1. GPE48150 System Configuration

GPE48150 consists of two layers of 1U insert frame. The first layer consists of rectifier module (at least 1 set, up to 2 sets) and 1monitoring module . The second layer frame consists of rectifier module, and can be up to 3 sets. The second layer is optional, depending on the customer. The configuration is optional, as following table:

2. GPE48150 Operating Principle

AC power (single-phase or three-phase) get into the rectifier module through the AC input terminal (L1, L2, L3, N). OUT+, OUT- is DC power system output terminal. User load and the battery access to the power system DC output terminal through the power-down contactor. load power-down contactor is normally closed under situation of no trigger, battery power-down contactor is normally open under situation of no trigger.

In normal conditions, various parameters of rectifier module and power distribution units are controlled by the monitoring module, and work according to the predetermined parameters or user commands. If there is a power failure, at this time system will be powered by battery, with the discharge of the battery, battery terminal voltage begin to decline, when the battery voltage is lower than 46.2V (adjustable), the monitoring module reports DC undervoltage alarm signal, when the battery voltage drops to 45.6V (adjustable), the monitoring module controls the load power-down contactor, turning off the load power supply. When the external power recovery, the system will restore the normal working state of the battery and the load (the above monitoring data is the system default value, the user can re set).
