Features:

  • 380V to 480V AC Three-Phase Power Conversion for 37kW HVAC Motors
  • Integrated C2/C3 EMC Filter with Low Harmonic Distortion Technology
  • Supports Multiple Control Modes and Building Automation Communication Protocols
The Schneider Electric ATV212HD37N4 operates as a dedicated variable speed drive within the Altivar 212 series, providing precise motor control for HVAC fluid management applications. It continuously converts incoming three-phase AC power (380-480 VAC, 50/60 Hz) to adjustable frequency output (0.5-200 Hz) and distributes controlled power to 37kW asynchronous motors to support steady state operation of fans, pumps, and compressors. Seamless speed regulation is standard with the ATV212HD37N4, however using the built-in RJ45 port or optional communication cards will allow seamless integration with BACnet, Metasys N2, or Apogee P1 FLN building automation systems. The ATV212HD37N4 has made improvements in several areas over previous drive designs in addition to incorporating low harmonic technology and built-in C2/C3 EMC filtering within the Altivar 212 range.

The ATV212HD37N4 provides essential motor control functions common to the entire HVAC system, and is a critical component of the fluid management path, directly affecting the proper, normal operation of the overall climate control system. One ATV212HD37N4 variable speed drive is required per motor depending on the desired control level.

For advanced control applications, the HVAC system requires the ATV212HD37N4 to be configured with appropriate control modes and communication interfaces. In addition to standard V/f control operation, the ATV212HD37N4 also performs automatic energy optimization and sleep/wake functions. The ATV212HD37N4 control configuration executes motor management using the internal control algorithms specified in the drive firmware. Using this method, the ATV212HD37N4 continually monitors the health of motor parameters. If the system detects that the motor load is no longer requiring full output (outside configured speed/torque levels), it will automatically transfer to sleep mode or secondary control profiles and log the operational event.

The ATV212HD37N4 Schneider Electric Variable Speed Drive may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
