Drive Frekuensi Variabel Schneider Altivar 21 ATV21WD37N4

Description

The ATV21WD37N4 is a Variable Frequency Drive (VFD) from the Altivar 21 series, engineered by Schneider Electric to provide high-capacity motor control for demanding industrial applications. This drive is rated for 37KW (50HP) operation at 480V and features an integrated EMC Class A filter to minimize electromagnetic interference in sensitive electrical environments. Enclosed in an IP54-rated housing, the ATV21WD37N4 provides protection against dust and water spray, making it suitable for direct installation in harsh plant-floor conditions. Measuring 88.00 x 28.40 x 34.30 cm, this robust drive is a key component for managing large-scale motor loads in pump, fan, and industrial processing systems.

Installation Guidelines

• Due to its 56kg weight, ensure the mounting surface is structurally reinforced to support the load of the drive.
• Maintain clear vertical orientation and verify that all IP54 seals are intact after installation to ensure environmental protection.
• Provide adequate ventilation space around the drive to allow for thermal dissipation, especially when operating near the 37KW capacity.
• Use appropriate cable glands for all power and control entries to maintain the IP54 integrity of the enclosure.
• Connect the chassis to a verified earth ground to ensure the effectiveness of the integrated Class A EMC filter.
• Perform a thorough inspection of all power terminals for secure connection and proper insulation before applying line voltage.
