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 highly 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-inch rack was limited 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.
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
This interface is Matsusada Precision's proprietary dedicated digital communication port. This interface has modular type IN and OUT ports to allow daisy-chain connection. Combined with an adapter (sold separately). Multiple power supplies can be controlled at once. Adapters for LAN, USB, RS-232C, RS-485, and GPIB are available so that you can choose a suitable communication interface. One-control operation by master/slave connection is also possible. * Not a function for increasing current by parallel connections.
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.
