LS Electric LSLV0040S100-2EONNS Inverter VFD Low Voltage Drive

Description

LS Electric LSLV0040S100-2EONNS Inverter VFD (S100 — Standard Drive)

Three-phase input / three-phase output standard drive (S100 series) by LS Electric, offering general-purpose control with dual torque ratings and typical features for mid-power motor drives.

The Polar Energy Assessment:

The LSLV0040S100-2EONNS sits in the mid-power range. It handles a 4.0 kW (HD) to 5.5 kW (ND) class motor, supports V/f, sensorless vector, and built-in communications. It’s solid for industrial automation, HVAC, pumps, fans — but be sure to house it in a cabinet when there’s dust, humidity, or mechanical strain, because of its IP20 rating.

Pros

• Dual torque ratings (Heavy Duty & Normal Duty) for load flexibility.
• Supports common control methods: V/f, slip compensation, sensorless vector, and PM sensorless.

• Built-in Modbus RTU (LS INV 485) plus optional fieldbus (Profinet, EtherNet/IP, CANopen, Profibus-DP).
• Overload capacity: 150 % for 1 min (HD), 120 % for 1 min (ND).
• Compact form factor (Frame C) suitable for panel installation.
• Standard compliance: KC, CE, UL, cUL.

Limitations

• No built-in EMC filter on the “2EONNS” variant.
• Enclosure protection: IP20 — vulnerable to dust, moisture, and outdoor conditions.
• At high altitudes or extreme temperature, derating required (spec says derate 1 % per 100 m above 1,000 m).

Typical use cases

• Industrial pumps, fans, blowers in manufacturing plants.
• HVAC systems in large buildings.
• Conveyor drives, machine tools in mid-power ranges.
• OEM systems that require moderate power and reliable drive control functions.
