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.

Power supplies with an NEC Class 2 output limit the risk of electrical shock should something fail inside the power supply.

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. All of this means you get a more powerful power supply in a compact size.

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.

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.

Power supplies cannot be sold to California or Vermont due to energy efficiency requirements.

To power electronics ranging from simple prototypes to complex industrial automation and process control equipment, these general purpose power supplies convert AC to DC voltage. Mount them to a surface inside your device’s enclosure.

So you don’t accidentally touch internal components and shock yourself, these power supplies have their own housing. If you occasionally need to poke around inside your device’s enclosure, the housing also protects the power supplies themselves from damage. But compared to open-frame power supplies, these have a larger footprint, so they won’t fit in tight spaces.

For output wire connections, choose from standard screw terminals, screw-clamp terminals, and tab terminals. Use 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.

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.
