adjustments.

If you exceed the maximum load or current, all of these power supplies will shut down to protect both the power supply and the connected device. Those with overvoltage or over temperature protection will shut down if you exceed the maximum voltage or temperature.

Power supplies that cannot be sold to California and Vermont are restricted by local energy efficiency requirements.

Convert AC voltage into the DC voltages needed to test, design, and prototype a wide variety of electrical circuits and equipment. These power supplies let you adjust the output to the exact voltage needed to power your equipment. You can also set limits on the maximum current to protect your equipment from damage. Keep an eye on the voltage and current drawn by your connected components with the digital display.

Since these use switching regulation, they produce the stated voltage despite fluctuations in your input power and the power being drawn by your system, and won’t become too hot.

When these power supplies convert AC voltage to DC voltage, some noise from the AC voltage will carry into the output. While this won't affect most applications, this noise can interfere with other signals in extremely sensitive applications. The lower the output noise, the less interference it creates.

These power supplies are CE Marked, which means they meet European Union safety standards. If your power supply exceeds the maximum current, voltage, or load, they’ll shut down to protect both the power supply and the connected equipment. Some also protect against excessive temperatures.

Connect the banana plugs on your equipment to the socket output connections. Power supplies with USB-A output connections can also charge phones and other devices with USB-A ports. You can use more than one output at the same time, but you can’t adjust them independently—all outputs are set to the voltage you select.

Power supplies that cannot be sold to California and Vermont are restricted by local energy efficency regulations.

Change AC voltage to DC voltage and bring power to electronic devices while protecting them from harmful electromagnetic interference (EMI). Even with their built-in power supply, these connectors have the same overall footprint as those without a power supply. All are for use with standard IEC power cords. Commonly used to convey power from wall outlets, you won’t have to wire your devices to an external power source. Instead, wire these connectors into your device with the terminals on the back of each connector.

For fast wire connections, these connectors have quick-disconnect terminals. The terminals slide together with the quick-disconnect terminals on your wiring and are easily disconnected by hand, but still provide a strong hold.

All of these connectors use switching regulation, which means they produce the stated voltage despite fluctuations in your input power and the power being drawn by your system, and they won’t become too hot. If you exceed the maximum voltage or load, the connectors will shut down to protect both the power supply and the connected device. They also meet the voltage requirements for use in a SELV (separated extra low voltage) circuit.

These connectors meet U.S. and international standards for safety. They also meet UL 94 V-0, which means they self-extinguish within 10 seconds if they catch fire, and won’t spread the fire by dripping. All have Class I shock protection—they're insulated and have a protective ground to prevent electrical shocks.

Maximum output noise is also known as ripple noise. When power supplies convert AC voltage to DC voltage, some noise from the AC voltage will carry into the output. While this noise won't affect most applications, it can interfere with other signals in extremely sensitive audio equipment and high-precision measuring and testing equipment. The lower the output noise, the less interference it creates.

Power factor and efficiency give you a sense for how efficiently these connectors draw AC power and convert it into DC power, which ultimately affects your operating cost. The closer the power factor is to 1, and the higher the efficiency percentage, the lower the operating cost. The more efficient the power supply, the cooler it runs.
