Product Overview

The Schneider Electric ATV212HD22N4S is a variable speed drive from the Altivar 212 series, specifically designed to provide superior motor control for three phase asynchronous motors. With a power rating of 22 kW (30 hp) and a supply voltage range of 380 to 480 VAC three phase, this drive is optimized for pumps, fans, and HVAC applications where energy efficiency and operational reliability are paramount. The ATV212 series combines advanced motor control algorithms with a compact, slim form factor, making it an ideal choice for original equipment manufacturers (OEMs) and system integrators seeking to reduce cabinet space while maintaining high performance.

Equipped with a built in EMC filter of Class C2, the ATV212HD22N4S meets stringent electromagnetic compatibility standards without requiring external filtering components, reducing installation complexity and material costs. Its IP21 protection rating ensures the drive is safeguarded against solid objects larger than 12.5 mm and dripping water, making it suitable for installation in indoor industrial environments where moderate exposure to dust and moisture is expected.

Technical Specifications

Key Features

• Class C2 integrated EMC filter ensures compliance with European EMC directives and reduces installation costs and panel space.

• Multiple motor control profiles including Voltage/Frequency ratio (2 point, 5 point, energy saving quadratic U/f), flux vector control without sensor, and automatic IR compensation for optimized torque performance across varying loads.

• Built in adjustable PI regulator for direct closed loop control of process variables such as pressure, flow, or temperature without requiring external controllers.

• Smart protection features including motor slip compensation and automatic voltage regulation to maintain stable output under fluctuating line conditions.

• Flexible communication options compatible with building management systems and industrial networks via optional communication modules.

• Slim housing design reducing panel depth requirements and simplifying installation in retrofit projects or space constrained enclosures.

Applications

The Altivar 212 series, exemplified by the ATV212HD22N4S, is purpose built for variable torque applications where energy savings are a primary driver. Typical installations include centrifugal pumps in water treatment facilities, supply and exhaust fans in commercial HVAC systems, cooling tower fans, air handling units, and industrial compressors. In building automation, this drive integrates seamlessly with BMS protocols to enable demand based ventilation and pumping, significantly reducing electrical consumption compared to fixed speed operation.

In industrial manufacturing environments, the ATV212HD22N4S controls conveyors, mixers, and agitators where soft starting and adjustable speed profiles improve process consistency and reduce mechanical wear. Its rugged IP21 construction and wide ambient temperature tolerance allow installation in machine rooms, electrical closets, and factory floors without additional enclosures for clean, indoor conditions.
