Number of products: 212558-141
Product model: 0
Manufacturer: Thermocouple--Shanghai Feilong Instrument Electric Co., Ltd.
BWD4K dry-type transformer temperature controller is a control device to ensure the safe operation of dry-type transformers. The device adopts a new design, compact structure, intuitive and rich display, and has perfect system self-test, system protection, parameter setting and storage, and various prompt displays and working status prompt functions.
1. The measurement shows the three-phase working temperature and working environment temperature, and the working status is displayed.
2. Manual and automatic control of the cooling fan, manual is for testing the fan function. Automatic control is normal operation control.
3. The working status of the three-phase fan of the system, the alarm status of the system, the three-phase working temperature and the ambient temperature are displayed at the same time.
4. Independent control output of three-phase fan, compatible use of three-phase and single-phase fan.
5. Power-down holding function for setting parameters, powerful network function.
6, high temperature and ultra high temperature alarm output and alarm display, high temperature and ultra high temperature alarm temperature and fan start and stop temperature can be arbitrarily set.
7. Automatic calibration of temperature parameters, simplifying complicated manual calibration procedures
1. The single-chip processor control system uses CYGNAL C8051F206 as the core device, which has powerful data processing capabilities, reliable processing speed and stable control performance.
2, 4 * 20 character blue backlit LCD display interface, beautiful and elegant, intuitive and clear, can display four-phase temperature and system and fan working status at the same time. The LCD display and three touch-sensitive shortcut keys provide a friendly human-machine interface, and the system's working parameters can be easily calibrated and set through the keys.
3. The power supply and signal interface use Phoenix Contact terminals and Gongde electronic switch insurance system. The safety factor is fully and absolutely guaranteed.
4. The exquisite and easy-to-suspend instrument appearance fully reflects the design concept. The clever suspension design method can firmly and conveniently fix the instrument to the transformer casing to avoid the high temperature inside the casing from affecting the instrument.
