    Tips: What are the differences among a transformer, a voltage stabilizer and a voltage regulator?

    A transformer can control the unstable voltage in a certain voltage range and protect the equipment from being damaged. A voltage regulator converts a specific voltage to the needed voltage of an equipment, each equipment should be equipped with a voltage regulator to prevent from burning out equipment caused by excessive voltage change. A voltage stabilizer is used to stabilize the voltage. Generally, a voltage regulator is a kind of test equipment that can change the voltage, while a voltage stabilizer can only adjust the voltage in a certain range. The voltage regulator can adjust the high voltage, but can’t insulate it, while the transformer is generally used to isolate, such as the isolation transformer, the transformer can be used to step up or step down the voltage. A voltage stabilizer is just a way to stabilize the voltage.

    Existing reviews of 20 kVA Isolation Transformer, Single phase, 240V to 208V
    Purchased your 20 kVA isolation transformer.
    I purchased your 20 kVA isolation transformer 3 phase from 208V primary to 380V secondary (3phase   neutral   ground). We are currently using this transformer for a machine that pulls 7 kW and want to use another machine that pulls 8 kW. My question is, can we double lug, or pull two loads off the secondary side from this one transformer?

    Was this review helpful? Yes No (0/0)
    ATO Responded
    You can double lug, directly using the two devices, but pls make sure the power is not overloaded.
    Installation location of 20kVA isolation transformer
    Can your 20Kva isolation transformer be installed in the wall?
    From: Staley | Date: 27/05/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Yes, our isolation transformer can be installed on the wall if there will be a fixed mounting bracket.
