ZENER uZen HSC 303

ZENER uZen HSC 303

Specially designed online UPS for CT & MRI Scanners

Limits the Peak Power Consumption Utility (EB)

uZen HSC 303 operates at lower sanctioned power allowing it to use a low capacity generator. The programmable power consumption limit is 30% - 100% of input power.

  • 200VAC phase-phase
  • 4:1 crest factor, IPL facility*
  • Phase-phase and phase-neutral voltage regulation of ± 1% on 0-110% unbalanced step loading.
  • Remote power monitoring software.
  • Galvanic isolation at the output as per IEC 624001-3 for comprehensive power protection. Input to output galvanic isolation for operator and patient safety.

Double conversion Online with the latest MPWM technology using IGBT


10KVA - 200KVA

DC Bus192V/240V/360V/384V
Input voltage415V AC Three Ø & N
Input voltag window330 - 470V
Input Frequency50Hz ± 10%
Power walk inSoft start for 0-20 seconds power walk-in
Input power limiting facilityInput power limit adjustable from 25% to 100% of the unit capacity, for example: when activated for 25% for a 60KVA UPS, the maximum input power drawn will be less than 15KVA.Thus it facitates to operate a 60KVA UPS & Scanning machine at a lower power sanction from EB or lower generator capacity
