- Load power:
150W, 200W, and 300W - World wide input
COMPACT AND HIGH POWER PROGRAMMABLE DC ELECTRONIC LOADS
EGD series is ideal for DC electronic loads for testing batteries, power supplies and power converters, 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
- 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).
- Worldwide input is applicable to any commercial electric power source in the world.
- Package control to 16 units is possible.
APPLICATIONS
- Evaluation of switching power supply
- Evaluation of DC/DC converter

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 a situation.
They can be utilized in Stand-Alone with operation on the front panel.
Weight: approx 3.6 kg
They can be utilized as DC electronic load of multi-channels
If the dedicated adapter (Sold separately) is used, a maximum of Five units of EGD series are placed in a rack of 19 inches and they can be utilized as a DC electronic load with multi-channel.
Following combination is able.
