Schneider Electric Altivar 950 ATV950D18N4 Variable Frequency Drives

Description

The ATV950D18N4 is an Altivar 950 upright frequency converter engineered by Schneider Electric for demanding industrial motor control and process automation applications. This advanced variable frequency drive delivers a rated power output of 18.5 kW and operates within a supply voltage range of 400 to 480 V. Designed with an integrated brake chopper, it provides superior dynamic braking performance and energy management during rapid deceleration and frequent start-stop cycles. Housed in a robust IP55 rated enclosure, it offers excellent protection against dust and water jets, making it ideal for harsh or washdown plant environments. Typical industrial applications include centrifugal pumps, high-inertia fans, material handling conveyors, extruders, and heavy-duty industrial mixing machinery. It is fully compatible with standard Schneider Electric Altivar automation architectures and digital control networks.
