EL-W Series VFD (1-Phase Input)

About the Delta EL-W Series VFD (Single-Phase Input)

The Delta EL-W Series is a compact variable frequency drive (VFD) designed for applications where a three-phase motor needs to be operated from a single-phase 230V supply. The single-phase EL-W range covers motor applications from small fractional-kilowatt drives through 2.2 kW, depending on the model.

Key Features

• Single-phase 200–240V input with three-phase motor output, depending on model
• Vector-control capability for improved motor speed and torque control
• Built-in PID control for applications requiring feedback-based process control
• Multi-speed operation and multiple control methods
• Compact IP20 design suitable for space-constrained control panels
• RS-485 Modbus communication for integration with control systems

Typical Applications

The single-phase EL-W is suitable for small pumps, conveyors, material-handling equipment, packaging machinery, woodworking equipment, and other general-purpose motor-control applications where only single-phase power is available.

Available Power Range

The Delta EL-W single-phase range is available from 0.2 kW (0.25 HP) to 2.2 kW (3 HP), depending on the model. Always select the VFD according to the motor rated current, application duty and the manufacturers sizing recommendations.

Why Choose the EL-W Series?

The EL-W provides a compact solution for controlling three-phase motors where a suitable single-phase supply is available. Its integrated control and communication functions make it suitable for a range of small industrial and OEM applications.
