Completely sealed and protected from dust and water, these power supplies don't need a separate electrical panel or enclosure. Instead, mount them directly to machine tools, process control equipment, conveyors, and other equipment found in harsh industrial areas. They convert AC voltage to deliver DC power right at the point of need, reducing the need for complex wiring.

Rated IP67, all of these power supplies are safe for use in dusty, humid, and wet locations, as well as in applications where the power supply may be briefly submerged in water. IP66-rated power supplies can also withstand frequent washdowns. IP68-rated power supplies are safe for use outdoors as well as under water for extended periods. They're tested to withstand submersion in 1 meter of water for 40 days.

Although sealed in a housing, these power supplies have excellent heat dissipation, so they run reliably even as temperatures rise. They 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 create much heat. Some of these power supplies are also SEMI F47 compliant, which means they meet standards for maintaining output voltage when input voltage dips. This is commonly known as voltage sag immunity.

If you exceed the maximum voltage 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 a SELV (separated extra low voltage) circuit. With various domestic and international certifications, such as UL listing and CE marking, you can be sure 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.

Power supplies with an output peak current briefly boost power above their maximum operating current for starting motors, actuating solenoid valves, and other applications that require a higher starting current than their operating current.

Power supplies that cannot be sold to California and Vermont do not meet energy efficiency requirements.

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 Components, TUV Rheinland 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.

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.

Convert AC to DC voltage to power equipment in tight spaces—since these power supplies don’t have an enclosure, you can use them inside devices where enclosed power supplies can’t fit. The open construction lets heat out, so they also run cooler than standard power supplies with the same output. However, since they are not enclosed, these power supplies can shock you if you touch their components. They are best for devices with sealed housings, and should not be used in enclosures that are opened frequently.

Reliable

These 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.

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.

Energy Efficient

The combination of power factor and efficiency gives you a sense for how efficiently these 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 your power supply, the cooler it runs too.

Safe

These power supplies meet U.S. and international safety standards. If you exceed the maximum current, load, or voltage, they’ll shut down to protect both the power supply and the connected equipment.

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.
