Summary：

This product developed according to the latest requirements of lead acid battery users in China and abroad, using microcomputer control insulation gate bipolar transistor (IGBT) DC-DC technology, a microcomputer control the power supply of each circuit, each circuit work independently, the same system circuit share a set of dc bus, circuit charging from the bus, circuit discharge to the bus feedback power.

This equipment supports manual and fully automatic operation. Users can compile various formation and charging and discharging processes in the computer, and send them to the designated circuit, or compile various processes through the control panel of each circuit. Each loop can be independently controlled and operated according to the user's process, and the whole operation process can be completed automatically. High reliability, easy to operate, fault self-diagnosis, small harmonic pollution to the power grid, high power factor, high output DC current accuracy. Each equipment loop has one temperature measurement point, the user can set the upper limit and lower limit temperature, the equipment beyond the temperature range can realize automatic shutdown and report the over temperature fault.

Function：

The charge and discharge loop is uniformly managed by the control computer through the communication bus, and the equipment is fully automatically operated, which can realize the centralized network control and data processing of multiple power sources. To achieve unattended, remote monitoring.

Users can program the formation process and parameters of all kinds of batteries, with the working modes of constant current charging, constant voltage charging, constant current limiting charging, constant current limiting voltage discharge, circulation, static setting, clearance pulse, etc., with the stage conversion mode of fixed time, fixed voltage and fixed current, and the function of timing recording and printing operation data.

Complete protection functions: with protection functions such as over current, over voltage, voltage lack, current cut and power loss data storage, and automatic recovery of power call; with protection functions such as battery reverse connection, over discharge, output short circuit fire protection, and display current operation data and fault causes through LED and computer.
