The STC-CPL48150ER embedded power system consists of the distribution frame, monitoring module and rectifier module, with functions of AC lightning proof and DC current sharing. The monitor module supports outside signal input, communication transformation, AC/DC detection and contactor control. The whole system is of high reliability and performance, and can be operated through PC software.
1. General Introduction 1.1 System configuration
The system consists of distribution unit, rectifier module (from 1 set, up to 3 sets) and monitoring module. The configuration is optional, as following table:

1.2 Operating principle
AC power is first input AC-INPUT MCB and then fed into the rectifier module after the EMI 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 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 the voltage is under -47V±0.5V, the monitor send DC under voltage alarm signal and when the voltage is under -46.0V±0.5V (adjustable), the KM1cuts off non-priority loads and retaining power to priority loads. If the 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.
