9905-973 Generator Parts Speed Controller 2301A Speed
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.
9905-973 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 9905-973 device. Multi level password protection can prevent unauthorized changes.

China”s manufacturing industry has achieved world-renowned achievements. From being backward and beaten, to now taking off as a dragon, Chinese manufacturers have put in tremendous efforts and efforts.However, it is undeniable that many products in China are still highly dependent on imports, and there are still technical difficulties that are difficult to overcome in the R&D and production of Chinese products in these fields. Among them are core products related to the lifeline of China”s industry, as well as industrial parts and components that are closely related to our lives. The three technologies that China is stuck in are lithography machines, operating systems, and chips, which are just the tip of the iceberg! This article will take stock of many products that China relies heavily on imports: photolithography machines 0 1The accuracy of the photolithography machine used to manufacture chips determines the upper limit of chip performance, as well as the issue of power consumption. China “s chip technology development is actually very early, but due to various reasons, China”s chip research and development has been delayed. I also shared an article with you earlier, “The chip fraud incident that year caused China’s chip development has been stagnant for more than ten years . ”There are two synchronously moving workpiece stages in the lithography machine, one for carrying negatives and one for carrying films. The two need to be synchronized at all times, with an error of less than 2 nanometers. The two worktables moved from static to dynamic, with an acceleration similar to that of a missile launch. When working, it is equivalent to two large airplanes moving in tandem from takeoff to landing. A knife is stretched out from one airplane to engrave words on the rice grains of the other airplane. The engraving cannot be damaged. Chip 0 2 China”s chip technology, ZTE and Huawei are stuck is a typical example. Although some chips are made in China, many chips still rely on imports. The mass production accuracy of the most advanced foreign chips is 10 nanometers, while in my country it is only 28 nanometers, a gap of two generations. According to reports, in many fields such as computer systems, general electronic systems, communication equipment, memory equipment, and display and video systems, the share of domestic chips in my country is 0.
