The Schneider ATV610D18N4 is a compact VFD from the Easy Altivar 610 range, engineered for 18.5kW (25HP) three-phase motor control in pumps, fans, compressors, and conveyors—delivering soft starts, precise speed/torque, and energy savings for industrial automation.
Built for dependable plant operation, the ATV610D18N4 provides 18.5kW (ND) / 15kW (HD) with continuous output currents of 39.2A (ND, 4kHz) and 31.7A (HD, 4kHz), plus line currents up to 37.2A at 380V (ND). The cabinet-mount design is IP20 and compact—H 495mm (580mm with EMC plate), W 211mm, D 232mm—at 13.5kg, suiting space-constrained panels. Engineers get fine control via an output frequency of 0.1…500Hz, 2…12kHz switching, 16 preset speeds, and independently adjustable ramps (0.01…9000s). I/O is sensor-ready: 3 analog inputs (0–10V / 0–20mA, including temperature/level probes), 2 analog outputs, 6 digital inputs (pulse to 30kHz), and 3 relay outputs (3A, 100k cycles) for interlocks/alarms. A 2-wire RS-485 Modbus RTU interface with RJ45 ensures seamless PLC/SCADA integration and diagnostics.
Trusted in harsh environments, this Schneider drive operates from −15…60°C and up to 95% RH (IEC60068-2-3), includes an integrated EMC filter (IEC61800-3 CatC3), and maintains a low 65dB noise profile. Comprehensive protections—thermal (motor/drive), overcurrent, short-circuit, over/undervoltage, phase loss, overspeed, and DC-bus events—safeguard uptime while DC-injection braking shortens stops on critical lines. For wiring ranges (control 0.5…1.5mm², power 10…16;mm²) and quick commissioning, the ATV610D18N4 simplifies standardization across utilities, water handling, HVAC, and process plants.
