ATV28EU18N4 belongs to Schneider Altivar28 inverter family, DIN rail or cabinet wall mounting, protection class IP20. Input voltage 3-phase AC380~480V, 50/60Hz, output rated 1.5kW for standard 3-phase induction motor. It adopts V/F control mode, output frequency range 0~400Hz.

It is equipped with configurable digital inputs, relay alarm output and analog 0~10V / 4~20mA I/O for speed setpoint and feedback. Built-in basic protection functions including overcurrent, overload, overvoltage, undervoltage, overheat and motor short-circuit protection. Front panel keypad and LED indicators support parameter setting and fast on-site fault diagnosis. Optional RS485 communication module for Modbus network connection. Operating temperature range 0~50℃.

ATV28EU18N4 is obsolete Schneider VFD spare part. Many legacy factory equipment still run Altivar28 drive systems. When the original drive fails, replacement with identical ATV28EU18N4 can reuse power wiring, motor cable and saved parameter settings. Technicians install the drive, configure motor nameplate parameters and test start-stop & speed regulation, so motor speed control system resumes operation and reduces downtime.

Before shipment, every ATV28EU18N4 undergoes comprehensive functional inspection including power-on self-test, I/O terminal test, output waveform check and insulation resistance test. All products come with 12-month warranty. Our automation technical team provides remote support for installation, wiring guidance, parameter setting and fault diagnosis. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, ATV28EU18N4 is reliable spare general-purpose inverter for legacy Schneider Altivar28 motor control systems. It restores adjustable speed control for induction motors, extends service life of automation assets and avoids whole machine renovation.
