Beleeb 20Amp Variable Transformer Auto AC Voltage Regulator Power Supply, 2000VA Max, 0~130 Volt Output

  • 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, 003c10A 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..
