Product details

The ATH630U22N4Z is a 2.2 kW normal-duty / 1.5 kW heavy-duty VFD from the Altivar HVAC ATH600 series, sized for a 3 hp motor on 380-480 V three-phase supply. Line current pulls 4.837 A at 380 V normal duty, 3.8 A at 480 V normal duty; heavy-duty figures are 3.5 A and 2.8 A respectively. The integrated Class C2 EMC filter covers most commercial installations without an external box. The control circuit needs an external 24 V DC supply (19...30 V); the drive generates its own 24 V for digital inputs and STO internally.

Three relay outputs are built in: R1 offers one NO and one NC contact; R2 and R3 each provide one NO contact, all rated for 100,000 cycles. Analog inputs AI1-AI3 carry ±1.5 % accuracy over a 60 °C swing; analog outputs AQ1-AQ2 hold ±1 %.
