Description
The SZVU is manufactured in accordance with the technical specifications VRAT.657.00.00 TU and represents a direct current system with a nominal voltage of 48 V, capable of charging two groups of four or five series-connected storage batteries with a nominal voltage of 12 V and a capacity from 20 to 300 Ah (hereinafter – batteries).
The SZVU SMART-S is designed to supply power to consumers of railway transport and industrial enterprises (hereinafter – loads). The SZVU SMART-S provides load power supply, buffer mode maintenance, and accelerated charging of batteries with a constant current at a nominal voltage of 48 V (60 V) from the AC mains.
When combined with parallel-connected batteries, the SZVU SMART-S forms a DC uninterruptible power supply system, ensuring power supply to the load from the batteries in the absence of an AC power network.
