uZen UPS 301 – 3/1 Phase

ZENER UZEN UPSThe ZENER uZen 301 series is a Three phase input-single phase output, double conversion, regenerative, VFI, MPWM, IGBT, microprocessor based UPS with galvanic isolation for comprehensive power protection. The Galvanic isolation via transformer (as per IEC62040) eliminates problems associated with common mode noise, neutral and earth potential drifts which can cause irreparable loss.

Designed and built for the harsh Indian power conditions, these UPS systems are capable of delivering highly demanding surge loads without performance de-rating. Complies with all international standards.
