Lift Emergency System

WHAT IS EMERGENCY RESCUE DEVICE? An Emergency Rescue Device (ERD) is an electronic and electrical apparatus that provides emergency power to the elevators with 3-phase power supply, when the input power source or mains power fails. An ERD differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries through a dedicated Power Bank.
