VFD32AMH43ANSAA | Delta | Variateurs de moteur AC à vitesse variable

Description

Designed to deliver precise velocity and torque control for industrial induction motors, the Delta Electronics VFD32AMH43ANSAA operates as a high-performance variable speed AC motor drive and frequency converter. Built on Delta's robust Frame E platform, this drive features a flexible dual-rating design that supports both Heavy Duty (HD) and Normal Duty (ND) operation profiles to optimize energy efficiency and performance across diverse application demands.

The unit accepts a wide 3-phase input voltage tolerance and processes high-efficiency carrier frequencies, minimizing motor noise while maintaining thermal efficiency. With its compact IP20 enclosure, the VFD32AMH43ANSAA integrates seamlessly into standard industrial control cabinets, providing critical motor speed regulation and protection functions for modern automated systems.

Features

• Dual-Duty Rating: Optimized to support either Heavy Duty (15 kW / 20 HP) or Normal Duty operation profiles depending on load dynamics.
• Frame E Design: Compact footprints and optimized structural design for space-restricted industrial enclosures.
• Flexible Carrier Frequency: Adjustable range from 2 to 15 kHz allows fine-tuning for low motor noise and reduced electromagnetic interference.
• Wide Operating Range: Supports input voltage tolerances of -15% to +10% with a frequency tolerance of 47 to 63 Hz to ensure stability under fluctuating grid conditions.
• Optional EMC Integration: Accommodates optional EMC filters to meet rigorous industrial noise emission standards.

Applications

• Heavy-duty conveyor systems and material handling.
• Industrial fan, blower, and ventilation control systems.
• Centrifugal and positive displacement pumps.
• Extruder, mixer, and agitator speed regulation.
• Metal processing and machinery tool axes.

Technical Specifications

Installation Guidelines

• Mounting Alignment: Mount the Frame E drive vertically on a flat, non-flammable surface to ensure unobstructed convective airflow.
• Clearance Spacing: Maintain the manufacturer-recommended clearance spaces above, below, and on the sides of the drive for optimal heat dissipation.
• Grounding Requirements: Securely ground the drive's protective earth (PE) terminal to the primary system ground bus to minimize noise and prevent electric shock risks.
• Shielding & Cabling: Use shielded cables for motor connections and control wiring. Keep control cables routed separately from power and motor cables to prevent electromagnetic coupling.
