The Dual-Input Line-Low Frequency UPS 60KVA delivers reliable, uninterrupted power protection specifically designed for critical medical applications requiring pure sine wave output and exceptional stability.
Primary components include rectifier and inverter modules forming double-conversion circuit (AC to DC to AC), plus static bypass, maintenance bypass, and battery charge/discharge circuits. Mains power and bypass switching via thyristors in reverse parallel configuration acting as transfer switches.
