For critical systems, demanding environments, and any application where downtime is not an option, these reliable power supplies convert AC to DC voltage to keep power flowing. They mount onto DIN rails, which are usually found inside electrical panels and cabinets. Made with the highest-quality internal components, they're designed to last in marine, heavy industrial, and other tough environments. Power supplies with spring-clamp terminals connect quicker and hold firmer than screw-style terminals.

These power supplies 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.

For many of these power supplies, exceeding the maximum voltage, temperature, or load will cause the power supply to shut down to protect both the power supply and the connected equipment. Some power supplies meet the voltage requirements for use in a PELV (protected extra low voltage) circuit; some also meet the requirements for use in SELV (separated 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 Rheinland certification, these power supplies meet stringent safety standards. Some meet additional standards for marine vessels classed by DNV-GL and Lloyd's Register.

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.
