Starting Circuitry
Powertek Rectifiers are designed for 3 phase, 50 Hz AC input supply and are available for operations at any voltage between 380 and 440 volts covering a wide range of voltage fluctuations.
It is recommended that the input to the rectifier should be connected through a proper protective device, to provide positive protection to personnel and the system, in the event of maintenance or in case of a fault.
Output Control
The function of the variable output controls is to control the voltage or current or its operating range by varying input voltage to the main transformer primary.
The DC output voltage variation is achieved sleeplessly 0-100% by means of an ON LOAD roller type voltage regulator.
DIODE
Silicon diodes are tested in house, similar PIV batch and same forward drop diodes are used in the equipment for equal load sharing and reducing the power losses of diodes.
LAMINATION CORE
We use imported CRGO Lamination core which have minimum power losses and results in better efficiency of equipment and saving in energy bill.
PAINTS
Epoxy paint is used which is resistant to acidic environment of plating process and enhance the life of the equipment by preventing it from corrosion.
METER
We use reputed make DC meters only which are very accurate and durable.

CONSTANT VOLTAGE CONTROLLER (OPTIONAL)
We offer CVC Electronic attachment with rectifier equipments, which will maintain constant Output Voltage or Current as per setting automatically irrespective of input voltage variation.
Roller Type Regulator
- No waveform distortion at any Load.
- Electrical waveform is like a moving wheel. For 50% Rated Voltage the Dia of wheel is reduced accordingly i.e. magnitude for a wave is reduced.
- Higher power factor Of more than 0.95 is achieved.
- The system is simple and can be repaired and maintained even by simple mechanic.
- The cost Of spares is very negligible.
- Over all losses is less.
Thyristorised Control
- Waveform distortion. It is like cutting the wheel by 50% and then moving the wheel i.e. wave form is cut as shown at full magnitude.
- The power factor is lower.
- The system is specified and needs specially trained Electronic Engineer to repair and maintain.
- The cost Of replacement is very high.
- Over all losses is more.
