Beleeb 20Amp Variable Transformer Auto AC Voltage Regulator Power Supply, 2000VA Max, 0~130 Volt Output
Key features
- •a variable AC input to a transformer input DC bridge rectifier to produce a variable output
- •It is an incredibly affordable isolated variac for equipment testing.
- •Max. 2000VA,Input Voltage: AC 110V/60Hz,Output Voltage: AC 0-130V/60Hz
- •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.

It brings up electronics slowly like my SB-220 ensuring no major problems within what I test.
Better option for external fan speed contol

Picked up this unit to control the speed of a ducking fan. While the speed control options from the manufacture of the fan introduce a hum to it, this one does not. Complete control of the fan speed by turning a dial with no hum occurring from the fan.
Note: While the product description states the item weight for this is 0.634 ounces, it weighs in at 7.5 lbs. Plan accordingly if your mounting it somewhere other than on a table.

I'm using the Beleeb 20 amp variable autotransformer to adjust my home's voltage for use with 100V Japanese electronics (Denon 100W amp and CD player.) House voltage at plug measures 120.0V, and with variac dial set to "90"(as per picture above,) the built-in voltmeter needle lies directly above the first "1" of the "110" marking (as per second picture above.) At such setting, Klein multimeter measures 99.9V out of both plugs on the variac. I would advise you to measure your home's actual voltage output at plugs, and confirm variable autotransformer settings with voltage output measured at each of its plugs. It seems to work as advertised, has a sturdy build, good tight feel to its knob, and, best of all, I do not have any new noise picked up by my stereo equipment downstream from the Beleeb unit.
Excellent value for the price.

Dial markings are referenced to a specific input line voltage. Yours may be different. If so you may need to recalibrate those markings with tape or label maker to agree with the actual output voltage at your input line voltage. However, while not specified or high resolution, the metered output accuracy is useable for many applications. Again, if in doubt calibrate the internal voltmeter with an external meter. Several spare fuses are included.
