Made of durable components for a long life in demanding conditions, these power supplies convert AC voltage to power DC motors and other devices that require high start-up current. They briefly boost power above their maximum output, which means you don't have to use an oversized power supply just to handle occasional spikes. Mount them onto DIN rails in marine, heavy industrial, and other tough environments. Power supplies with spring-clamp terminals connect quicker and hold firmer than screw-style terminals.

Because they're made to the highest quality standards, you can rely on these power supplies to run critical automation and process control systems. They maintain a stable output, even in facilities with electrical noise, voltage fluctuation, or poor power quality. Compared to standard power supplies, they require less start-up current, which further improves stability. All 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, temperature, 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 SELV (separated extra low voltage) or PELV (protected extra low voltage) circuits.

Rated IP20, these power supplies prevent your fingers from touching internal components and accidentally shocking yourself. 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 and ABS.

Supplies that have a Class I, Division 2 environmental rating are safe for use in environments that are not normally hazardous, but where concentrations of combustible gases may occur infrequently. Some power supplies have ATEX and IECEx certifications, which are international ratings for hazardous environments.

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 voltage signal send a signal that indicates the status of their output voltage, so you know if your power supply isn't working correctly. Configure them to light up a panel or activate an alarm when voltage drops, or connect them to a PLC for remote system monitoring.
