The LS Electric SV022IG5A-4 belongs to the Starvert iG5A series of compact AC drives designed for economical yet capable control of three‑phase induction motors in HVAC, water treatment, and general machinery. It accepts a 3×380–480VAC, 50/60Hz supply and drives motors up to 2.2kW (3HP) with 6A rated output current, offering both V/f and sensorless vector control for high starting torque (up to 150%) and stable low‑speed operation. The inverter supports a wide 0.1–400Hz output frequency range, acceleration/deceleration times from 0.1 to 6000s, and 150% overload for 60 seconds, making it suitable for both heavy and light duty cycles.
An integrated keypad and 7‑segment display simplify local setup, while analog (0–10V, 0/4–20mA) and multiple digital inputs allow flexible speed and start/stop control from PLCs or potentiometers. The drive includes built‑in braking chopper (external resistor required), EMC filter, RS485 (Modbus RTU/LS Bus) communication, PID control, and comprehensive protections (over‑current, over‑power, over/undervoltage, short‑circuit, over‑temperature, brown‑out), all in a compact IP20 enclosure sized 140×128×155mm and weighing about 1.84kg.
