Less than 3" 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.

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 your power supply exceeds the maximum voltage or load, these power supplies protect both the power supply and the connected equipment. Some also protect against excessive temperatures. All meet the voltage requirements for use in a SELV (separated extra low voltage) circuit.

Rated IP20, these power supplies prevent your fingers from touching internal components and accidentally shocking yourself. They have also passed strict U.S., Canadian, and European Union safety standards.

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. These power supplies cannot be sold to the regions listed due to local energy efficiency requirements.

Power multiple devices with different voltages at the same time. These power supplies convert AC to DC voltage or step down high DC voltages to low DC voltages. Mount them to the DIN rails inside industrial cabinets and electrical panels, or unscrew the DIN clips to mount to any flat surface.

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 temperature or load, these power supplies shut down to protect both the power supply and the connected equipment.

Rated IP20, they are designed to stop your fingers from touching internal components, which prevents accidental shocks. All are CE Marked, UL recognized, and C-UL recognized, meaning they meet European, U.S., and Canadian safety standards. They have been safety tested for both AC and DC voltage inputs. They also meet specifications for UL 94 V-0, so they will self-extinguish within ten seconds if they catch fire, and won’t cause additional fires by dripping.

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.

Power factor shows how effectively a power supply draws AC power from the main electrical supply. The higher the power factor—up to a maximum score of 1—the lower your operating cost.

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.

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.

If you exceed the maximum current, load, or voltage, these power supplies shut down to protect both the power supply and the connected equipment. All meet stringent safety standards.

Power supplies that cannot be sold to the regions listed are restricted by local energy efficiency requirements.

Convert AC voltage to clean, predictable DC voltage for powering highly sensitive devices, such as measuring, testing, and audio equipment. These power supplies keep electronic interference (also known as output noise or ripple noise) from being passed on to your device.

Although they create less noise than switching power supplies, these power supplies are larger, heavier, and give off more heat. Their efficiency rating is also lower than switching power supplies, which means more energy is lost while they convert AC to DC power. The lower the efficiency rating, the higher your operating costs.

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. As they send power to a device, they use remote voltage sensing to check for any drops in the voltage. If the voltage dips, they can compensate with extra power, so connected devices always receive the correct voltage. They cannot be sold to California and Vermont due to local energy efficiency requirements.

All of these power supplies 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.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%.

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.

When your power supply sends out DC power at a higher voltage than you need, change to the proper voltage with these converters. They’re often used when a specific component, such as a sensor, requires a lower voltage than surrounding equipment. Use them to correct power supplies that send uneven voltages, too—they provide electricity at a stable, consistent voltage. They mount on flat surfaces, and are commonly fastened inside enclosures.

If you exceed the current limit, these converters will shut down to protect your equipment. Some converters have overvoltage protection, so they’ll do the same if you exceed voltage limits.

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.
