Product Description

The TWSK Series transformer temperature controller is specifically designed for the container transformer stations. It accurately measures the oil temperature of the transformer and the environment temperature. Real-time control of the cooling fans, heaters, alarms, and trip actions based on transformer winding temperature sensors and custom programming. when the oil temperature exceeds the threshold, it automatically triggers over-temperature alarms or trips, when the ambient temperature rises, it starts the fan for cooling, and when humidity approaches condensation levels, it activates the heater for dehumidification.

The temperature sensor adopts an armored PT100 liquid sensor with a three-wire connection, supporting cable lengths of up to 20 meters. It provides precise temperature readings without the need for compensation or calibration. The controller is also equipped with RS485 communication for remote monitoring and data transmission

Feature

• 3-digit LED display;
• Automatic fan/heater control;
• Over temperature alarm;
• PT100 temperature sensor input;
• Two DC 4-20mA analog outputs;
• Temperature monitoring from -50 ~ 150°C;
• RS485 with Modbus RTU protocol.
