The Schneider Electric ATV21HD37N4 variable speed drive serves a crucial role in modern automation and motor control applications. Rated at 37 kW (50 HP), this unit operates efficiently on a 3-phase power supply within a voltage range of 380 to 480 volts, accommodating variations with tolerances of -15% to +10%. The drive supports operational frequencies of 50 to 60 Hz, featuring a tolerance of ±5%
For speed management, it offers a range from 1 to 10, with a customizable switching frequency of 6 to 16 kHz, which can adjust to 8 to 16 kHz under specific derating conditions. Enhanced performance is facilitated by an integrated Class A EMC filter, ensuring compliance with electromagnetic compatibility standards. The protection ratings are IP20 for the upper part without a blanking plate and IP21 overall, safeguarding the drive from dust and incidental water exposure.
Communication protocols such as Modbus are included, with additional options available for APOGEE FLN, BACnet, LonWorks, and METASYS N2, providing versatility in connectivity for integration into existing systems. The drive is equipped with 2 analog inputs, 1 analog output, and 2 discrete outputs for comprehensive control capabilities.
The torque accuracy is specified within ±15% of the motor's nominal torque, with the ability to handle transient overtorque situations of up to 120% of nominal torque for a duration of 60 seconds. Dimensions for the ATV21HD37N4 are 21.65 inches in height, 9.45 inches in width, and 4.45 inches in depth, making it a compact solution that fits well in many industrial installations.
