Electrical Transforming and Conditioning

Ultra-Low-Noise Power Supplies

Often used for high-precision and sensitive electronics such as testing and audio equipment, these power supplies produce low output noise for minimal electronic interference.

Touch-Safe High-Inrush
Panel-Mount AC to AC Transformers

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.

Harsh Environment High-Inrush
Panel-Mount AC to AC Transformers

Sealed coils protect against dust, dirt, oil, and moisture. These transformers can handle momentary high-inrush current associated with contactors, solenoids, and relays.

High-Inrush Panel-Mount AC to AC Transformers

These transformers can handle momentary high-inrush current associated with contactors, solenoids, and relays.

Enclosed Isolating AC to AC Transformers

These transformers have isolated primary and secondary coils to protect your sensitive equipment from input voltage spikes.

Enclosed Voltage-Stabilizing AC to AC Transformers

Protect equipment from electromagnetic interference and maintain power during three-millisecond power dips.

Outlet Box/Panel-Mount
High-Inrush AC to AC Transformers

Use the included mounting plate to mount these transformers to a panel. They can handle momentary high-inrush current associated with equipment start-up.

Low-Current AC to AC Transformers

Power low-voltage devices such as alarms and sensors.

Low-Current Panel-Mount AC to AC Transformers

Hardwire this transformer into your panel.

Panel-Mount Variable-Voltage
AC to AC Transformers

Permanently install these transformers in panels.

Bench-Top Variable-Voltage AC to AC Transformers

Mount these portable transformers to any flat surface.

AC to DC Electromagnet Transformers

Flip the switch to reverse the magnetic current and release your electromagnet's hold.

High-Speed AC to DC Electromagnet Transformers

Suitable for high-speed automated applications, these transformers reverse the magnetic current and release your electromagnet's hold faster than other electromagnet transformers.

Backup Power Supplies

Transfer power to a built-in battery during brownouts and blackouts with only a momentary loss of power during transfer.

Low-Profile Power Conditioning
Backup Power Supplies

Smaller in height than standard backup power supplies, these fit in tight spaces.

Power Conditioning Backup Power Supplies

Prevent damage to sensitive equipment—these conditioners raise or lower current to keep it at a normal level during dips and surges.

Electrical Testing Power Supplies

Ultra-Low Noise Benchtop Power Supplies

Change AC voltage to DC voltage to power extremely sensitive audio, measuring, and testing devices while keeping electronic interference—often called output or ripple noise—from passing on to the device.

Benchtop Power Supplies

Convert AC voltage into the DC voltages needed to test, design, and prototype a wide variety of electrical circuits and equipment.

Programmable Benchtop Power Supplies

Use your computer to remotely control these power supplies that convert AC voltage to DC voltage for powering electronics from simple prototypes to advanced testing equipment.
