Product Description

Features:
  • In our CVT, the AC mains powers the input winding which is widely separated physically from the isolated output winding
  • The input winding normally runs at very moderate Flux linkage levels. The output winding exhibits an intrinsic energy characteristic and this energy storage operates in conjunction with mains capacitor to produce self-generated AC flux field which is indirectly excited from the input winding
  • The result is instantaneous voltage regulation. No transient and spikes. Sinewave output. A perfect answer and remedy for every electronic equipment

CVT Specifications:

Salient Features:
  • No semiconductors or moving parts used, hence very high reliability
  • No feedback control used
  • Intrinsic current limiting and short circuit protection
  • Output voltage correction within ½ Cycle ( 10 ms) from no load to full load for specified load and line variation
  • Short term over load capability
  • Energy storage for line loss up to 3 ms at typical loads
  • Higher input voltage control range, for loads less than rated load
  • Very high line transient/spike rejection capability and excellent input to output isolation characteristics
  • Output floating (optional)

Range:

Recommendations:
  • Keep magnetic storage and display devices like Diskettes, Spools, Monitors etc. away from the CVT
  • Switch on the CVT before switching ON the attached peripherals and while switching off, switch OFF attached peripherals first and then the CVT
  • Avoid using the CVT for high inductive loads.
  • Check frequency before using the CVT with a generator. Recommended frequency: 50± 1Hz
  • Switch OFF the CVT when not in use

Applications:

Office & Business Equipment:

Computers, Electronic Typewriters, Ledger Posting Machines, Electronic Cash Registers, Telephone Exchanges, Facsimile [FAX] etc. CNC systems, Photo Typesetters, Tele-printer, Security Systems, etc.

Process Controls Medical Equipment:

Life saving emergency equipments in ICUs, X-ray Machine, Medical Monitors, Field & Lab Instruments, Communication Equipments.


Special Features:


  • Very High Voltage Correction Speed - Almost Instantaneous.
  • Very High Isolation between Input & Output to tilter EMI/RFI
  • Computer Grade Clean, Filtered continuous Power supply.
  • Built-in inherent protection against Under-Voltage, Over-Voltage & Over Load
  • Built-in Voltmeter provided to continuously monitor the output voltage
  • Output provided through 3 SOCKETS [for computer application - CPU, Monitor, Printer]
  • Higher Reliability as NO MOVING parts - Maintanance Service
