EGD series

Desktop size DC Electronic Loads

  • Operational Voltage range:
    1.5 Vdc to 150Vdc
  • Max. Current: 30A to 60A
  • Max. Power:
    150W, 200W, and 300W
  • World wide input

Compact Size and High Power

EGD series are best-fitted DC electronic loads to life tests for batteries or DC power supplies, aging test and so on. They are able to build the charge and discharge system combined with our DC power supplies REK series or RK series with LAN, USB, RS-232C, RS-485, or GPIB interface.

Features and Benefits

  • Five units can be placed into a 19 inches Rack of 3U size. (150 W and 200 W models)
  • They are operable in two modes of Constant Current (CC) and Constant Resistance (CR).
  • World wide input is applicable to any commercial electric power sources in the world.
  • Package control to 16 units is possible.

Functions

EGD series is light and compact!

Maximum load capacity 200W is realized

At the evaluation test of compact battery which is not so much large, we also hope to place the load device compactly.
EGD series are just fitted the best electronic load for such situation.
They can be utilized in Stand-Alone with operation on the front panel.

Weight: approx 3.6 kg
