USVF-26D | US Electric Single Phase to Three Phase Inverter 5.5 amp 230V

USVF-26D | US Electric Single Phase to Three Phase Inverter 5.5 amp 230V

The USVF-26D is a single-phase to three-phase inverter designed to operate standard 208/230V three-phase AC motors using a 230V single-phase input. It replaces the KB Electronics KBVF-26D and provides a cost-effective solution for powering three-phase machinery such as mills, lathes, and drill presses from single-phase power sources.

Key Specifications

• Voltage: 230V
• Amperage: 5.5 A (maximum output)

Product Features & Fitment

This inverter delivers 100% three-phase power output with over 200% starting torque, ensuring reliable motor startup and operation. It includes a speed potentiometer for adjustable speed control and jumper selections for forward-stop-reverse and enable-automatic-manual modes. The unit supports both 50Hz and 60Hz motors via convenient jumper settings and features sinewave coded PWM for efficient and quiet motor operation at a 16 kHz switching frequency.

For installation, the motor must be wired directly to the inverter terminals, bypassing any existing motor starters to prevent damage. The speed potentiometer must be connected; otherwise, the motor will not run and may be damaged. The inverter is not recommended for use with air compressors or fan-cooled (TEFC) motors running at reduced speeds under full load due to potential overheating. Motor amperage must not exceed the inverter’s rated output. The unit should be powered through an electric power disconnect for safety.
