Technical specifications for
ATV312H037M2
ATV312H037M2 Schneider Electric variable speed drive
The ATV312H037M2 from the Altivar 312 range by Schneider Electric is a compact and robust variable speed drive, specifically designed for controlling asynchronous motors in simple machine applications. Built with a heat sink assembly, it ensures efficient thermal management, making it suitable for demanding industrial environments.
This model supports a motor power of 0.37 kW (0.5 hp) and operates on a single-phase supply voltage of 200–240 V (-15% to +10%) at a frequency of 50–60 Hz (±5%). It draws a line current of 5.3 A at 200 V and 4.4 A at 240 V, with a maximum apparent power of 1 kVA and power dissipation of 41 W at nominal load. The integrated EMC filter ensures compliance with industrial noise reduction standards.
The drive offers a wide speed range of 1 to 50, and supports an output frequency of 0–500 Hz. It is equipped with adjustable switching frequency from 2 to 16 kHz, with a nominal switching frequency of 4 kHz and continuous output current of 3.3 A at 4 kHz. It can handle transient overtorques of 170–200% of the nominal motor torque, making it reliable in heavy load start-up conditions.
For communication, it includes 1 RJ45 port supporting Modbus and CANopen protocols via RS485 physical interface. Local status indication is provided through a red LED for drive voltage and four 7-segment displays for CANopen status. The drive's analog input frequency resolution ranges from 0.1 to 100 Hz, and display resolution is 0.1 Hz, offering precise control and feedback.
Designed for vertical mounting with up to ±10° tolerance, the ATV312H037M2 has dimensions of 145 mm height, 72 mm width, and 132 mm depth, and a net weight of 1.5 kg. It meets CE marking standards, features a time constant of 5 ms for reference change, and is built with an insulation resistance of ≥ 500 mΩ at 500 V DC for 1 minute, ensuring durability and safety in operation.
With its compact design and powerful features, the ATV312H037M2 is an ideal solution for cost-effective, efficient motor control in a wide range of industrial machinery.
