BWDK-S201D is an intelligent temperature controller for flip type embedded small plastic shell dry-type transformers independently developed and produced by Fuzhou INNO. It is mainly used for temperature control and monitoring of dry-type transformers. Here is a detailed introduction:
Technical Specifications
Environmental temperature: -20 ℃~+55 ℃.
Environmental humidity:<95% (25 ℃).
Working voltage: AC 220V (+10%, -15%).
Working frequency: 50Hz or 60Hz (± 2Hz).
Measurement range: -30.0 ℃ to 240.0 ℃.
Measurement accuracy: ± 1% FS (temperature controller level 0.5, sensor level B).
Resolution: 0.1 ℃.
Fan output capacity: 9A/250VAC.
Control output capacity: 5A/250VAC; 5A/30VDC (resistive).
Temperature controller power consumption: ≤ 8W.
Features
Temperature display: It has three-phase circuit display and maximum value display functions, which can real-time understand the temperature situation of the three-phase winding of the transformer.
Fan control: Supports automatic/manual start stop function of the fan, which can automatically control the operation of the fan according to the set temperature threshold, or manually force the fan to start.
Alarm function: It has over temperature alarm and fault alarm functions. When one phase of the three-phase wire package exceeds the temperature or there is a sensor failure, the temperature controller will emit sound and light alarms and output corresponding switch signals.
Trip function: When the temperature reaches the set over temperature trip value, the temperature controller will output a trip signal to cut off the power supply of the transformer to protect it.
Other functions: It also has a “black box” function, which can record the temperature of the three winding wire packages before the power outage and the working status of the machine; The timed excitation function of the fan can avoid corrosion, blockage, and damage caused by long-term failure to start the fan; Simulation testing function, convenient for users to debug and test; Digital compensation function, which can calibrate temperature measurement; The cabinet door opening alarm function can prevent unauthorized personnel from operating.
