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.

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. In addition to sending a signal, if you exceed the maximum current, load, voltage, or temperature, these power supplies shut down to protect both the power supply and the connected equipment.

They're UL and C-UL recognized, TUV certified, and CE marked so you know they meet stringent 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.

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.

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.

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 94V0, 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.

Convert 120V AC to six common DC voltages with these power supplies. They’re often used for simple, low-power tests on electrical circuits and devices, as well as for prototyping. Plug your equipment into the output sockets with banana plugs, and slide the selector switch to choose the voltage.

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. It also means they won’t get too hot.
