The device is powered by 5 pieces 12V/7h lead acid batteries. The one that cuts off the batteries when there is mains energy.
It is considered healthy through 220Hz safe signals after the power is cut off (kg).
It is specially designed for elevator control panels with speed control device inside. Not suitable for direct elevator drive motor operation. The device provides pure sine output, unlike ordinary UPS’s, and provides at least mains quality supply performance. The advanced charging algorithm is designed to get the longest service life from the batteries.
Device output is isolated from mains However, in cases where there is energy in the network, the device transfers the network to its own output. This just means that the output is not isolated from the mains at that moment.
The device is available in a durable and space-saving painted sheet metal box to be mounted on the elevator control panel.
