Power Supplies

What are Power Supplies?

A power supply is a device that supplies electrical energy to an electrical load. It converts one form of electrical energy to another, such as converting AC (alternating current) to DC (direct current). Power supplies are used in a variety of electronic devices, from computers and cell phones to TVs and gaming consoles.

What Do We Supply?

We supply an extensive range of power supplies, including:
External Power Supplies
Battery Chargers
DC/DC Converters
LED Drivers
Internal Power Supplies (DIN rail, Enclosed, PCB Mount, Open Frame, U Frame)

Where we can, we will ensure you get next day delivery on your product order, and we are also happy to discuss flexible payment terms if that will help.

Crouzet AC Synchronous and DC Stepper Motors for All Needs

AC Synchronous Motors

AC Synchronous Motors are the best solution for applications that require constant movement and a low torque, like in in medical equipment, valves, pumps and water treatment. Their rotation speed is directly proportional to the supply frequency, that means it’s always constant and independent from the load.

DC Stepper Motors

DC Stepper Motors are a great choice for simple applications that require long durability and easy integration, like small HVAC systems, photocopy machines, plot-ters, medical pumps and drip feeders, or vending and gaming machines.

Gearboxes

To meet the perfect speed and torque levels for the great majority of applications, we offer a complete range of gearboxes, with a wide variety of ratios, for adjusting our motors.

Each gearbox has been designed for a specific workload and optimized for a long mechanical life, with a big capacity to absorb the maximum torque in continus movement.
