TWSK Transformer Temperature Controller

TWSK Transformer Temperature Controller

The TWSK Series transformer temperature controller is specifically designed for container transformer stations such as Dry-Type Transformers and Cast Resin Transformers. It can accurately monitor transformer windings, oil, and ambient temperature.

This transformer temperature monitor provides Fans, Alarm, and Trip output relays. Real-time control of the cooling fans, heaters, alarms, and trip actions based on transformer winding temperature sensors and custom programming.

  • 2 Trip Relay
  • 1 over temperature Alarm Relay
  • 1 Power Fan control terminal
  • 1 heater control terminal
  • Two DC 4-20mA analog outputs;
  • Temperature monitoring from -50 ~ 150°C;

Feature

  • Temperature monitoring for transformer: Real-time monitoring of transformer winding or oil temperature. When the oil temperature exceeds the threshold, it automatically triggers over-temperature alarms or trips.
  • Temperature control: Automatically start or stop cooling systems (such as fans) based on set temperature thresholds. When the ambient temperature rises, it starts the fan for cooling.
  • Humidity control: when humidity approaches condensation levels, it activates the heater for dehumidification or dehumidifiers.
  • 3-digit LED display: Real-time monitoring is easy with the 3-digit LED display, providing at-a-glance readings of transformer oil temperature, ambient temperature, and ambient humidity.
  • 3 sensor inputs: Oil temperature sensors, ambient temperature sensors, and ambient humidity sensors are available. The temperature sensor adopts an armored PT100 liquid sensor with a three-wire connection, supporting cable lengths of up to 20 meters. The ambient humidity sensor uses an imported high-reliability integrated sensor.
  • RS485 Communication: Specifically for industrial applications, this transformer temperature controller features an RS-485 Modbus RTU port, ensuring smooth integration with your PLC and other control systems.
