Programmable DC Electronic Load
- Maximun Voltage: 18V to 60V
- Maximum Current: 2A or 10A
- Maximum Power: 75W
- Extremely compact
Load 75W in an ultra-slim width 35mm
In conducting evaluation tests of small systems like batteries or power supply circuits, you will consider a load device in a compact design.
Features
- Capable of batch control of maximum of 16units with the master/slave function
- Model lineup with output current control by a 1mA unit available
- Performed in four modes of Constant current, Constant resistance, Constant voltage, and Constant current + Constant voltage
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.
* Please refer to the "RMO series" brochure for details of the dedicated adapter.
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.
Providing four operating modes
- 1 Constant current (CC) mode
- 2 Constant resistance (CR) mode
- 3 Constant voltage (CV) mode
- 4 Constant current (CC) mode + Constant voltage (CV) mode *Available for -LCcv option

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.
External Output ON/OFF
Specifications
Options

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.
