Battery Load Unit

Model: FD-840

Battery Load Unit FD-840 is used to do discharge test of 12V, 24V, 48V, 96V/110V or 220V/240V battery banks in substations. The voltage changes of single cells also can be monitored via Bluetooth module during test. The users can view various parameters and curves of single cells and battery banks in powerful PC analysis software.

Main Features

1) 7-inch touch screen for easy operation

2) Wider test voltage range for different battery banks

3) Support three discharge modes: constant current, constant resistance, constant power

4) Able to calculate the discharge current automatically

5) Able to monitor and display real-time voltage change of battery cell

6) Bluetooth wireless module for monitoring sing cell

7) Test results can be saved on-board or into SD card

8) PC analysis software for viewing various parameters and curves of battery and generating test reports
