BWDK-S201D Dry type transformer temperature monitor controller-INNO

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:

Especificaciones técnicas

Environmental humidity:<95% (25 ℃).
voltaje de trabajo: CA 220 V (+10%, -15%).
Frecuencia de trabajo: 50Hz o 60 Hz (±2Hz).
Rango de medición: -30.0 ℃ a 240.0 ℃.
Precisión de medición: ± 1% FS (nivel del controlador de temperatura 0.5, nivel del sensor B).
Resolución: 0.1 ℃.
Fan output capacity: 9Aire acondicionado/250 VCA.
Controlar la capacidad de salida: 5Aire acondicionado/250 VCA; 5A/30 VCC (resistador).
Temperature controller power consumption: ≤ 8W.
Características
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.
control del ventilador: 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.
Función de alarma: 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 “caja negra” función, 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, bloqueo, and damage caused by long-term failure to start the fan; Función de prueba de simulación, convenient for users to debug and test; Función de compensación digital, which can calibrate temperature measurement; The cabinet door opening alarm function can prevent unauthorized personnel from operating.
