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.
