What input voltage range does the Dynasty 280 accept?

The Dynasty 280 accepts input voltages between 208 and 575 VAC thanks to its Autoline circuitry, which automatically adapts to the supplied primary voltage. The actual input voltage must not drop below 188 VAC or rise above 632 VAC, or the unit may not operate to specification. No internal reconnection is required when switching between voltages.
