PBI systems (buffer pulse rectifiers) are DC power units tailored to the needs of industrial plants with high requirements in terms of operational reliability, technical specifications and supply reliability.

Designed to power loads in cooperation with a battery or directly from the power supply. PBI type power supplies are designed for use in DC uninterruptible power supply systems, to power receivers and charge batteries with nominal voltages of 24VDC, 48VDC, 110VDC, 220VDC or other devices compatible with their specifications. The systems have been constructed based on contemporary trends in the field of power electronics. Independent, parallel operation of the modules leads to redundancy work, which ensures uninterrupted operation of the power supply in the case of failure of one of the modules. PBI M rectifier modules are designed for installation in 19" cabinets, creating a compact structure optimized in terms of the working conditions of modules. The use of modern power semiconductor devices affects their high efficiency and stable battery charging performance, in line with the recommendations of EUROBAT.
