Convert AC voltage to power DC motors, solenoid valves, charging capacitors, and other devices that require large start-up current. These power supplies mount onto DIN rails and are capable of briefly boosting power above their maximum output. It means you don't have to use an oversized power supply just to handle spikes in demand. With a set of standard features, they're a cost-effective way to power motors in clean, controlled environments that have a stable supply of electricity. They're not recommended for tough industrial environments.

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. Some are also SEMI F47 compliant, meaning 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, current, or load, these power supplies shut down to protect both the power supply and the connected equipment. Some also meet the voltage requirements for use in an SELV (separated extra low voltage) circuit.

With various domestic and international certifications, such as UL listing, CE marking, and TUV certification, these power supplies meet stringent safety standards. Some meet additional standards for marine vessels classed by DNV-GL. Power supplies with an IP20 rating prevent your fingers from touching internal components and accidentally shocking yourself.

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.
