JSD series of products of different specifications and more full-featured. High precision, light weight, stable and reliable quality, flexible installation and easy commissioning and maintenance, can be widely used for automatic control of power plants, metallurgical, chemical, oil, building materials, light industry, as well as water treatment and other industries of the production process. Output: (1) Rotary (2) straight trip (3) multi-turn installation: (1) direct-coupled (2) Base Control: (1) proportional control type (2) Remote Control (3 ) switch-mode (two-position) mainly refers to the proportion of the technical characteristics of the regulated, for remote control type and type the following two items do not involve a abcdef input signal:. 4-20mA b input channel resistance:. 250Ω (or 200Ω) c. Output Current: 4-20mA, output impedance 300Ω d basic error:. 1%, 2.5% e Backlash:. 1.5% f Dead:. 0.5-3% g damping characteristics: no swing h Power supply voltage: Three-phase 380V ~ 50Hz (three-phase four-wire) single-phase 220V ~ 50Hz i work environment: Temperature: -10 ~ 55 ℃ whole discrete -25 ~ 70 ℃ Humidity: ≤85% ambient air does not contain corrosive gas j. Protection class: meet the IEC145 IP65 JSD series of products mainly consists of motor, reducer, torque switches, limit switches, control box, manual - electric mechanical limit switch and position transmitter and other components. 1. Using worm, planetary, helical and other transmission mode, so the transmission mechanism has a variety of gear ratios to choose from, after the effective combination, expand the product's specifications. 2. The motor has a thermal protection. 3. With over torque protection. 4. With electrical limit function. 5. provide a remote 4-20mA feedback signal for the user. 6. With reliable electrical braking function (patented technology). 7. with phase protection. 8. With automatic calibration phase. 9. The base made of aluminum castings so light weight, installation common good.
