Product details

The ATV950D45N4 is a 45 kW Altivar Process variable speed drive for asynchronous and synchronous motors, rated 88 A continuous at 4 kHz for normal duty, with a heavy-duty rating of 74.5 A at 4 kHz for 37 kW. IP55 enclosure and integrated EMC filter let it mount on the wall without a separate cabinet or filter in many process environments.

Compliance and sourcing posture

CE marked; complies with UL 508C, IEC 61800-3, IEC 61800-5-1, IEC 61508, and IEC 13849-1.

Wall-mount only, vertical ±10°. Power wiring via screw terminals accepting 35–50 mm² (AWG 3–1) for line, motor, and DC bus; control terminals for 0.5–1.5 mm². Option slots A, B, C accept communication modules — PROFIBUS DP, PROFINET, EtherCAT, CANopen, DeviceNet, Ethernet Powerlink — plus I/O extension and encoder interface modules. Braking chopper is standard; no external brake unit needed for dynamic braking. Internal supply for digital inputs and STO: 24 V DC (21–27 V); potentiometer reference: 10.5 V DC ±5% for 1–10 kΩ. Derate output current 1% per 100 m above 1000 m operating altitude. IP55 and resistance to chemical and dust pollution allow installation in humid or dusty areas without additional enclosure.

Frequently asked questions
