The TDK-Lambda TCR60S18 is a single-output AC-DC power supply module engineered for industrial and embedded applications requiring stable, regulated DC power. It delivers 18V DC at up to 3.3A with universal AC input compatibility and integral protection against overvoltage and overcurrent faults. The unit employs screw terminal connections for straightforward integration and fan cooling with horizontal air ducting to minimize thermal coupling between adjacent assemblies.
