Communication Power Supply/Outdoor Wall-Mounted Power Supply
Principles of Power System
The system input is sent to the rectifier module input through a
63A/2P circuit breaker. Parallel AC C-level lightning protection is
used for lightning protection at the input end.
The rectifier module operates in parallel, and its DC output is
connected through a busbar to supply two backup battery packs and
DC loads. DC loads are controlled by fuses or air switches,
providing users with on/off control for each load and protection
against overload and short circuits.
Under normal system conditions, various parameters of the rectifier
module and distribution unit are controlled by the monitoring
module and operate according to their predetermined parameters or
user commands. If the mains power fails, the system will switch to
battery power supply. As the battery discharges, the voltage at the
battery end begins to drop. When the battery voltage drops to a
power down voltage point, the monitoring module controls the power
down contactor to operate and cut off the load; When the battery
voltage drops to the battery protection voltage point, the
monitoring module controls the action of the secondary power-off
contactor, cutting off the connection between the power system and
the battery, protecting the battery from excessive discharge. At
this time, the power system will stop working. When the external
mains power is restored and the rectifier module resumes output,
the system will resume normal operation. The monitoring module can
detect and control the working status of the entire power
distribution system. User commands can be issued through the
keyboard on the monitoring module panel, local backend PC, and
remote central control room. The system's working status and
parameters can be displayed on the monitoring module LCD screen,
local backend PC, and remote central control room. The system can
collect various environmental variables, including smoke, door
magnets, water immersion, temperature, and humidity, by configuring
appropriate sensorsReport.
