What Is a Three-Phase Panel Variac Used For?
A three-phase variac is usually built as three variable autotransformer sections turned by one shaft, so a single control raises or lowers all three line voltages together. That makes it a common way to bring three-phase motors, heaters and test circuits up to voltage gradually, or to run them below full voltage for experiments in electrical machines and power laboratories. A smooth, linear output means the voltage changes evenly as the control is turned, without steps.
Frequently Asked Questions
What does low magnetizing current mean?
Every transformer draws some current simply to magnetize its core, even with nothing connected. A low magnetizing current means little power is taken from the supply when the variac is lightly loaded or idling.
What does an export enquiry need to include?
The quantity, the destination country and port or city, your preferred delivery terms such as FOB or CIF, packing or labelling requirements, and any tender reference.
Who makes this three-phase variac?
JLab — Jain Laboratory Instruments Pvt Ltd — at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of electrical training and laboratory equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. JLab builds this variac at its own works instead of reselling a trader’s stock, and colleges, panel builders, dealers and importers deal with the factory directly. JLab exports worldwide and ships to buyers in every region, for example Kazakhstan in Central Asia, Guatemala in Central America and the Caribbean, Guyana in South America, Australia in Oceania and the Maldives in South Asia.
