The CliQ II series models are designed for 3 phase input voltage, can start up at very low input voltage, and do not require any power de-rating across the entire input voltage range from 320 to 575 VAC. The advantage of CliQ’s 3 Phase input is that during a loss of one input phase, the unit is still able to deliver 100% output power at a minimum input voltage of 360 VAC. Competitor A can only start up at a relatively higher input voltage for 3 phase input and can only support a lower load when one phase is lost. Competitor D has power de-rating of 75% rated load during the loss of one phase and is much more expensive.
