ENEXT e.f-drive Frequency Converters — Ukrainian Brand for Industrial Automation

ENEXT is a Ukrainian electrical equipment company founded in 2000, with its own service centre and technical support in Ukraine. The e.f-drive lineup comprises frequency converters (VFDs) of the company's own design, combining an affordable price point with compliance with industrial standards and local after-sales support.

Chastotnik.ua stocks 30 ENEXT e.f-drive models across two series: the budget-friendly e.f-drive.stand and the performance-oriented e.f-drive.pro. All models are available and ready for delivery across Ukraine.

e.f-drive.stand Series — Affordable Solution for Pumps and Fans

The e.f-drive.stand series is designed for constant-torque applications: pumps, fans, conveyors, and basic machine tool drives. It offers the lowest entry price in the ENEXT lineup and supports single-phase 220 V input — making it practical for small workshops and facilities without a three-phase supply.

  • Power range: 0.4 to 5.5 kW
  • Single-phase input 1×220 V: models 0.4, 0.75, 2.2 kW
  • Three-phase input 3×380 V: models 0.75–5.5 kW
  • Output frequency up to 400 Hz
  • Enclosure rating IP20
  • Built-in EMC filter

e.f-drive.pro Series — SVC Vector Control for Demanding Applications

The e.f-drive.pro series employs sensorless vector control (SVC) and is rated for variable and impact loads: compressors, pumping stations, hoisting equipment, and machining centres. The power range of 0.75 to 220 kW covers the vast majority of industrial motor sizes.

  • Power range: 0.75 to 220 kW
  • Input: three-phase 3×380 V
  • Output frequency up to 300 Hz
  • Control: sensorless SVC vector
  • Enclosure rating IP20
  • Built-in EMC filter

Frequently Asked Questions

A VFD is an electronic device that converts AC mains voltage to DC (rectifier stage), then back to AC with adjustable frequency and amplitude (inverter stage). By varying the output frequency from 0 to 600 Hz, it smoothly controls the rotational speed of an AC induction motor from standstill to rated speed and beyond, while limiting starting current to 1.5× rated.
