The Fuji Electric FRN250G1S-4U is a Frenic-series variable frequency drive rated for 200 HP at 480 VAC three-phase, delivering 253 A continuous output. It includes a built-in brake transistor for dynamic braking on high-inertia or vertical loads, and the IP20 enclosure suits panel-mount installations where the drive is protected from the environment but not washdown.
Sizing and duty
Rated 253 A and 200 HP on 480 VAC. The built-in brake transistor handles dynamic braking without an external unit.
Installation notes
Panel-mount the drive with adequate clearance above and below for airflow — the IP20 enclosure relies on natural convection or forced ventilation depending on ambient temperature. The built-in brake transistor requires an external braking resistor wired between the DC bus and brake terminals; resistor sizing depends on the duty cycle and inertia. Input power is 480 VAC three-phase; verify that the supply side has proper overcurrent protection per local code.
