The Fuji FRN0004G2S-4GU is a 2 hp variable-frequency drive from the FRENIC-Eco series, rated for 3.7 A continuous output on a three-phase 380-480 VAC supply. Input voltage tolerance is +10% / -15%, so it holds regulation through moderate sags common on industrial lines. Output frequency spans 0.1 to 120 Hz, covering standard induction motors and some high-speed spindle applications. Starting torque is 50% at 1 Hz — enough to break away a loaded conveyor or fan without oversizing. Enclosure is NEMA 1 (open type), meaning it is intended for indoor panel mounting where falling dirt and drips are the only contaminants. The heat-sink style (listed as Style: Heat Sink) indicates the power stage relies on external airflow — plan for clearance above and below the drive, and keep ambient below 40 °C for full current rating.
I/O and control
The drive provides 7 digital inputs and 3 analog inputs, plus 5 digital outputs and 2 analog outputs. Control is via keypad or remote contact closure; the keypad shows motor speed with percent, alarm code, menu, and function code on a combined LCD/LED display. Digital readout also cycles through output frequency, current, and voltage. No Ethernet port is included, so communication is limited to the onboard I/O and any optional serial card (not listed here).
Overall dimensions: 10-1/4 in high, 5-7/8 in wide, 6-3/8 in deep. The NEMA 1 enclosure has no gland plate — conduit knockouts or a separate junction box are needed for field wiring. Mounting footprint is standard for this power class; allow 4 inches of free air above and below for convection cooling.
