    30 kVA Isolation Transformer, single phase, 110V to 220V

    5 out of 5 based on 2 reviews | Write a review
    30 kVA isolation transformer is an automation single-phase distribution transformer, mainly step up 110V primary to 220V secondary voltage or step down 220V input to 110V output, it features low temperature rise and suits for industry service.
    Delivery date: 10-20 days

    The insulation class of this safety single phase 30kVA 110V to 220V isolation transformer has three grades to guarantee the security. Overload capacity allows more than 1.2 times rated load to work for up to 1 hour, which makes the single phase transformer harmless.

    Tips: Why using isolation transformer?

    1. Generally, ungrounded systems leads to fewer single-phase electric shocks. Due to that, grounding system should be transformed into ungrounded system by using isolation transformer in some specific situation. For example, if people fix a TV which connected to an isolation transformer, he can operate it at 220V voltage with no trouble in electricity. It is safe!
    2. For safety, isolation transformers are needed to supply ungrounded power to industry pick and place equipment, wave soldering machine, reflow controller, etc.
