ANDU’s Thermal-link & Fusing Resistor(TRXF) is a unique type of Power Resistor, with Over Temperature/ Over Current protections. The Thermal-link(TCO) is placed through the core of wirewound resistor, so TRXF's physical shape looks like ordinary wirewound resistor, but it can effectively solve the hidden safety problem of continuous abnormal heat that ordinary wirewound resistor may cause when small fault current happens.

In normal situation, the current inputs from Pin and Out- puts from Pin 2, flowing through thermal-link (TCO ) and TCO2, and the MOSFET and 8MS are not conducting, therefore no current goes through the R ,R2. When the charging voltage exceeds the OVP rating or 8MS rating, the MOSFET or switch K is activated to conduct. at this moment, the current goes through the R ,R2 and heats it. The heat conducts to TCO and TCO2 rapidly and makes TCOs open the circuit.

In normal situation, the current inputs from Pin and Out- puts from Pin 2, flowing through thermal-link (TCO ) and TCO2, and the MOSFET and 8MS are not conducting, therefore no current goes through the R ,R2. When the charging voltage exceeds the OVP rating or 8MS rating, the MOSFET or switch K is activated to conduct. at this moment, the current goes through the R ,R2 and heats it. The heat conducts to TCO and TCO2 rapidly and makes TCOs open the circuit.

When electric blanket works normally the SCR is opened, and the current flows from the internal thermal-link (TCO) to heat the RL. The LED is turned on. Once the circuit is abnormal, circuit protection detection triggers SCR on, current flows through the R and heats up. The heat trans-
