Configuration Rectifier Module Monitoring Module Power Distribution
Standard GPR4850D GPM48P (With Ethernet Port)

AC power distribution: single phase input, AC breaker @ general line (100A/2P);

DC power distribution: battery 100A*4(fuse);

LVLD: 63A×3 32A×5 16A×4 (MCB capacity optional)

LVBD: 32A×3 16A×4(MCB capacity optional)

 

4. Operating Principle

 

AC power is first input AC-INPUT MCB and then feed into the rectifier module after lightning proof and filtering. AC-INPUT acts as protection to over load and short circuit to AC power. The user’s battery is connected to the DC output side through MCB BAT and KM2, and the circuit breaker provides disconnection control, over-load and short-circuit protection to the battery.

Under normal conditions, every parameter of rectifier modules and power distribution unit are all under control of the monitoring module, operating according to the pre-set parameter or user’s commands. If AC mains faults, the battery will power to the system. With the battery discharge, the terminal voltage of the battery starts to descend. When battery voltage is under -47V±0.5V, the monitoring module sends DC under voltage alarm signal and when battery voltage is under -46.0V±0.5V (adjustable), the KM1cuts off non-priority loads and retaining power to priority loads. If battery voltage drops to -43.0V±0.5V (adjustable), the KM2 will cut off output of priority loads 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, users can send command to activate or inactivate according to the demanding.
