Isolating Transformers | McMaster-Carr

Prevent accidental contact with live electrical connections—the screw terminals are covered or recessed. These transformers can handle momentary high-inrush current associated with contactors, solenoids, and relays.

Heavy Duty Motor-Starting DIN-Rail Power Supplies

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.

Motor-Starting DIN-Rail Power Supplies

Convert AC voltage to power DC motors, solenoid valves, charging capacitors, and other devices that require large start-up current.

Compact Motor-Starting DIN-Rail Power Supplies

Sized to fit into small and cramped enclosures, these compact power supplies mount onto DIN rails to convert AC to DC voltage. Despite their size, they're designed to power motors, solenoid valves, and other devices that require large start-up current.

AS-Interface DIN-Rail Power Supplies

Send both electrical and data signals to equipment on AS-interface networks.

Low-Profile DIN-Rail Power Supplies

Less than 2 1/2" deep, mount these power supplies to a DIN rail in shallow enclosures and control panels, such as those used in building automation systems.

Status-Indicating DIN-Rail Power Supplies

Monitor voltage, current, remaining life, and other maintenance data from your PC, PLC, or by glancing at the digital display. There's no need to inspect these power supplies with multimeters or other test equipment.

Open-Frame Power Supplies

Convert AC to DC voltage to power equipment in tight spaces—since these power supplies don’t have an enclosure, you can use them inside devices where enclosed power supplies can’t fit.

Sealed Power Supplies

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.

Power Supplies for Programmable Logic Controllers

Designed for PLCs, these power supplies attach to your processor to bring your automated system to life. Once connected, they take in the voltage from your facility, convert and regulate it, and send out stabilized power to the rest of your equipment.
