Charge and rectifier thyristor VT series (ZVU-VT) is a charging and recharging device with constant voltage outputs designed to supply consumers and parallel operation with stationary open lead-acid ABs, sealed lead-acid ABs with gas recombination and nickel-cadmium ABs.
The ZVU-VT provides all modes of charging/recharging the AB and supplying the load fully automatically. The operating personnel intervenes only in case of error signals or to perform standard periodic checks.
ZVU-VT includes a three-phase thyristor bridge rectifier with an output LC-filter and an output power diode to ensure parallel operation with similar devices. To provide galvanic isolation between AC and DC networks, a transformer is installed at the input of the PDU.
