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:
| Configuration | Rectifier Module | Monitoring Module | Power Distribution |
| Standard | GPR4830A R01 |
GPM48VI
| Load output 1 way |
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).
