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.
