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..

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..

- Enclosed, non-isolated, Adjustable transformer, with Output Volt Meter.OnOff Power SwitchLighted,5A fuse power cord.. - Over-voltage protection, the use of more security.Contact voltage transformer, wide voltage range 0-130V.. - Built-in copper coil, material quality, more secure and durable.High efficiency and with no waveform distortion.. - Suit for home coffee roasting,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 5 amp rating may have over 10 amp surge, and you will need 10 amp transformer..

During normal operation, the regulator should be checked regularly by charcoal brush and make sure that the brush and contact parts wont be more than the wide of two wires.. Check the insulation resistance regularly, the insulation resistance between coil and base shouldnt be less than 2mm.. Please connect the ground line to regulator case. After operation, turn the hand wheel pointed to zero place and cut off the power.. NoteThe output voltage is lower,the output power is lower,the load power is lower..
