The equipment is based on special DC bus-bar patent technology which is taking IGBT as main circuit, it can directly make use of the discharging energy through rational charging/discharging action among several equipment. GH type specialized on DC bus-bar recovery, while GHA type specialized on energy recovery, it can make unwanted electricity back to AC grid, so GHA type has a more obvious energy-saving effect. With microprocessor-controlled HF charging/discharging technology, each circuit is controlled by a microprocessor, which having reliable, easy-operated and self-inspected functions, as well as low harmonic pollution, high power factor and stable output DC current. Functions:

Setting and storing many formation modes and parameters of different types of battery. Providing the following operation modes: constant-current charging, constant-voltage charging, constant voltage with current-limited charging, constant-current with voltage-limited discharging, cycling and pause; State shifting by time setting/voltage setting/Ah setting, recording operation data at setting time; Protecting against overcurrent, overvoltage and open circuit. Power off data logging, and automatic power on recovering; Protecting against battery anti-connection, over-discharging and output short circuit, and providing power off protection; Displaying on LED operation data and cause of troubles. Central network control and data processing when connected with PC via interface.
