Battery Load Bank

1.       Overview：

l  The battery Load Bank as discharge monitor is specially designed for the battery string for verification discharge experiments, capacity tests, and daily maintenance of battery strings, engineering acceptance and other tests of DC power supply load capacity. Using the latest wireless communication technology, the battery discharge process can be monitored in real time through the PC monitoring software, and the discharge process of each battery can be monitored.

l  The power consumption part of the tester adopts the new PTC ceramic resistor as the discharge load, which completely avoids the red hot phenomenon, and is safe and reliable without pollution. The whole machine is controlled by a microprocessor, LCD display, and English menu. The design is novel, small in size, light in weight and easy to move. After the various discharge parameters are set, the entire constant current discharge process is automatically completed. Fully intelligent. Make the entire discharge process safer.

l  The portable and intelligent professional design of the tester series makes the discharge test work simple and easy, greatly reduces the labor intensity of professional maintenance personnel, and also improves the scientific and intelligent discharge test.

2.       Functions description

Function 1: Check-in discharge
