ACUPWR Tru-Watts™ Refrigeration/Freezer/Cooler Device Transformers Versus Regular Transformers
Can I Use Any Voltage Transformer for My Refrigerator, Freezer, or Cooler Appliance?
The fact that this article exists should indicate the answer: No.
Refrigerators and cooling equipment are beholden to another, lesser-known factor in the electrical equation: AC line frequency. As defined in our blog article AC Line Frequency Explained, "AC power moves in sine wave-like fashion, alternating between positive and negative poles. Each positive-to-negative cycle finds electrons moving back and forth, positive (+) and negative (-) at the rate of 60 or 50 cycles per second, as measured in Hertz (Hz). Countries with 110-120 voltage have an AC frequency of 60 Hz, while most 220-240-volt countries have 50 Hz of AC. These frequency cycles create electrical heat or power dissipation, and if there is enough current (amps) and force (voltage) produced to meet the demands of an electrical device, that device will work."
With appliances such as refrigerators, wine coolers, freezers, and washers/dryers, there's an "X" factor that comes via the dependence on large motors that make these devices work. Motors built for 50 Hz electricity must be used with 50 Hz electricity. The same is true for 60 Hz motors. When used with the incorrect AC frequency they will perform inefficiently and eventually burn out along with the appliance's electronics. For example, using a refrigerator rated for 60 Hz through a 50 Hz electrical line will result in the motor running faster and less efficiently. The opposite holds true when using a 50 Hz motor with 60 Hz electricity.
ACUPWR Tru-Watts™ AUC and ADC models are specially designed for use with large motors and appliances that use them. They convert voltage from 110-120 volts to 220-240 volts and from 220-240 volts to 110-120 volts, respectively. Uniquely the AC frequency dilemma is resolved by the AUC and ADC models supplying additional or reduced power, respectively, that allows large motors to turn at the precise revolutions per minute (RPMs) that they were intended for. The motor behaves as it would if the AC frequency was precise, thus preventing inefficient operation and burnout.
When you’re ready to buy a refrigerator voltage transformer, ACUPWR builds the best available, manufactured here in the USA using premium components and build quality.
When searching for right refrigeration voltage transformer that will match the wattage requirement of your appliance, there’s a basic rule you can keep in mind: The bigger your refrigerator as measured by cubic feet of interior space, the more wattage the unit will require.
