Industrial Strengh 3KVA Variac

A 3 KVA Variac also known as an Auto Transformer is designed for Industrial/ Laboratory use. This Auto Transformer provides 30Amps of current at 100VAC output. The front panel contains an analog volt meter and two sets of binding posts that can accommodate spade connectors and banana plugs to connect to the AC source and the equipment being tested. It does not include a power cord or AC recepticle. It is ideal for many applications including UPS's, Satellite Equipment, Transformers, Telecom Equipment, Railroad Switching, Automation Control and for general use in Physics, Chemistry & EE Labs.

• Input Voltage: 110VAC @ 60Hz
• Output Voltage: 0-130VAC
• Dimensions (approx.): 7.5" x 8.5" x 7"

This unit is VERY popular for home coffee roasting. It allows much greater control of the temperature of the roasting of coffee beans. They can also be used in science lab, audiophile (Great for old Tube Amplifiers), Science lab, hobby, film & video lighting applications. This Auto Transformer converts AC voltage to AC voltage. So, if the AC input from the power grid is 125VAC and the desired input for you application is 90 VAC then this Auto Transformer may be placed in series and the adjustment to 90VAC can be accomplished. The The unit will not affect the cycle rating from your power source.

Note: Variacs are not compatible with most GFI (Ground Fault Interrupter) wall outlets.  We have found that the inductive load that the Variac represents is not compatible with most GFI circuits and they will trip the breaker.
