Description

When utility power is not present, the backup system first uses the regenerative power to recharge the batteries and passes any extra power to the resistor bank to be dissipated as heat. After the first 2-4 elevator cycles, the batteries are typically sufficiently drained so that all the regenerative power goes into recharging the batteries and the resistor bank is no longer used.
