- 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..

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..

High Reliability ProtectionThe lab power supply is equipped with OCPOVPOTP protection function. When the actual voltagecurrent value exceeds the setting OVPOCP value, the adjustable dc power supply will initiate self-protection and turn off the output. These protection functions ensure safety during testing and extend the life of the equipment. The shell of dc power supply is light brown, photo color and the actual color has a color difference.. LED Display and FunctionThe ac-dc adjustable power supplies usually displays the actual voltage and current values. When you press 'shift' twice, the settings will be displayed for three seconds. Key lock function can prevent error operation by unauthorized person and the lab power supply has CVCC mode automatic conversion function.. Simple and PracticalThe single output lab bench power supply does not have programmable functions, so its operation isnt complicated. ITECH IT6721 adjustable power supply can meet more testing needs than conventional lab power supplies with fixed output ratings due to its widest voltage and current utilization. The variable dc power supply can provide any VoltAmp combination within the rated power, so you an cut down on the number of power supplies required and free up valuable bench space.. Measurement and PackageOutput Voltage 060V, Output Current 08A, Power 0180W, Resolution 0.01V0.001A, Accuracy 0.0510mV0.35mA. 100 Customer SatisfactionThe laboratory power supply has undergone multiple quality tests and calibration before leaving the factory, we guarantee its quality.
