TDGC2-3 3KVA Variac Variable Transformer,220V Input 0-250V Output 12Amp
Product Description :
A 3 KVA Variac also known as an Auto Transformer is designed for Industrial/ Laboratory use. The 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. 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.
Product Description
The Voltage regulators are used to adjust the voltage from 0 Volts up to the maximum voltage for which they have been designed and among the most usually applications,No additional wave from distortion.The main applications are :
Laboratory control equipment
Lighting equipment
Temperature controls
Motor speed control
Controlling for other transformers
Etc.
Manually Operated Rotary Knob to control output voltage, by means
of a control button on the shaft of the voltage regulator (Variac)
which allows to act on the brush and achieve the desired voltage.
The voltage can be smoothly varied between turns as the brush has
a relatively high resistance (compared with a metal contact) and the
actual output voltage is a function of the relative area of brush in
contact with adjacent windings.
