1. Tracing the latest trends of the world communication power
supply technologies; using the advanced power supply control
technology and
2. Ultra-small design for rectifier, with high power density up to
854 mW/cm3 ;
3. Advanced modularized design and automatic current equalizing
technology enabling N+1 backup mode of the system capacity and
convenient expansion;
4. Perfect electromagnetic compatibility, minimum electromagnetic
radiation, and minimum surge current at system startup;
5. Fully intelligent design; configured with centralized monitoring
unit; designed with telemetering, telecommand and telecontrol
functions; implementing computerized management, for the purpose of
unattended management through communication with the remote central
monitoring center, and thus meeting the demand of contemporary
communication technology development;
6. Power supply control technology effectively combined with
computer technology, for the sake of real-time monitoring over
parameters of the rectifier and AC/DC power distribution;
7. Supporting three-phase electric grid input or single-phase
voltage input; providing a wide range of input voltages (80 VAC ~
300 VAC); applicable toregions with unstable power supply;
8. Providing emergency power supply through battery in case of
mains power failure; supporting automatic mains-generator switching
function;
9. Supporting the configuration of 12 rectifier modules at most as
required;
10. Providing automatic battery management; powering communication
equipment in the parallel float recharging mode; through monitoring
unit, automatically measuring the battery recharging/discharging
current and controlling the rectifier of floating/equalizing
recharging to the battery;
11. Providing two-stage power shutdown function. When the system
power supply switches to the batteries, loads are shifted off in
two batches according to their different degrees of importance.
When the battery voltage is lower than the primary shutdown
voltage, audio and visual alarms will be given and the less
important loads will be shut down, to maximize the working time of
the most important loads. When the battery voltage is lower than
the secondary shutdown voltage, audio and visual alarms will be
given and the important loads will be shut down, to avoid the
battery from excessive discharging;
12. Multi-level lightning protection technology ensuring high
reliability of the overall equipment;
13. When the system is faulty, the monitoring unit will give audio
and visual alarms, and send alarm information to the remote central
control room.
14. Using LCD to display the system information in text and graphic
modes;
15. Flexible power distribution mode supporting upward or downward
cabling as required;
16. Drawer structure facilitating transportation, installation, and
maintenance;
17. Intelligent fan cooling mode ensuring minimum noise in
operation;
18. High reliability, with MTBF ≥ 220,000 h;
