Bộ điều khiển nhiệt độ điện tử BWD-3K BWD-3KR electronic temperature controller

The function description of the dry-type transformer electronic instrument produced by our company is as follows :

1.  The instrument can measure the temperature of the three-phase windings of dry-type transformers, and display the three-phase temperature values ​​simultaneously in numbers.

2.  The instrument can use keys to input 4 temperature setting values. When the measured temperature exceeds each set value, the start and stop of the fan, over-temperature alarm, and ultra-high temperature trip are respectively controlled. The temperature setting value can be modified at any time and will not disappear after power off.

3.  The instrument has the function of sensor disconnection fault detection.

4.  The instrument has the function of automatic timing start of the fan.

5. The instrument has the function of recording the historical maximum value of temperature.

6. According to the needs of use, the instrument can provide digital or analog remote transmission.

Technical Parameters:

Temperature measurement range: 0  ~  200 ℃ .

Temperature measurement accuracy: Class 1.0

Display mode: Three sets of digital tubes simultaneously display the temperature of A , B , and C phases, with a resolution of 0.1 °C. 

Optional: three 4-20mA analog output or RS485 serial communication output (using MODBUS protocol) .
