Varivolt is the most effective device meant for operation from a nominal input voltage of 240V 1Ph & can give output voltage anywhere between 0 to 240V or 0 to 270V 1Ph by simple transformer action. Three such Varivolt connected electrically in star and mechanically in tandem, become suitable for operation from a nominal input voltage of 415V 3Ph and can give output anywhere between 0 to 415V or 0 to 470V 3Ph.
“VARIVOLT” AUTO TRANSFORMER is a continuously variable voltage auto transformer, having a movable carbon tip, fixed to brush arm sliding on a silver plated commutator. Rotation of the brush arm by either manual or motor drive, delivers an output voltage from zero to or above line voltage. “VARIVOLT” conforms to I.S. 5142.
Varivolt Autotransformers: Built for Precise Voltage Control and Durability
Our high-current transformers exceeding the industry standard! We offer single, two, and three-phase models ranging from 225 Amps up to 2000 Amps. Our innovative paralleling techniques achieve this impressive feat, surpassing the previous limit of 200 Amps for toroidal transformers. These robust transformers boast exceptional features like precise current sharing (±2%), easy transportation with separate radiators, a reliable gear-driven motor drive, and bus-bar terminals for high-current connections. Plus, they benefit from all the advantages of our oil-cooled autotransformers.
Unlike other voltage control methods, Varivolt offers exceptionally smooth and precise voltage adjustment. It boasts a durable build for heavy-duty use, with minimal maintenance required. Additionally, Varivolt delivers a clean output waveform, protecting sensitive equipment.
Varivolt transformers are designed for low maintenance. However, some occasional care is necessary:
Varivolt transformers offer several advantages compared to alternative solutions:
