22 kW HVAC drive with STO and BACnet/IP
The ATH230D22N4 is a 22 kW Altivar HVAC ATH200 drive for 3-phase 480 V fan and pump loads. Rated line current is 64.6 A at 380 V and 49.4 A at 500 V, with 42.8 kVA apparent power at 500 V. This is the standard version — no coating or extended I/O — meant for clean indoor cabinet mounting. It carries integrated STO (Safe Torque Off) at SIL 3 / PL e, so it can serve in safety-rated applications without an external safety relay for the stop function. The integrated EMC filter meets IEC 61800-3 environment 1 category C2 and environment 2 category C3, covering both residential and industrial second-environment installations.
Built for fan and pump duty
The drive includes fire mode, run-permissive, PID controller, damper control, and underload detection for broken belt — all standard. The BACnet/IP communication module is an option card slot; the base unit has a 2-wire RS-485 physical interface supporting Modbus serial and BACnet MS/TP at 38.4 or 76.8 kbit/s. Cabinet mount, vertical +/- 10 degrees. Operating altitude is 1000 to 3000 m with 1% current derating per 100 m above 1000 m. Pollution degree 2, relative humidity 5-95% non-condensing. Noise level is 64 dB — expect audible fan noise in a quiet machine room.
