Product Description:
The RD51.1-4B-004-P-NN-FW Frequency controller is the product of Bosch Indramat company. It is part of the RD 500 RD51 series to provide scalar control based on voltage and frequency characteristics. It has an IP20 designation so that it may be used indoors, inside cabinets, or other enclosed areas.
The RD51.1-4B-004-P-NN-FW frequency controller generates standard output power of 4 kW. Its three-phase AC input voltage range of operation is 380-480 volts with a tolerance of 0-10%. Its input frequency is the range of 50/60 Hz ~5%. The controller offers an output frequency between 0 and 500 Hz. The switching frequency can go up to 12 kHz. It complies with the EN 50178. It shows the established safety standards to be observed in power systems with regard to electronic equipment. The RD51.1-4B-004-P-NN-FW frequency controller has a built-in brake chopper and is not supplied with software. Firmware has to be installed externally. The unit has forced air cooling. It is fitted with a rear heatsink that runs through the panel cutout. This will provide thermal isolation control and airflow. It conforms to the EMC requirements based on EN 61800-3. The width of the controller is around 150 mm, 380 mm, and 220 mm deep. This controller weighs around 7.3 kg.
The RD51.1-4B-004-P-NN-FW frequency controller is able to withstand an overload up to 150% of the rated current. It is without interruption to a maximum of 60 seconds. It can offer a short-term surge of 200 percent of the rated current, top a maximum of 0.5 seconds. It is designed to operate up to 1000 meters above sea level without derating, though it needs derating at higher altitudes. The frequency converter is most suitable where a given motor speed control is desired. It is also a reliable source of voltage and frequency control in an industrial automation environment.
