Delta VFD150E43A VFD-E Variable Frequency Drive

Description

Designed for industrial process automation and precision motor speed control, the VFD150E43A is a sensorless vector control variable frequency drive within the Delta Electronics VFD-E series. This highly modular AC motor drive supports an applicable motor capacity of up to 15 kW (20 HP) and operates on a 460V three-phase input. Built with integrated PLC functionality and supporting various fieldbus options via optional extension cards, it delivers robust torque performance and reliable operation across automated manufacturing environments.

Features

• Modular Architecture: Flexible design accommodates various extension cards, including I/O cards, relay cards, and communication modules.
• Integrated PLC Function: Built-in ladder logic capability with up to 500 steps minimizes the need for external controllers in simple sequence tasks.
• Control Modes: Supports both V/f (Voltage-to-Frequency) control and high-performance Sensorless Vector Control (SVC).
• RFI Filter: Integrated radio frequency interference filter reduces electromagnetic emissions.
• Shared DC Bus: Allows parallel connection of multiple drives to share regenerative energy and improve efficiency.
• Comprehensive Protection: Built-in safeguards against overcurrent, overvoltage, undervoltage, overheating, overload, and ground faults.

Applications

• Conveyor systems and material handling machinery.
• Centrifugal pumps, industrial fans, and HVAC equipment.
• Extrusion lines and plastic injection molding auxiliary systems.
• Textile machinery and mechanical packaging lines.
