It accepts a nominal input of 100...120 V AC single phase or 200...240 V AC phase-to-phase, making it flexible for different line voltages across facilities. A useful feature for motor or solenoid starting is the permissible temporary current boost of 1.5 x In for 4 seconds, giving headroom for inrush without oversizing the unit.
Input terminals accept single-phase N-L1 at 100-120 V AC or phase-to-phase L1-L2 at 200-240 V AC. The anti-harmonic filter handles low-frequency harmonic currents, which is typical for switch-mode supplies feeding DC loads.
