*Extra long standby time. And additional battery connections possible for longer power supply time according to customer s requirements.
* Smart RS232 communication port for computer screen monitoring of power supply and UPS status, and for automatic file saving and computer shutdown.
*High reliability with CPU control.
*Automatic voltage regulation (AVR), most suitable for areas where commercial power supply is unstable.
* Self-diagnosis function, capable of detecting status at inverter and battery in the UPS.
*Protections against overload, short-circuit and low battery
