Time (0:05). A Variac control is a brand name for a - Chegg

A Variac control is a brand name for a common laboratory variable voltage transformer, a device that converts AC current to DC, and also controls the voltage of the electricity. At a low setting, the low voltage allows less current to flow through a heating mantle, and it doesn't heat much. At higher settings, more voltage allows more current

Apr 03, 2008 Use a dimmer to control heating mantle Used heating mantles can be picked up for very cheap these days, so I've become interested in how to regulate the power for these in a cheap way. ... Variac is also a well-known brand for these autotransformers. Next best would be a solid state dimmer using triac thyristor circuitry. This just chops out ...

In this case the heating mantle is plugged into a variac which is adjusted to heat the reaction to 100o C, then the variac is plugged into the RTU. A set point of 110o C is entered into the J-KEM 3300 and the “Limit Switch” is set to “High Limit” and the “Latching Switch” is set to “Latching”. In this configuration the variac ...

The variac is a device that modulates AC current. Wall current is 120 V; a variac can adjust that to anywhere between 0 and 120 V. Plugging the heating mantle into a variac allows you to control the temperature by controlling the voltage supplied to it. Test the mantle and variac by briefly turning the dial up to 100%.
