The main component of SOJI UPS single-phase 60VDC elevator rescue device is a battery integrated with a frequency converter ('220VAC, 50Hz / 60Hz charger') that supplies power to the elevator control system, including control circuits, brakes, and door components in the event of a power failure. In this case, the main power source for the motor drive frequency converter is supplied directly from the battery, with a voltage of 48VDC / 60VDC / 72VDC / 96VDC / 120VDC depending on the model. This device can be used in emergency evacuation operations for all elevator control panels with frequency converters of any power rating, as the DC bus of the inverter is charged directly from the battery.
Rescue devices typically require 220Volts to activate their own main power supply, and a DC source (battery) is connected to their DC bus to convert power. This DC bus voltage varies from 48V to 120V depending on the specific model.
