European isolation tranformer, this model does not comply with ABYC standard 188.8.131.52 regarding shield fault current but complies with appropriate European standards Accepts 50 or 60 Hz inputs in 120 or 230 volt configurations and can be used as a step up or step down transformer as well as a straight through isolation transformer. This model automatically detects the input voltage and adjusts the transformer taps as needed to output the pre-selected output voltage. 3600 Watt Auto 115/230 V This model will automatically switch to 115 V or 230 V supply, depending on input voltage. Supply 88 V – 130 V: switches to 115 V supply Supply 185 – 250 V: switches to 230 V supply
Yes the input voltage is automatically sensed by the transformer and it adjusts automatically to 120 or 230 volts. The user gets to preset the output voltage which does not vary once set, regardless which input voltage is supplied.
