Drive module for HVAC — 1.5 kW, 4 A, BACnet
The ABB 3AXD50000275458 is an ACH480-04-04A1-4 LV AC drive module built for HVAC applications. It delivers 1.5 kW normal-use output at 4 A from a 380–480 V three-phase supply, with a 2.8 kV·A apparent power rating. The module includes the control unit and carries an IE2 efficiency level. Communication is via BACnet; there is no industrial Ethernet interface. The drive has 2 analog inputs, 2 analog outputs, and 6 digital inputs / 3 digital outputs.
Duty ratings and UL derating
Normal-use output is 1.5 kW at 4 A (IEC). Heavy-duty use delivers 1.1 kW at 3.3 A; light-overload use holds 1.5 kW at 3.8 A. UL-listed normal-use current is 3.5 A, heavy-duty 3.0 A, light-overload 3.5 A.
Module-mount form factor in R1 frame. Standby loss is 15 W; power consumption during normal use is 62 W. Sound level is 63.1 dB(A). The drive includes a lithium coin cell (CR2032, 220 mAh, 3 V) for backup. No industrial Ethernet interface — BACnet only, so plan the fieldbus gateway accordingly.
