Schneider Electric ATV212HD22N4S Altivar 212 Variable Frequency Drive

Description

The ATV212HD22N4S is a Variable Frequency Drive (VFD) from the Altivar 212 series, specifically engineered for HVAC and pump control applications. This drive provides precise speed and torque regulation for three-phase asynchronous motors, supporting a nominal power rating of 22 kW (30 HP) and a rated current of 43.5 A. It operates on a 3-phase supply voltage ranging from 380 V to 480 V AC.

Equipped with an integrated EMC filter (Category 2 or 3 compatible), this drive is designed to reduce electromagnetic emissions, ensuring compliance in standard industrial and commercial building environments. With an IP21 ingress protection rating, it provides reliable defense against solid objects larger than 12.5 mm. Although now classified as an Obsolete product, the Altivar 212 remains a trusted solution for managing fluid handling and ventilation systems in existing infrastructure.

Installation Guidelines

• Mounting: Mount the drive vertically on a wall or within an electrical cabinet. Leave at least 10 cm of clearance above and below the unit to prevent overheating during operation.
• Wiring: Connect the 3-phase AC power to the input terminals and the motor leads to the drive output. Use shielded motor cables to maximize the effectiveness of the integrated EMC filter.
• Environment: Ensure the ambient air temperature is within the manufacturer's specified range and that the environment is free from corrosive gases or excessive conductive dust.
• Grounding: Securely connect the drive's ground terminal to the system's protective earth to ensure safe operation and mitigate electrical noise.
