3. Description

The GPE48150A embedded power system consists of the power distribution frame, monitoring module and rectifier module. The whole system is of high reliability and performance, and can be operated through PC software.

4. GPE48150A System Configuration

GPE48150A consists of power distribution unit, rectifier module (from 1 set, up to 3 sets) and 1 monitoring module. The configuration is optional, as following table:

5. GPE48150A 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. LOAD1-, LOAD2-, LOAD3-, LOAD4- are connected with two load down contactor KM1, KM2. 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 monitoring module will control the contactor KM1 to cut off LOAD3 and LOAD4 and retains power to LOAD1 and LOAD2 . If battery voltage drops to -43.0V±0.5V (adjustable), the monitoring module will control the contactor KM2 to cut off output of LOAD1 and LOAD2, 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.
