Drive module for HVAC duty
The ABB 3AXD50000275502 is an ACH480-series low-voltage AC drive module built for HVAC applications. It delivers 7.5 kW normal-use output at 17 A from a 380-480 V three-phase supply, with heavy-duty rating of 5.5 kW / 12.6 A and light-overload rating of 7.5 kW / 16.2 A. The frame size is R3, IP20 enclosure, open type per NEMA. Communication is BACnet, with 2 analog inputs and 2 analog outputs. Digital I/O counts 6 inputs and 3 outputs. No industrial Ethernet interface is onboard. Standby loss is 25 W; full-load power consumption runs 259 W. Efficiency class is IE2. The module includes a control unit and a lithium coin cell (CR2032, 220 mAh) for backup.
No direct pin-compatible alternative is listed in the evidence; the ACH480 series is the current generation for HVAC duty.
Installation notes
Sound level is 65.8 dB(A). Input frequency range 47.5-63 Hz. UL output currents: normal use 14 A, heavy-duty 11.0 A, light-overload 14.0 A.
