    AUTOMATIC / EMERGENCY RESCUE DEVICE (ARD / ERD)

    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.

    3 Phase IN - 3 Phase Out


    Catalogue


    POWERTEK  Three Phase 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 during Grid absence by generating 3 Phase 4 wires output supply from its back-up system and switch it off after receiving rescue completed Signal(DZ Signal). Powertek ARD / ERD  is embedded with  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 ARD / ERD is capable of driving Lifts/Elevators & other 3 Phase machines. These three Phase ARD's are designed to ensure uninterrupted power supply to various industrial houses. It also provides a healthy chance to win the hearts of various Industries by its technological advancement & remarkable
