Will a 3-phase power supply still operate normally if there is only 2-phase power input?

Delta's 3-phase power supply allows for a wide range of input operating voltages.

This range from 320Vac to 575Vac with a nominal range of 400Vac to 500Vac.

To operate normally, the power supply will require a minimum 2-phase input voltage of 360Vac unlike a minimum 320Vac for a 3-phase power supply. For higher powered models such as the 480W and above, the min 2-phase input voltage is 380Vac. In case the minimum input is lower than this, there will be a power derating.
