              Product No.: 212558-141
              Product model: 0
              Updated on: June 19, 2009
              Manufacturer: thermo couple -- Shanghai Feilong instrument & Electrical Co., Ltd




              Product details
              Bwd4k type temperature controller for dry-type transformer is the control device to ensure the safe operation of dry-type transformer. The device adopts the new design, compact structure, intuitive and rich display, and has perfect system self inspection, system protection, parameter setting and saving, various prompt display and working status prompt functions.
              1. Measure and display three-phase working temperature, working environment temperature and working status.
              2. Manual and automatic control of cooling fan, manual test fan function. Automatic control is normal operation control.
              3. The working state of the three-phase fan, the alarm state 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 fan.
              5. Set parameters of the power-off function, strong 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 set arbitrarily.
              7. Automatic calibration function of temperature parameters simplifies complicated manual calibration procedures

               


              1、單片機處理控制系統采用CYGNAL C8051F206做為核心器件,具有強大的數據處理能力,可靠的處理速度和穩定的控制性能。
              2、4*20字符藍色背光液晶顯示界面,美觀典雅,直觀明了,可以同時顯示四相溫度以及系統和風機的工作狀態。液晶顯示器和三個輕觸式快捷鍵提供了友好的人機界面,通過按鍵可以方便的對系統的工作參數進行校準和設置。
              3、電源及信號接口使用菲尼克斯接線端子和功得電子開關保險系統,安全系數有充分絕對的保障。
              4、精致的便于懸掛的儀表外形,充分體現了設計理念,巧妙的懸掛設計方式能夠牢固便捷地將儀表固定在變壓器外殼上,以避免外殼內部的高溫對儀表的影響。
