Constant Voltage Transformers

CVT maintains voltage using ferro-resonance principle where large changes in input voltage result in small changes in output voltage. Our transformers are built to filter any distortion

Key features

  • Instantaneous regulation
  • Over current protection
  • Stability with temperature
  • Filtration of all spikes and over voltages
  • Isolated supply
  • High reliability as no semiconductors/ moving parts used
  • Constant voltage over a large input range
  • Inherent short circuit protection
  • Maintenance free

Specifications

Input Volts 180-300V AC
Output Volts 220/230V AC +/-1%
Frequency 50 Hz
Load Regulation Better than 2%
Current Lamination Inherent
Full Load Efficiency 87% (approx)
Transformer Type Ferro-resonant
No Load Loss approx 15-22% of the rated VA capacity
Frequency Variation 106% change in output voltage for every 1% change in frequency

APPLICATIONS

Computers Data Processing Equipment
Telecommunication Systems Electrical & Electronic
Biomedical Equipment Color Photography Labs Testing Labs

Note:- CVT can be only designed up to a limitation of 5 KVA.

Caution

  • Place the CVT away from magnetic storage and display devices like monitors, diskettes, tapes etc.,
  • Keep it in such a place that plenty of air circulation is provided to it.
  • Make sure that there are no loose connections.
  • Do not place anything on top of CVT during operation.
  • Switch off CVT when frequency variation exceeds 50+/-1Hz
  • Do not use the highly inductive loads like motors.
