BWDK-S201D is a flip-top embedded small molded case dry-type transformer intelligent temperature controller independently developed and produced by Fuzhou InnoTech, which is mainly used for temperature control and monitoring of dry-type transformers. The following is its detailed introduction:
- Technical Parameter
- environmental temperature: -20℃~+55℃.
- Environmental humidity: <95% (25°C).
- operating voltage: AC 220V (+10%, -15%).
- operating frequency: 50Hz or 60Hz (±2Hz).
- Measurement range: -30.0°C to 240.0°C.
- Measurement accuracy: ±1% FS (thermostat class 0.5, sensor class B).
- resolution (of a photo): 0.1°C.
- Fan Output Capacity: 9A/250VAC.
- Control output capacity: 5A/250VAC; 5A/30VDC (resistive).
- Thermostat power consumption: ≤8W.
- Functional Features
- Temperature display: With three-phase circuit display and maximum value display function, you can know the temperature of the transformer three-phase winding in real time.
- Fan controlSupport fan auto/manual start/stop function, which can automatically control the operation of the fan according to the set temperature threshold, or manually turn on the fan forcibly.
- Alarm function: With over-temperature alarm, fault alarm function, when the temperature of one phase of the three-phase line package temperature over-temperature or sensor failure and so on, the thermostat will send out sound and light alarms and output the corresponding switching signals.
- Trip function: When the temperature reaches the set over-temperature trip value, the thermostat will output a trip signal to cut off the power supply of the transformer to protect the transformer.
- Other Functions: It also has the "black box" function, which can record the temperature of three winding wire packages and the working status of the machine before the power failure; the fan timing excitation function, which can avoid the fan not starting for a long period of time and rusting and blocking damage; the simulation test function, which is convenient for users to carry out debugging and testing; the digital compensation function, which can be calibrated to the temperature measurement; cabinet door opening Alarm function can prevent unauthorized personnel from operating.
