Line current draws 3.463 A at 380 V normal duty, 2.7 A at 480 V normal duty; heavy duty pulls 2 A at 380 V and 1.7 A at 480 V. Integrated Class C2 EMC filter is onboard, so no external filter needed for most commercial installations. Safety function is STO rated SIL 3 / PL e. ## Integration notes Wall-mount only, vertical position. Dimensions are 247 mm deep, 189 mm wide, 375 mm tall. Control circuit requires an external 24 V DC supply (19...30 V). ## Functions and protection Built-in functions include fire mode, forced fire mode, PID controller with 3 additional PID, damper control, underload detection for broken belt, scroll compressor management, skipped frequencies, catch on the fly, power monitoring, and cybersecure firmware update. Protection covers motor thermal overload, STO, motor phase loss, overspeed, drive overheating, output short-circuit, DC bus overvoltage, line supply over/undervoltage, and control circuit break.","metaTitle":"Schneider ATH650U15N4 Altivar HVAC Drive, 1.5 kW, 380-480 V","metaDescription":"Schneider ATH650U15N4 Altivar HVAC drive, 1.5 kW normal duty, 380-480 V, integrated C2 EMC filter, STO SIL 3, active production.
