The Fuji Electric FRN0035G2S-4GU is an active-production FRENIC-MEGA drive rated for 20 hp at 30.5 A output, with a 380 to 480 VAC three-phase input. It's a compact, open-frame unit with a built-in heat sink, so it's ready for panel mounting without extra cooling ductwork.
What the ratings mean for fit
The 30.5 A maximum output current is the hard limit for continuous motor load — size your motor nameplate at or below that to avoid nuisance tripping on overload. The 200% starting torque at 1 Hz (/) means it'll break loose a stuck pump or conveyor without needing a bigger frame; that's a real advantage on high-inertia starts. Input accepts 380 to 480 VAC, 50/60 Hz, so it lands on most common global line voltages without a transformer tap. Output frequency range of 25 to 500 Hz covers standard induction motors and higher-speed spindles, though the 500 Hz top end is really for specialized applications — most general-purpose work lives under 120 Hz. The built-in Ethernet port means you can plug it directly into a plant network for Modbus TCP or similar protocol without an add-on card. I/O count is generous: (9) digital inputs, (6) digital outputs, plus (3) analog inputs and (2) analog outputs — enough for a basic speed/start-stop setup with feedback.
Where it's used
This drive is built for precise motor control in constant-torque or variable-torque applications — think conveyors, fans, pumps, and small machine tools. The NEMA 1 enclosure is fine for indoor dry locations; if it's going into a washdown area, you'll want it inside a separate IP-rated cabinet.
