Constant Voltage Transformer (CVT) And UPS
Constant Voltage Transformer (CVT) And UPS
Elent Electronics Pvt Ltd manufactures Constant Voltage Transformers (CVTs) And UPS. In Elent 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; and the perfect answer and remedy for most electronic equipment. UPS is available in Offline and Online range, where Offline consist of E-series and Pro-series models and Online consist of PS/3-Series, Eco-Series and Max-Series models.
Constant Voltage Transformer:
- Input voltage – 180 V-260 V (other choices on request)
- Line frequency – 50 Hz
- Output voltage – 220/230 ±1%
- Output stepload response – 2 cycles (30 to 40 milliseconds)
- Efficiency – 90% (approx) under full load conditions
- Output wave form – sinosidal
- Wave form distortion – 5% (approx) under full load conditions
- Load power factor – 0.75% lag to 0.9% lead
- Ambient temperature – -5ºC to 50ºC
- Transformer type – ferro-resonant
- Effect of frequency – 1.6% (approx) change in output voltage for every 1% change in line frequency
Constant Voltage Transformer:
- 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 1/2 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)
- Built in AVR
- Short circuit protection
- Cold start provided
- Overload protection
- Low Battery cut-off
