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)

E-T-A Power Entry Modules

Power Entry Modules with Integrated Circuit Breakers

Systematically reducing components is a major success factor for a cost-saving design. And what is more: Fewer components increase the overall reliability and usually lead to space-savings.

E-T-A’s power entry modules combine up to five functions in a single component: a C14/C20 appliance inlet, resettable overcurrent protection, an ON/OFF switch, a line filter and an optional undervoltage release, remote trip or auxiliary switch.

Compared to standard connector modules with fuses the E-T-A power entry modules are equipped with resettable circuit breakers. After an overcurrent trip they can be reset quickly, reliably and easily. Time-consuming fuse replacement is eliminated. Thanks to screw mounting, E-T-A power entry modules have a firm and robust fit in the housing and can thus withstand even high pull-out forces of power cables without any problems.

Benefits:

  • Reduced assembly and wiring effort (up to 90 %!)
  • Reduced material planning and stock keeping costs
  • Increased equipment uptime: Quickly and easily reset circuit breakers
  • Time-consuming fuse replacement is omitted
  • Low operational costs: No expenses for procurement, inventory management and service for fuses
  • High safety: multipole circuit breakers reliably interrupt the current-carrying phase conductor in the event of a fault. This prevents electric shocks.
