Products Information
Ideal Application of Pure Sine Wave Inverter
Telecommunications
End User equipment sensitive to the power supply interferences
All critical environment which needs stable, reliable and uninterruptible true sine wave power supply
Features & Benefits
SPWM technology, true sine wave output.
Advanced anti-jamming technology, highly efficient filter, good electromagnetism compatibility, compatible with all kinds of communication equipment.
Good adaptability of RC and RL loads.
Automatic bypass. Transfer time is less than 8ms when failure. Our pure sine wave inverter allows supplying power to the load without interruption.
LCD displays the operating status of inveter, load and battery capacity etc.
Monitoring software offers several different communication and connection options(RS232 and SNMP) to manage your inveter.
Modular design allows for quick repair and easy field upgradeability.
Extra low noise and good overload capability Applications Telecommunications.
End user equipment sensitive to the power supply interferences.
All critical environment which needs stable, reliable and uninterruptible true sine wave power supply.
