1. GPE48150G System Configuration

The system consists of distribution unit, rectifier module (1 min.,5 set max.) and monitoring module. The configuration is optional, as following table:

2. Operating Principle

AC mains is first input AC-INPUT MCB and then fed into the rectifier module after the SPD and EMI filtering. AC-INPUT acts as protection to over load and short circuit to AC power. The LOAD1-,LOAD2-,LOAD3-,LOAD4-,LOAD5- link in series to 2 power-off contactors KM1,KM2.The user’s battery is connected to the DC output side through MCB BAT and KM2, and the MCB provides disconnection control, over-load and short-circuit protection to the battery.

Under normal conditions, every parameter of rectifier modules and distribution unit are controlled by the monitoring module, operating according to the pre-set parameter or user’s commands. If AC mains fault, the battery will power to the system. With the battery discharge, the terminal voltage of the battery starts to descend. When the voltage is under -47V±0.5V, the monitor reports DC under voltage alarm signal and when the voltage is under -46.0V±0.5V (adjustable), the KM1cuts off LOAD3-,LOAD4-,LOAD5- and retaining power to LOAD1-,LOAD2-. If the voltage drops to -43.0V±0.5V (adjustable), the KM2 will cut off output of LOAD1-,LOAD2- and then the power system will stop working. If the external AC mains recovers, the system will normally work again. (All above monitoring data are system default values and can be reset by user).
Except for battery over-discharge protection, battery or load over-temperature protection is prohibitive under default setting, users can send command to activate or inactivate according to the demanding. To avoid the thunder and thunder surge pulse current break the power system, and match to the thunder protection module ideally, we must load decoupler on output port independently or keep some length cable.
