These ARDs are designed to match latest types of VFDs which can operate from single phase power supply. With two small SMF batteries it can perform rescue operation of a small elevator with 5/7.5 H.P. motor.
- Auto shutdown of UPS after rescue operation, so the batteries are not over discharged after prolonged power failure.
- Programmed delay to start UPS after power failure.
- Output in mains mode through NC contact of relay, so in any case if mains is present, power is available at output.
- Low ripple battery charger for smooth charging of batteries and longer life.
- One Input & one Output potential free contact for communication.
- Power failure source selection option
- Single PCB and only one power transformer
- Less than 1 mA current consumption in idle mode
- DZ input for shutdown
