About the 200FN4031
200FN4031 is a motor controller from the FlexPak 3000 series, distributed by Reliance Electric. The controller is designed to convert 460 VAC inputs into the appropriate DC output. The maximum horsepower that this driver can supply is 200 HP. The typical power efficiency when this driver is combined with a motor is 89%. The armature and field voltage rating for this controller is 500 VDC and 300 VDC respectively. Speed control for the controller is based on the DC tachometer input.
The controller has a variety of parts which may be required to operate effectively. These parts include theA-C line fuse, the field fuse, the A-C line disconnect, the inverting fault breaker, and the armature fuse. Voltage and current ratings for these components should be carefully selected by the end user to ensure proper and safe operation. A-C line fuses are recommended to be rated for 500 volts, while armature and field fuses are recommended to be 700 V and 600 V respectively. The disconnects are recommended to be rated for 600 V.
It is important for the user to ensure that all appropriate wiring practices are followed when installing and operating the driver, in order to maintain safe operation. Reference signals should use double or triple twisted conductor wires, AWG No. 16, with a rating of 600 V. These signal wires should be kept separate from high voltage and noise conductors. Tachometer feedback and similar signalling should be operated using isolated conduits. Wire length between the motor and the controller should not exceed 1000 feet.
