Major1PC power (2-15 kVA) conditioners are hardwired, single-phase units featuring automatic voltage regulation. Major1PC units provide full protection against electrical noise created by lightning, utility switching, and electric motors. Voltage sags and spikes, switching transients and induced surges are all eliminated using Microprocessor-controlled, Zero-Current tap switching technology and a surge suppression circuit, which is linked to a shielded isolation transformer (with input and output filters).
Major1PC units hold output voltage regulation to a maximum of ±5%, with an input voltage window of +15% and -25%. Response time to any line variation is less than 1.5 cycles.
