Lingfran - Model ZBW-50KVA -3-phase 50kva Solid Circuit Voltage Regulator
All mains powered equipment requires a supply which is maintained within certain limits. Too low and the equipment will malfunction, too high and the equipment could be serious damaged. In many developed and developing economies, power demand is outstripping supply, giving rise to large voltage swings, surges and brownouts in the supply. Whatever your national or international power supply requirements, voltage stabilisers can ensure your equipment receives the power it needs to operate efficiently and without interruption. Biggest hindrances for electronically operated devices are voltage fluctuation due to sag, spike, noise & transient. It causes loss of data, machine damage & poor productivity. Lingfran 3-phase 50kva solid circuit voltage regulator offers constant voltage to the electronic operated machines using SCR technology.
