Transformer UPS BFIz

INDUSTRIAL UPS BFIz 1÷500 kVA

Industrial UPS BFIz are complex systems made individually for the customer’s needs.

About product

Every industry has its group of devices that play a critical role in a specific industrial process. For these devices, it is necessary to ensure proper power supply parameters to ensure the course of the technological process, regardless of the parameters of the power supply network, and in case of a power supply network voltage failure, to ensure the possibility of uninterrupted continuation of operation within a certain time.

This function is fulfilled by the guaranteed power supply system based on the BFIz-type inverter. Industrial UPS consists of a BFIz inverter, SKB static switch, PBI rectifier with batteries, ATS system, and guaranteed voltage switchboard.
