Description
5461-770 WOODWARD 2301A Speed Control Controller
Non differential regulation is mainly used for constant speed control and is suitable for single machine operation or multiple prime movers working together in an isolated power grid. Differential regulation provides more control flexibility.
further enhancing its performance and application range.
rich additional functions, and high-precision output signals. Whether it is in the fields of generator sets, compressors, pump stations, or ships and locomotives, it can effectively ensure the stable operation of equipment within the set range.
power measurement level 1, editable screen, multi interface toolkit connection, etc. All details can be found in Woodward easyYgen manual 37582A
The rated operating temperature range of this model is -20 to 70 ° C; the rated temperature range of the LT model is -40 to 70 ° C, suitable for outdoor use.
5461-770 is equipped with a monitor (not available on the 3100 model) and is designed for front panel installation.
The built-in HMI has a color LCD and soft keys (now with dedicated buttons) for direct control of the 5461-770 device. Multi level password protection can prevent unauthorized changes.
The generator set has four operating modes and the option to configure a manual circuit breaker control device.

[Introduction] PLC and frequency converter are two important electrical equipment in the field of industrial automation control. This book combines the introductory knowledge of PLC and frequency converter. The main contents include introduction to PLC, PLC composition and principle, and the use and application of PLC programming software. System development, basic instructions and applications, step instructions and applications, functional instructions and use, the structure and principle of the frequency converter, the use of the frequency converter, as well as the selection, installation and maintenance of the frequency converter.What is a frequency converter ? Generally speaking, it is: AC – DC – AC (it can also be said to be rectifier first – then inverter). The frequency converter that undergoes this process is also called AC-DC-AC frequency conversion. Currently, it is also used in various industries. One of the more commonly used ones. In addition, there is also an AC-AC conversion, which is also called an AC converter.1. What is a frequency converter?Frequency converter is a power control device that uses the on-off function of power semiconductor devices to convert industrial frequency power into another frequency. The frequency converter is mainly composed of rectifier (AC to DC), filtering, inverter (DC to AC), braking unit, drive unit, detection unit, microprocessing unit, etc.The frequency converter is a device that converts industrial frequency power supply (50Hz or 60Hz) into AC power supply of various frequencies to realize variable speed operation of the motor. The control circuit completes the control of the main circuit, and the rectifier circuit converts the AC power into DC power. The DC intermediate The circuit smoothes and filters the output of the rectifier circuit, and the inverter circuit reverses the DC power into AC power. For inverters that require a lot of calculations, such as vector control inverters, sometimes a CPU for torque calculation and some corresponding circuits are needed. Variable frequency speed regulation achieves the purpose of speed regulation by changing the frequency of power supply to the motor stator winding.
