Advanced Power Management Features
The 140CPS11420C delivers both logic power at 5 VDC and field power at 24 VDC simultaneously. Additionally, it includes a built-in cooling fan for reliable operation at maximum load currents. This module automatically selects the correct input voltage range based on user switch settings. You can integrate this power solution with protection devices like the RMS TSG TZ C static trip unit for comprehensive system safety. Furthermore, the Schneider 140CPS11420C provides LED indicators for input power presence and DC output status.
Energy Storage and System Protection
This power supply maintains output voltages during brief AC interruptions using internal storage capacitors. Its 20 ms hold-up time allows the processor to complete critical operations before shutdown. The 140CPS11420C incorporates electronic current limiting to protect both the supply and connected modules. Thermal sensors reduce output power automatically if internal temperatures exceed safe limits. Typical applications include oil and gas, water treatment, chemical processing, and automotive manufacturing systems.
Installation and Configuration Guidelines
Mount the Schneider 140CPS11420C exclusively in the leftmost slot of any Quantum rack for proper backplane connection. Set the voltage selector switch to match your local AC mains voltage before applying power. Ensure adequate ventilation around the module to maintain optimal cooling performance. Finally, verify total system current draw does not exceed 11 A on the 5 VDC output.
