    Automatic / Emergency Rescue Device (ARD / ERD) is a device Installed for an Elevator which is only used Incase of a power failure or blackout in a building. An ARD / ERD is exremely useful for preventing passengers from becoming trapped Inside an Elevator during a power failure.

    POWERTEK 1Phase Input and three Phase output lift ONLINE ARD / ERD is specially designed to run three phase electrical motors by handling high inrush current of the motors. It proves to be a helping hand to convert 1Phase to three Phase by generating 3 Phase 4 wires continues output supply from its DSP Based Inverter system. Powertek  Lift ARD / ERD is embedded with isolated buck charging technology which provides constant charging voltage & current when Grid is available. It also senses the Grid failure & starts automatically by utilizing the energy stored in the battery back-up system. 3 Phase Lift ARD / ERD is capable of driving Lifts / Elevators & other 3 Phase machines. These three Phase UPS are designed to ensure uninterrupted three Phase supply to Lifts where three Phase Grid power is not available.
