DC/AC Inverter(SET24/220-2KLC)


Features:
1.With micro-CPU control, DC/AC inverter is an intelligent model product with good designing and reliability.
2.Adopting SPWM technology, with the output of stabilized voltage and frequency, pure sine-wave.
The inverter has good compatibility, built-in by-pass switch, high overload feature for reliable and continuous power supply.
3.AC power type and DC power type:
--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.
--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.
4.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.
5.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. 6.This function is very suitable for the communication station in which there is no person on duty.
7.Support network communication system, and power working state can be monitored by the supervision software.
8.DC/AC inverter provides with two dry connectors which can be used for DC input fault checking and AC output problem warning.

Remarks:
1.To maintain the battery, the inverter will start only when the battery voltage is within the starting voltage scope.
2.When entering into the working state, as long as the battery voltage is within the scope of turn-off voltage, the inverter can work properly. There will be a low-voltage alarm when the battery voltage drops to the lower limit, if below the power-off voltage, the inverter will power off automatically.
