Rectifier-Charger Units NRT Series for Reliable Power Supply Applications

ZVU are used at power engineering facilities, industrial enterprises, as well as in direct operating current networks of traction and transformer substations of the railway and are designed: <ul> <li>- for charging maintained and low-maintenance lead-acid batteries, sealed lead-acid batteries with gas recombination, lithium-ion and nickel-cadmium batteries (AB);</li> <li>to keep the AB in constant recharge mode;</li> <li>for parallel operation with the AB to the load;</li> <li>for supplying power to the load when the AB is switched off;</li> <li>to provide galvanic isolation between AC and DC circuits.</li> </ul>Designation - NRT (2x) K.N + X.Y, where K / X - rated output current of the main / additional channel (15 - 400 A) / (25, 40, 60); N / Y - rated output voltage of the main / additional channel (24, 48, 110, 220 V) / (24, 48 V).
