Manufacturer: SHANGHAI AUTOMATION INSTRUMENT TACHOMETER AND INSTRUMENT MOTOR CO., LTD.
Application: SZJ-4 standard rotation speed generator
SZJ-4 standard rotation speed generating device is a digital and analog by the amount of intelligent control systems for small DC SR. It is the factory SZJ-3 improved products.
As a third-class standard speed device that increases with speed single closed-loop closure to protect the use of microprocessors for control of the size, weight, cost and control accuracy is better than pure analog closed-loop system for control of the double. In addition to speed control of DC chopper-type regulator, relays switch transfer control to increase the amount of the adjustment of the simulation methods to meet specific user needs school table.
This device sub-controller, drive and transmission of three parts, mainly for verification 0.5 below tachometer and speedometer machinery.
Output speed range: 20 ~ 30000r/min
Motor adjustment range: 200 ~ 3000 r / min Resolution 1 r / min
