The ABB 3AXD50001109813 is an ACH580-01 wall-mounted HVAC drive rated 18.5 kW normal-use output at 38 A on 380–415 V three-phase supply. Heavy-duty use drops to 15 kW / 31.6 A for tougher load profiles like fans or pumps with high starting torque. Light-overload use (18.5 kW / 36.1 A) mirrors the normal-use power but with a slightly lower current — useful when the motor is oversized relative to the driven load. The drive includes the control unit, so it's ready for commissioning out of the box — no separate controller module to order. Power factor sits at 0.98, typical for an active-front-end or well-tuned VFD, meaning the line draw stays clean and the upstream transformer or generator doesn't need oversizing for reactive current. Standby loss is 16 W — low enough that the drive can stay powered 24/7 in a mechanical room without wasting significant energy. The BACnet communication protocol (MS/TP or IP, depending on the variant) is the standard for building automation integration, so it talks directly to the BMS without a gateway.
IP66 and NEMA Type 4X enclosure means the drive is dust-tight and protected against hose-directed water — suitable for outdoor installation, washdown areas, or coastal environments where corrosion resistance matters. Wall-mounted form factor keeps it off the floor and out of standing water; plan for gland-plate entry on the bottom to maintain the seal. Maximum ambient temperature is 40 °C — if the enclosure or mechanical room runs hotter, derate the output current per the drive's thermal curve (not provided here, but standard practice). The lithium coin cell (CR2032, 220 mAh) backs up the real-time clock and parameter storage; it's replaceable from the front without pulling the drive.
Two analog inputs and two analog outputs handle pressure transducers, temperature sensors, or speed-reference signals. Six digital inputs and three digital outputs cover start/stop, fault reset, and status feedback — enough for a basic HVAC zone controller without an external PLC. No onboard industrial Ethernet port; BACnet runs over the serial RS-485 connection.
