What it is — FRENIC-MULTI CORE micro drive
The Fuji FRNF12E1S-7U is a FRENIC-MULTI CORE drive, a compact micro drive in the FRENIC-MULTI family. It's a single-phase input unit rated for 230 VAC input and 1/8 HP output, sized for small motor loads like fans, pumps, or conveyors in light industrial or HVAC applications.
The 1/8 HP output at 230 V single-phase input limits the motor load to fractional-horsepower motors. The FRENIC-MULTI CORE series is Fuji's economy micro drive line.
