Itech Application Note – Inverter testing for Elevators

When the mains is on, it automatically recharges and keeps the batteries in top condition.
When mains fails it continuous to run the Elevator and bring it to a halt at the next floor.
The cabin bulb remains on and doors of the automatic lift opens on reaching the next floor.
Thus it enables safe walk-out for passengers – a real boon in these days of unpredictable power failures!
