Guaranteed DC power supply system SBPM-ZVU

System of guaranteed DC power supply SBPM-ZVU - charging and rectifying device (hereinafter referred to as the Product). It is designed to receive AC electric energy and convert it into DC electric energy, charge/recharge ABs, as well as to supply DC consumers.

The Product is a three-phase thyristor bridge rectifier with LC output filter.
To ensure galvanic isolation between AC and DC networks, the Product has a matching transformer at the input.

Output voltage regulation modes:
- Soft start;
- Buffer "IUU" charge;
- Accelerated (automatic) "IUU" charge;
- Manual charge.

Main functions:
- Thermal compensation of battery charge voltage;
- Parallel operation of the sounders; - Compensation of voltage drop in the cable;
- Monitoring of AB circuit integrity;
- Management and control of AB room ventilation;
- Automatic reclosing;
- Logging of events;...
