COMPACT DC ELECTRONIC LOAD

  • Load Voltage: 18V 36V 60V
  • Load Current: 2A 5A 10A
  • Load Power: 75W
  • Extremely compact

75W Load in ultra-compact 1.38-inch width

No need big testing space. EGS series, the compact DC electronic load, is perfect for testing small batteries, power supply circuits, etc. The EGS series features a compact, lightweight design and high-efficient control modes that contribute to a space-saving and intelligent system.

Features

  • Capable of batch control of maximum of 16units with the master/slave function
  • Setting in 1mA increments depending on the models.
  • Multiple operation models of Constant Current (CC), Constant Resistance (CR), Constant Voltage (CV), and Constant Current + Constant Voltage (CC + CV)

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

While the number of units installed on a 19 inches 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.

A maximum of ten units are available on a 19 inches 3U-size rack. | EGS series | DC Electronic Loads | Matsusada Precision

Batch control of up to 16 units with the master/slave function

EGS series is available for multi-channel DC electronic load.

Master/Slave Control
The operations of multiple EGS devices can be controlled from the master device. Up to 16 units can be connected.
The connection of master/slave control will be made between the same models.

Functions

Digital Interface

The unified control is available with master/slave operation along with USB/LAN/RS-232C/RS-485/GPIB in digital control.
To use the digital interface, you need to prepare an digital interface adapter separately.

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.

Options

-LCcv

Constant current (CC) mode + Constant voltage (CV) mode, and Undercurrent protection (UCP) are available for this option.

-LH

The ground voltage between the load connection terminals and chassis is ±500 Vdc.

-LUs1

Enable digital control with USB
One power supply can be connected per one USB port which the computer equipped.
In case the number of USB ports of the computer is not enough, use USB HUB.
However, it may not work correctly, depending on USB HUB.
* It is not available with the Master/Slave function.
