3. Description
The GPE48300A integrated power system consists of power
distribution, integrated cabinet, monitoring module and rectifier
module. The whole system is of high reliability and performance,
and can be operated through PC software.
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 |
| Standard | GPR4850D | GPM48P | 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) |
5. GPE48300A 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. 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.

| Ingress protection | The unit can operate normally when the diameter of dust particle is
more than 5µm, with density ≤3*104 /m3. The dust shall not be conducting, electromagnetic or corrosive. |
Notes: (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. |
