Schneider 140CPS12400R is a redundant power supply module in Schneider Electric’s Modicon Quantum series,designed for industrial automation systems,providing high reliability and flexible power supply solutions.The following is a comprehensive analysis of its core functions and technical features:
I.Core functions and technical features
Redundant power supply design
The dual power supply redundancy mode is adopted to ensure that the system can still operate stably when a single power supply fails.It is suitable for industrial scenarios with extremely high continuity requirements(such as electricity,chemical industry,and rail transportation).
Wide voltage input and output
Input voltage:supports 115V/230V AC(50/60Hz),with a wide input voltage range(93-276V AC),which can adapt to different power grid environments.
Output voltage:Provides 5V DC bus voltage to support Modicon Quantum series CPU,interface module and I/O module power supply.
Multiple power supply modes
Independent mode:Suitable for 3A or 8A low-load configuration,without redundancy.
Independent superimposable mode:Expand the power supply capacity by connecting multiple modules in parallel,suitable for high load requirements.
Independent redundant mode:dual module hot backup to achieve uninterrupted power supply.
Protection and safety features
Overcurrent/overvoltage protection:built-in overcurrent,overvoltage and short-circuit protection circuits to prevent equipment damage.
Surge suppression:the maximum input surge current is 38A(115V)or 19A(230V),which improves anti-interference ability.
2.Technical parameters
Rated output current:maximum 5.1A in independent mode,maximum 8A in redundant mode(at 60°C).
Power factor:0.5,efficiency optimized to meet the needs of industrial environments.
Protection level:not clearly marked,but meets industrial protection standards(such as IP20).
Operating temperature:-20°C to 60°C(storage temperature-40°C to 70°C).
