4. GPE48300A System Configuration
GPE48300A consists of integrated cabinet, power distribution, rectifier module (from 1 set, up to 7 sets) and 1 monitoring module. The configuration is optional, as following table:
|Configuration||Rectifier Module||Monitoring Module||Power Distribution|
AC power distribution: single phase input, 1-pole AC breaker @ general line (63A/3P);
DC power distribution: battery MCB 200A×2;
LVLD: 63A×4;32A×4(MCB capacity optional)
LVBD: 32A×2; 16A×2 (MCB capacity optional)
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. LVLD and LVBD are connected with 2 load power down contactors 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 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.

(1) 55~65°C, module power derates, derating method is auto derating; 65°C, 176~280Vac, long term regulate output at least 80% rated power.
(2) 55°C, can output max. output power of module, without over temperature protection, and components can operate normally.
(3) Bacause of liquid crystal’s feature, when exceeding liquid crystal operating temperature range, the screen may be over bright or turn dark with no display.
(4) When lots of dust enter module, short circuit may happen to circuit inside the module. Under damp weather, after dust absorb water, insulation inside power decreases, which may lead to creepage or short circuit inside module. Therefore, in places with lots of dust, please take dust proof measure and clear dust-proof mesh and dust inside module. If dust is too much, the fan may be blocked. The module is cooled by fans, not enough air volume may cause hot inside module can’t be dissipated, then the module will enter over temperature protection in advance.
