Transformers are critical equipment in the power supply chain of every industry and work 24/7 in most cases. The quality and efficiency of transformers therefore are very critical and make a significant difference to the industry both in terms of uptime and energy costs. Considering the importance of this, we are offering innovatively designed efficient transformers that help industries through superior performance and lower energy losses.
With over 250,000 installations in various applications, our transformers have a proven track record of performance over a long life-cycle.
Ultra Isolation Transformer (UIT): A double wound transformer with multiple shielding for Capacitive or Faradic Isolation (reduction of capacitive coupling). This transformer has very high attenuation of Common Mode transients thus preventing passage of voltage transients, spikes and galvanic leakage in the Common Mode from reaching sensitive electronic equipment like computers,medical equipment and CNC machines. It also addresses problems related to poor input neutral. The Ultra Isolation transformer can be designed to provide output voltages to suit machine requirement.
Salient Features:Low inter-winding capacitance Good DC galvanic isolation
High attenuation - 100 dB in common mode up to 10 kHz
Optimum transformer design ensures good load regulation
Galvanic Isolation Transformer(GIT)
A double wound transformer, which provides galvanic isolation and hence addresses problems related to input neutral. The Galvanic Isolation Transformer can be designed to provide output voltages to suit machine requirement.
Auto Transformer
Auto transformer is a transformer with a single winding(and therefore is without isolation) designed to change the output voltage to suit machine requirement.
