    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.


    Automatic / Emergency Rescue Device Back-up is a Static converter which is used to generate Double Phase output with pure sine wave to supply power for  Lift / Elevators during Grid failure and switch it OFF after receiving  rescue signal (DZ Signal). Powertek  provide 5 manually selectable timers 0 Sec, 6 Sec,12 Sec, 20 Ssec & 30 Sec  to switch off  ARD / ERD after receiving DZ Signal.but if rescue (DZ Signal) not received from control panel, ARD / ERD will shutdown automatically after  3 Mint. for saving DC power  of  SMF Batteries for next cycle when Mains Supply restored.  ARD / ERD Back-up consists primarily of a sinewave inverter  with SMPS type Battery charger  & change over module with SMF  Batteries. The charger is a controlled rectifier that provides a constant voltage and  constant current  to charge the Battery bank when the Mains Input  supply is available.
