1. Application:
Post and telecommunications industry for 48V, -48V or 24V DC panel of program-controlled switchboards, computer rooms, network, billing, server, and emergency lighting and other plac
2. Protection against:
Input/output low or over voltage, short circuit
3. Product description:
The series are designed specifically for post and telecommunications industry for 48V, -48V or 24V DC panel of program-controlled switchboards, computer rooms, network, billing, server, and emergency lighting and other places. Normally, AC powers to critical loads through the static switch power supply. Once the power cut or other abnormal conditions beyond the normal range, electrical equipment power supply will shift to the DC (battery) of inverter power.
4. Product feactures:
With micro-CPU control, an intelligence model product, good designing and reliability are the advantages
Adopting SPWM technology, with the output of stabilized voltage and frequency, pure sine-wave
Good compatibility, built-in by-pass switch, high overload feature for reliable and continuous power supply
Working type--- AC power type and DC power type:
1. AC power type means the city power supply is main when the city power is normal, when city power is off, inverter comes into work state
2. DC power type means the inverter power supply is main when the city power is normal, when inverter power is off, city power comes into work state automatically
With the excellent designing, can be auto switched to bypass on the running state, its easy to maintain and replace the battery without effecting load power supply
In case there is battery voltage high/low or overload, the overload warning shutdown output, when battery voltage recovers normal, battery voltage recovers; Power supply output will auto recovers in 50 seconds after overload off. This function is very suitable for the communication station in which there is no person on duty
Support network communication system, power working state can be monitored by the supervision software
