0.75kW Invertek Optidrive E3 IP66 Switched 1 Phase 200-240V 4.3A with EMC Filter VFD (no brake transistor)

The Invertek single-phase switched inverter—specifically, models like the Optidrive E3—delivers precise and reliable speed control for permanent split capacitor (PSC) and shaded-pole single-phase induction motors. Designed for robust industrial or commercial use, this inverter is ideal for fans, blowers, pumps, and similar low starting torque applications where three-phase power is unavailable or cost-prohibitive.​

Key Features

• 200–240V output
• Switched IP20 or IP66 enclosure options (suitable for outdoor or harsh environments)
• Factory-installed EMC filter for electrical compliance
• Fast, intuitive setup with 14 basic parameters and default macros for industrial, fan, or pump operation
• On-board keypad and potentiometer for easy local operation; OFF/REV/FWD switching enables rapid commissioning and local control​
• Built-in PI controller and Bluetooth connectivity on select models​
• Motor current, RPM indication, and status LEDs

Typical Applications

• Centrifugal pumps
• Industrial fans and ventilators
• Air flow controllers
• Blowers and fume extractors

Core Technical Specifications

• Input voltage: 200–240V AC
• Output voltage: 0–supply voltage; frequency adjustable via digital control
• IP66 (outdoor use, fully switched)​

Benefits

• Cost-saving single-phase solution for locations without three-phase supply
• Rugged, compact design for space-limited installations
• Pre-configured for most common industrial uses out-of-the-box; advanced flexibility via application macros
• UK-manufactured and certified to ISO 9001 and ISO 14001 standards​

This inverter is well-suited as an energy-efficient, easy-to-integrate speed control drive for single-phase motor-driven systems in commercial and light-industrial environments.
