Designed for Outdoor & Harsh Environments

Unlike standard IP20 drives, this Optidrive E3 is suitable for outdoor mounting (subject to the required installation criteria being followed - see downloads), with a rugged enclosure that is:

• Dust-tight

• Resistant to water jets and washdown

• Suitable for agricultural and industrial environments

The sealed design allows installation without additional panels or enclosures, reducing installation cost and complexity.

Applications

• Conveyor systems

• Pumps & fans

• HVAC systems

• Small machinery & automation

• Compressors

This inverter is particularly suited for applications requiring reliable speed control and energy efficiency without complex setup.

What’s the Difference: 3F4A vs 3F4B?

• ODE-3-440390-3F4A
  → Non-switched (no built-in controls other than the keypad and control terminals)
  → Ideal for use when connected to control panels, remote buttons or automation systems

• ODE-3-440390-3F4B (This model)
  → Includes input mains isolator, speed potentiometer & forward/stop/reverse switch

Why Choose the Optidrive E3?

• Fast installation – ready to run with minimal setup

• IP66 outdoor rated plastics – suitable for plant room or external mounting

• Flexible motor compatibility – supports multiple motor types

• Cost-effective solution for industrial motor control

The Optidrive E3 series is widely trusted for its simplicity, durability, and performance in demanding environments.
