PROUPS is a completely domestic product designed by PROSIS engineers in the Prosis Elevator R&D unit for elevator rescue and power supply purposes.
It has a 24-volt DC battery input and an idle 240V AC output. The modified sine wave UPS operates with a voltage feedback system at 50-60 Hz frequency, delivering 1500VA power with 77% efficiency.
PROUPS OPERATION
The AC 220-230V supplied to the device input is immediately transferred to the AC OUT output. When the mains power is cut off, the driver circuits generate AC voltage at the output using two batteries (24VDC).
The battery connection is controlled by an automatic fuse, which engages or disengages as needed. If the current exceeds the fuse limit, the automatic fuse operates to protect the device and batteries.
The front panel of the device features two indicators that display error messages and battery voltage levels.
