Top 8 Best Variac

Secure quality materiel - Built-in copper coil, more secure and durable.High efficiency and with no waveform distortion.. Details - Enclosed, non-isolated, Adjustable transformer, with Output Volt Meter.OnOff Power SwitchLighted, 20A fuse power cord.. Perfect speed controller - The variable transformer is a great device for quality control testing, equipment testing on low and high voltage, control over heat, speed, and more. And because a transformer doesn't chop up the AC waveform like electronic speed controllers do, there's no noise, humming, etc.. Power Specifications - Max. 1800VA for continuous use , is also to prevent damage from the transformer itself and the appliance being used.Input Voltage AC 110V60Hz,Output Voltage AC 0-130V60Hz or 130-0V. Widely applications - Suit for home coffee roasting,Motor Speed control,Label Printing Machine,EE Labs,Test for Railroad Switching, Power Supplies, Satellite,Equipment,Telecommunication Equipment..

OnOff Power SwitchLighted,20A fuse power cord.. Enclosed, non-isolated, adjustable transformer, with Output Volt Meter.. Built-in copper coil, material quality, more secure and durable.. Contact voltage regulator, wide voltage range 0-130V.. Suit for Motor Speed control,Label Printing Machine,EE Labs,Test for Railroad Switching, Power Supplies, Satellite,Equipment,Telecommunication Equipment..

a variable AC input to a transformer input DC bridge rectifier to produce a variable output. The adjustable voltage transformers does not convert AC to DC. It requires an AC input and the output is also AC. Also, the unit will not affect the cycle rate from the power company. If your power system is providing 60Hz, the Variac auto transformer will not change that, the ouput will be an undistorted 60Hz. This unit is rated up to 20 Amps or 2KVA Peak 16A Continous.. Power 2000VA,Input voltage 110V, Input current 18A, Output voltage 0-130V, Rated output current 15.38A Continuous operation for 2 hours, 10A can work continuously. This variable transformer is the perfect speed controller. The speed is infinitely variable, and because a transformer doesn't chop up the AC waveform like electronic speed controllers do, there's no noise, humming, etc.. If you're planning on using this as an industrial or bench-top supply with heavy loads, I'd recommend examining the brushes and adjusting the spring pressure on the windings. This can improve performance by reducing brush-contact sparking. Otherwise, this device is ready to work right out of the box..

2000VA variable voltage regulator input voltage 110VAC 60Hz. It is a contact voltage regulator with wide voltage range 0-130V.. The autotransformer with a exquisite rotating handle,comfortable grip and flexible operation, easy to control output voltage what you need.. The auto transformer is built-in good quality material copper coil, and with thermal grid design is more easy let the machine cool, more secure and durable.. This 2KW autotransformer be widely used in motor speed control, label printing machine, EE labs, test for railroad switching, power supplies, satellite, equipment, telecommunication equipment.. Please note that most device have surge when first turn on much higher than operating amp rating. E.g, motor with 10 amp rating may have over 20 amp surge, and you will need 20 amp transformer..
