3 Amp Variac Variable Transformer, 300va Max, 0-130 Volt Output

3 Amp Variac Variable Transformer, 300va Max, 0-130 Volt Output



3 Amp Variac Variable Transformer, 300va Max, 0-130 Volt Output Feature :

Input: 120 volt AC, Output: 0~130 volt AC, 3 Amp Slow Blow Fuse

Max VA: 300VA, 3 Amp. Max (surge), 1 year warranty

A rating of 300VA means that at 100volt, the unit can sustain at maximum 3amp. If at 120 volt the unit can sustain at 2.5amp

Note that most device have surge (when first turn on) much higher than operating amp rating.

E.g, motor with 3 amp rating may have over 5 amp surge, and you will need 5 amp variac

Variac is a variable transformer and a great device for quality control testing, equipment testing on low and high voltage, control over heat, speed, and more.

However in order to purchase the right variac, it is critical that you know the amp usage by your electronic device. It is always best to be conservative otherwise you risk destroying the variac and it can be very dangerous. For example, if your device requires 5 amp, buy the variac with up to 10 amp. A rating of 300VA means that at 100volt, the unit can sustain at maximum 3amp. If at 120 volt the unit can sustain at 2.5amp
