Detailed Series Breakdown

Delta EL Series

The Delta EL series is an entry-level VFD designed for basic variable torque loads such as pumps and fans. It supports V/F control and is available in single-phase and three-phase input versions. The power range is 0.2kW to 7.5kW. It is a cost-effective solution for simple speed control applications where high precision is not required.

For input arrangements outside the manufacturer's stated rating, confirm the permitted derating with the relevant model manual. The EL series does not include built-in EMC filters as standard, but external filters can be added if needed. It is ideal for small water pumps, exhaust fans, and small conveyors in industries like agriculture, HVAC, and small-scale manufacturing.

Delta EL-W Series

The EL-W series is an enhanced version of the EL series, adding a built-in PLC and PID control functionality. This makes it particularly suitable for water pumping and HVAC applications where closed-loop control is beneficial. Available with EMC-compliant configurations depending on model and variant.

Power range is 0.2kW to 7.5kW, with single-phase and three-phase input options. The EL-W series can achieve energy savings of 20–60% for variable torque loads such as pumps and fans when operated below full speed. It is a popular choice for water supply systems, booster pumps, and cooling tower fans in Indian industries.

Delta VFD-E Series

The VFD-E series is a mid-range drive offering sensorless vector control, built-in PLC, and RS-485 communication. It covers a power range of 0.2kW to 22kW with three-phase input (230V or 460V). This series is suitable for general industrial machinery such as conveyors, mixers, and compressors.

The VFD-E series (EOL — MS300 recommended) provides good torque performance at low speeds and is often used in packaging machines, textile machines, and material handling systems. It supports Modbus RTU and, where applicable, optional communication cards for additional protocols. For applications requiring higher precision, the MH300 or VP3000 series may be more appropriate.

Delta ME300 Series

The ME300 series is a compact, budget-friendly drive designed for OEMs and panel builders. It offers sensorless vector control in a small footprint, with power range 0.2kW to 7.5kW. Available in single-phase and three-phase input versions.

The ME300 is ideal for simple machinery like small packaging machines, labeling machines, and small conveyors. It features easy parameter setting via a built-in keypad or software. For input arrangements outside the manufacturer's stated rating, confirm the permitted derating with the relevant model manual. It is a cost-effective choice for high-volume OEM applications.

Delta MS300 Series

The MS300 series is a compact, general-purpose drive with sensorless vector control and a built-in brake chopper. Power range is 0.2kW to 22kW with three-phase input (230V or 460V). It is suitable for a wide range of industrial applications including conveyors, textile machines, and packaging machines.

The MS300 series offers good torque performance and is easy to install and configure. It supports multiple communication options including Modbus RTU and CANopen. For applications requiring closed-loop control, consider the MH300 series. The MS300 is a popular choice for panel builders and machine manufacturers in India.

Delta MH300 Series

The MH300 series is a high-performance drive supporting sensorless vector control and optional closed-loop vector control with encoder feedback. It achieves up to ±0.01% speed regulation in closed-loop mode. Power range is 0.75 kW to 55 kW with three-phase input (230V or 460V).

This series is designed for high-precision applications such as packaging machines, textile machines, and winding machines. It offers 150% overload for 60 seconds and 200% for 3 seconds. The MH300 is ideal for applications requiring precise speed and torque control, such as printing presses and extrusion lines.

Delta VP3000 Series

The VP3000 series is designed for fluid-machinery applications such as pumps, fans, HVAC, chillers, and water-treatment systems. It covers a wide power range from 0.75kW to 630kW with three-phase input (230V, 460V, or 690V). It features high-performance vector control, 200% overload for 3 seconds, and a built-in brake unit.

The VP3000 is suitable for demanding applications like compressors, mixers, textile machines, and packaging machines. It supports Modbus RTU and optional communication cards including EtherCAT, PROFINET, and Modbus TCP. This series is often used in large industrial plants, mining, and material handling systems in India.

How to Choose the Right Delta VFD Series

Selecting the right Delta VFD series depends on three key factors: power requirement, control complexity, and budget. For simple fan and pump applications with power up to 7.5kW, the EL or EL-W series offers the best value. For general industrial machinery up to 22kW, the VFD-E or MS300 series provides sensorless vector control and good performance.

For high-precision applications requiring closed-loop control, the MH300 series is the right choice. For heavy-duty applications with power up to 630kW, the VP3000 series delivers robust performance and overload capacity. If you are an OEM looking for a compact, cost-effective drive, the ME300 series is ideal.

Always verify the specific model datasheet for features like built-in EMC filters, communication options, and input phase compatibility. For single-phase input applications, check manufacturer derating recommendations. Our technical team at ISS can help you select the right drive for your application.
