EGS series

Ultra-Compact DC Electronic Load

  • Operating Voltage: 0.3V to 60V
  • Max Current: 2A or 5A
  • Maximum Powor: 75W
  • Extremely compact

Ultra-thin 35mm-width for space saving and light weight

In conducting evaluation tests of small systems like batteries or power supply circuits, you will consider load device in a compact design.

Features

Perfect space saving with an extremely compact, lightweight body to suit any customers' space for installation

While the number of units installed on a 19-inch rack was limited up to about only five as multiple units so far, the EGS units can accept as many as 10 units in even smaller spaces than usual.

EGS Series, Digital Interface

Master/Slave Control

The operations of multiple EGS devices can be controlled from the master device. Up to 16 units can be connected.

* Not a function for increasing current by parallel connections.

(A) CO-M Cable

As of models without interface option, a two-meter cable is provided in each unit. If you need a longer cable or additional cables, please consult with our sales staff.

The connection of master / slave control will be made between the same models.

Use GP-M cable

Load-Off Timer Function

As the load-off timer function is set through the front panel operation, the elapsed time monitoring starting load-on as well as the automatic load-off are available in a certain period of time. Time can be set from 1 second to 999 hours, 59 minutes, 59 seconds.
