Model Functions
l With micro-CPU control, DC/AC inverter is an intelligent model product with good designing and reliability.
l Adopting SPWM technology, with the output of stabilized voltage and frequency, pure sine-wave.
l The inverter has good compatibility, built-in by-pass switch, high overload feature for reliable and continuous power supply.
l AC power type and DC power type:
l --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.
l --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.
l With the excellent designing, DC/AC inverter can be auto switched to bypass on the running state, its easy to maintain and replace the battery without effecting load power supply.
l 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.
l Support network communication system, and power working state can be monitored by the supervision software.
l DC/AC inverter provides with two dry connectors which can be used for DC input fault checking and AC output problem warning.
