We are engaged in manufacturing high quality Electronic Voltage Stabilizer that quickly response for fluctuation in line and load. Our Stabilizer takes approximately 5 cycles for change in load and 10 cycles in the change of line. Operating Principle Our regulators ensure controlled firing through inverse parallel pair of SCR’s measured in shunt leg of auto transformers. The approximate voltage obtained when auto-transformer increases or decreases from the input voltage, which depends on the phase angle from where the SCR is fired. Output folds back when current exceeds.

We manufacture D.C. Motor Controller that is specially designed to provide a speed adjustment ranging from zero to full rated speed. Our D.C. Motor Controller functions with D.C. Motors Shunts or compound type through supplying two rectified main supplies to field circuit and armature. The supply of field is carried to ZZ(±) and Z(-) which is at fixed voltage. Afterwards, the armature supply is carried out both the terminals A and AA. This supply varies from 0-80% from the supreme supply voltage through the means of wave controlled system. The SCR’s (Thyristors) is fired by a trigger circuit controlled by a superior quality amplifier. This amplifier works from a small D.C. voltage input. As the result, the speed of the motor remains constant. Salient Features Our D.C. Motor Controllers are grounded on the basis of Thytristors (SCR) having conduction angle managed by completely encapsulated trigger circuits that deliver wave rectification on Armature and Field.Light in weight and easy to maintain transformersTechnically advanced Field Rectifier, SCR, DIODE Unit and Triggering CircuitTerminals are fixed on the lower portion of the rackConsist of current limiting circuits that ensure protection to silicon devicesHave high rupturing capacity fuses thereby ensuring prevention from short circuit conditionsArmature Circuit with interlocking system Capacities Available Single Phase : 1, 2, 3, 5, 10, 15 H.P. and above.Three Phase : 5, 7, 5, 10, 15, 20, 25, 50, 75, 100, 150, 200, 250, 350, 500 H.P. & above Speed Regulation Feedback systems are standardAccuracy 1% of +10% mains voltage variationArmature IR CompensationTachometer GeneratorArmature voltage D.C.
