Variac, 500VA Variable Voltage Transformer,AC Auto Transformer | 5Amp Variac Transformer,110V Input 0-130V Output,Ideal for Household Industrial and Lab Voltage Testing

Enclosed, non-isolated, adjustable transformer with an output volt meter. Features an on/off power switch (with indicator light), a 5A fuse, and a power cord. - Over-voltage protection for improved safety. Contact voltage transformer with a broad voltage range (0-130V). - Constructed with a built-in copper coil for superior material quality, enhanced security, and long-lasting durability. High efficiency with no waveform distortion. - Appropriate for home coffee roasting, motor speed control, label printing machines, EE labs, testing for railroad switching, power supplies, satellite equipment, and telecommunication equipment.

Please note that most devices have a surge (when initially powered on) significantly higher than the operating amp rating. For example, a motor with a 5 amp rating may have a surge exceeding 10 amps, necessitating a 10 amp transformer
