This isolation is necessary to prevent noise from high-current loads (such as actuators) from propagating to sensitive low-power control modules.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCold junction compensation (CJC):\u003c\/strong\u003e The stabilized DC outputs are critical for maintaining the accuracy of CJC circuits on remote analog input cards, as voltage variations can induce drift in high-precision temperature measurements.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the SPU65-302 outputs be connected in series to achieve higher voltage?\u003c\/p\u003e\n\u003cp\u003eA: Series connection of the outputs is not supported without specific factory guidance and appropriate reverse-voltage protection diodes. The unit is designed for independent multi-voltage rail operation as specified in the output configuration table.\u003c\/p\u003e\n\u003cp\u003eQ: Is the unit protected against input voltage surges from the AC grid?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the unit includes integrated surge current protection and over-voltage circuitry. However, in environments with high lightning strike or switching transient risk, external surge protection devices should be installed on the AC input feed.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Secure the power supply within the control cabinet to ensure adequate convection cooling. Maintain at least 50 mm of clearance around the chassis to prevent thermal derating during continuous 80 W operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrounding:\u003c\/strong\u003e Bond the power supply chassis ground to the cabinet's main protective earth bus.
