Schneider Electric ATV312HU15N4 Variable Frequency Drive – Altivar 312 Series
When a variable frequency drive fails on the production floor, the consequences are immediate and costly: motors run at fixed speed, energy consumption spikes, mechanical stress accelerates wear, and process control is lost entirely. Conveyor lines halt, pump systems lose pressure regulation, and HVAC systems revert to on/off cycling — all while downtime costs accumulate by the minute. The Schneider Electric ATV312HU15N4 is engineered to eliminate this vulnerability, delivering precise motor speed control that keeps critical industrial processes running with maximum efficiency and reliability.
The ATV312HU15N4 occupies a pivotal position within the Altivar 312 series — Schneider Electric’s purpose-built drive platform for simple machine applications requiring robust performance in a compact footprint. Rated at 1.5kW (2HP) for three-phase 380–480V supply networks, this drive is one of the most widely deployed units in the ATV312 lineup across global manufacturing, water treatment, and building automation markets. Its combination of integrated EMC filtering, embedded Modbus RTU communication, and a simplified commissioning interface has made it a benchmark product in the sub-2kW industrial drive segment worldwide.

Frequently Asked Questions
Q: What is the difference between ATV312HU15N4 and ATV312HU15M3?
A: The ATV312HU15N4 is designed for three-phase 380–480V supply networks, while the ATV312HU15M3 operates on single-phase or three-phase 200–240V networks. Both deliver 1.5kW output power but are not interchangeable due to different input voltage requirements.
Q: Does the ATV312HU15N4 include a built-in EMC filter?
A: Yes. The ATV312HU15N4 incorporates an integrated Class A EMC filter, making it suitable for industrial environments without requiring an external filter for standard installations.
Q: Can this drive be controlled via PLC Modbus RTU?
A: Yes. The drive features a native RS-485 Modbus RTU port. It can be fully controlled (speed reference, run/stop, fault reset) and monitored via any compatible Modbus master, including Schneider Modicon PLCs and third-party controllers.
Q: What motor types are compatible with the ATV312HU15N4?
A: The drive is optimized for standard IEC asynchronous (induction) motors rated at 1.5kW, 380–480V, 3-phase. It is not designed for permanent magnet synchronous motors (PMSM) without additional configuration.
Q: Is the ATV312HU15N4 still in production?
