BWD3KSD type dry-type transformer computer temperature controllerDetailed product description：

Function of BWD3KSD dry-type transformer computer temperature controller

1. Detect and display the temperature of the three-phase winding of the transformer or only display the temperature of the highest phase winding of the transformer. During the tour display, each phase is displayed for about 6 seconds, and the fastest can reach 1 second.
2. Fault sound and light alarm: When the sensor fails, the corresponding A, B, and C phase indicator lights will turn on, and the fan will start. The temperature controller will make a "beep beep" sound and connect the alarm contact. The LED displays' X-HO 'or' X-LO ', with' X 'indicating the faulty phase.
3. Fan start and stop function: When the temperature of one phase winding in the three-phase winding of the transformer reaches the set fan start temperature value, the fan will start automatically, and the fan indicator light will light up when the fan starts. When the temperature of the three-phase winding of the transformer is lower than the set fan shutdown temperature value, the fan will automatically shut down.
4. Overtemperature alarm function: When one of the three-phase windings of the transformer reaches the set overtemperature alarm temperature, the temperature controller emits sound and light alarms, and connects the alarm output terminal to provide a set of switch signals to the remote control cabinet.
5. Overtemperature tripping function: When one of the three windings of the transformer reaches the set tripping temperature value, the temperature controller connects the tripping output terminal and provides a set of switch signals to the remote control cabinet to start the tripping circuit. To prevent tripping due to accidental factors, a delay of approximately 5 seconds is provided.
6. Manual start/stop fan function: Press the fan button to start the fan, then press the fan button again to turn off the fan. The manual fan will automatically shut down after about 15 minutes of starting.
7. Fan timing detection function: In order to avoid corrosion, blockage, and damage caused by the fan not starting for a long time, a fan timing detection function is specially designed. The timing start time can be freely set within the range of 0-199 hours. When the set value is reached, the fan starts once, with a start time of about 2 minutes. When entering '000', the function will be cancelled.
8. Control function self-test: It can simulate the input temperature value to make the temperature controller perform corresponding functions. At this time, the "black box" function does not work.
9. Black box function: It can record the temperature of the three windings of the transformer when the thermostat is powered off, as well as the working status of the machine.
10. The temperature settings can be directly adjusted through the touch keys on the panel. To prevent unauthorized personnel from changing settings, the thermostat is equipped with a password that can only be set if entered correctly. Otherwise, it can only be viewed and cannot be set, and the thermostat emits an alarm sound of 'beep'.
