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.

2 Phase IN - 2 Phase Out

Catalogue

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.
