LS Electric Variable Frequency Drives — Reliable Korean Industrial Automation

LS Electric (formerly LS Industrial Systems, originally a spin-off of LG Industrial Systems) is a South Korean industrial automation manufacturer with over 70 years of history. The company is part of LS Group and is a leading supplier of variable frequency drives (VFDs), PLCs, energy distribution systems, and electric motors in the Asia-Pacific region and Europe. The VFD catalogue on chastotnik.ua features 24 LS Electric models across three series, covering a power range of 0.4–22 kW.

LS Electric Product Series

The LS Electric range in stock covers three main series — iC5, iG5A, and iP5A. Each series is optimised for a specific application type: from compact drives for individual machines to high-performance converters for pumps and compressors requiring precise torque control.

Series Supply Power Key feature Typical application
iC5 1×220 V 0.4–2.2 kW Single-phase supply, built-in EMC filter, IP20 Small machinery, pumps, light commercial
iG5A 1×220 V / 3×380 V 0.4–22 kW Sensorless vector control, wide power range Conveyors, fans, pumps, woodworking equipment
iP5A 3×380 V 5.5–22 kW High torque accuracy, IP20, max frequency 120 Hz Hoists, centrifuges, dynamic-load equipment

How to Choose an LS Electric VFD

Model selection depends on the available power supply, motor rating, and load characteristics. The iC5 series is ideal when connecting directly to a single-phase 220 V supply without a transformer. The iG5A series is the most versatile: it covers 0.4–22 kW and supports both 220 V and 380 V supply options. The iP5A series targets applications requiring high torque control precision on three-phase 380 V supply.

Model Series Power Current (A) Supply Application
SV040IG5A-4 iG5A 4.0 kW 9 A 3×380 V Conveyors, woodworking machines
SV055IG5A-4 iG5A 5.5 kW 12 A 3×380 V Pumps, fans
SV015IG5A-4 iG5A 1.5 kW 4 A 3×380 V Compact industrial equipment
SV008IC5-1F iC5 0.7 kW 5 A 1×220 V Low-power machinery, domestic pumps
SV022IG5A-4 iG5A 2.2 kW 6 A 3×380 V Ventilation, conveyor belts

LS Electric: when we ship the Korean VFD, when INVT GD20 is enough

LS Electric (formerly LG Industrial Systems) is a Korean company since 1974. Our catalogue carries 24 models across 3 series iC5, iG5A, iP5A rated 0.75 to 22 kW. Typical customer for us on LS: machine building, packaging lines, lift OEMs, light OEM production. On price-to-quality LS sits between Korean premium (LS / Hyundai) and Chinese mid-segment (Veichi / INVT): 30-40% above INVT GD20 but with official Korean representation in Ukraine and direct service, which matters for many production-floor customers.

We keep popular iG5A ratings 1.5/2.2/4/5.5/7.5/11 kW in stock. iC5 and iP5A ship by order (5-10 days). 24-month warranty through the LS Ukraine service network. Before the order we ask: encoder on the motor (iP5A required), starts per hour, communication protocols.

LS Electric VFD Series

iC5: Compact Low-Power Series

6 models, 0.75-2.2 kW. Minimum dimensions, easy integration. We ship this for small pumps and fans, plus low-power mechanisms in tight spaces.

iG5A: General-Purpose Industrial Series

12 models, 0.75-22 kW. Sensorless vector control, Modbus RTU. Workhorse for conveyors and pumps, plus general industrial tasks. About 70% of our LS volume runs on this series.

iP5A: High-Performance Series

6 models, 5.5-22 kW. Closed-loop vector control with encoder, industrial protocol support. We ship this where the load needs precise torque control (lifts, winders, tension lines).

Which LS Electric Series to Choose?

Small pump or mechanism up to 2.2 kW: iC5. General industrial task up to 22 kW: iG5A. Application requiring precise torque control: iP5A.
