Description
9905-969 WOODWARD generator set speed control board
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.
9905-969 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 9905-969 device. Multi level password protection can prevent unauthorized changes.

Microspheres, one-thirtieth the diameter of a hair. In the mobile phone screen, one hundred microspheres are used per square millimeter to hold up two glass panels, which is equivalent to a skeleton. Liquid crystal is poured into the gap between the two glass panels. Without it, the LCD screen you”re staring at wouldn”t be manufactured. Without microspheres, chip production, food safety testing, disease diagnosis, biopharmaceuticals, environmental monitoring… many industries would be in trouble. In the field of microelectronics alone, China imports microspheres worth tens of billions of yuan every year. In 2017, mainland China”s LCD panel shipments accounted for 33% of the world”s total, with an industry scale of approximately US$100 billion, ranking first in the world. However, only one or two Japanese companies in the world can provide the key materials in the panel – spacer microspheres and conductive gold balls. These materials are also like chips, which are stuck in the neck.twenty one”Without three key materials, it is difficult to commercialize fuel cells” (Science and Technology Daily, June 14)Foreign fuel cell vehicles have achieved mass production, but my country”s vehicle fuel cells are still in the technology verification stage. The current situation of vehicle fuel cells in my country is that there are almost no component manufacturers, no vehicle stack production companies, and only a very small number of commercially operating fuel cell vehicles. A number of key materials determine the life and performance of fuel cells. These materials are not completely absent in our country, and some laboratory results have even reached international standards. However, without mass production lines, the fuel cell industry chain is still blocked. Key materials have long been dependent on foreign countries. Once sales are banned, my country”s fuel cell industry will have no basic support.High-end welding power source 22″Domestic welding power source “misfires”, and the robot is powerless in underwater operations” (Science and Technology Daily, June 20)
