Schneider 140CPS52400

I. Overview

Schneider 140CPS52400 is a high-reliability redundant power supply module. It serves as the core power supply unit for industrial automation systems, specifically designed for critical industrial control applications that demand extremely high power supply stability and continuity. It is an essential component ensuring the continuous and stable operation of PLC systems including CPU, I/O modules, communication modules and other units.

Its core function is to convert 100~150VDC input voltage into a stable 5.1VDC output voltage, providing reliable power supply for the entire Modicon Quantum rack and all installed modules. It integrates redundant operation, overload protection, overvoltage protection and other features, effectively handling single-point power failure and preventing system shutdown caused by power interruption.

The module supports two operating modes: Redundant Mode and Standalone Mode. It can be used individually, or two modules can be paralleled for full redundant power supply. If one module fails, the other can seamlessly take over power output to maintain uninterrupted system operation.

The module delivers an output current of 8A to meet the power demand of multiple modules working simultaneously. The input current is 500mA at 125VDC, with an inrush current of 28A at 125VDC. It can withstand an input power interruption up to 1ms to cope with instantaneous power fluctuation.

Adopting industrial reinforced design, it operates within 0℃~60℃ and features excellent anti-static and anti-electromagnetic interference performance. Compatible with standard Modicon Quantum racks, it is widely applied in critical industrial fields such as power, chemical and metallurgy, delivering highly reliable and stable power guarantee for automation systems.

III. Technical Features

Flexible Redundant Power Supply Design
Supports Redundant and Standalone operating modes. It can be deployed alone or configured in parallel with two identical modules to build a full redundant architecture. When one module fails, the other takes over power supply seamlessly without interruption, greatly improving power supply reliability in critical industrial scenarios and avoiding production downtime and losses caused by power faults.
Stable Voltage Conversion Performance
It precisely converts wide-range 100~150VDC input into stable 5.1VDC output with 8A output current, fully meeting the combined power consumption of Modicon Quantum rack, CPU, I/O and communication modules. High voltage output accuracy effectively eliminates the impact of voltage fluctuation on module operation.
Comprehensive Protection Mechanism
Built-in output overvoltage and overload protection automatically monitors output voltage and current. In case of overvoltage or load overload, the module cuts off power or limits current timely to protect itself and connected PLC equipment from damage and extend service life.
Strong Anti-interference & Anti-fluctuation Capability
Excellent anti-static performance (Contact: 4kV; Air: 8kV, compliant with IEC 801-2) and electromagnetic interference resistance (80~2000MHz, 9.14V/m, compliant with IEC 801-3), adapting to complex electromagnetic industrial environments. Withstanding up to 1ms input power interruption ensures stable operation against instantaneous power surges and drops.
Intuitive Status Monitoring
Equipped with one green PWR OK LED to clearly indicate power status. The LED lights up under normal operation and turns off upon fault, enabling on-site maintenance personnel to quickly judge module status and troubleshoot power supply faults.
Industrial-grade High Reliability
Designed with high-quality industrial electronic components, operating stably under harsh conditions including wide temperature range 0℃~60℃, high humidity up to 95% non-condensing, and altitude up to 5000m. Low failure rate meets the demand of long-term continuous operation for critical industrial systems.
Seamless System Compatibility
Specially designed for the Modicon Quantum automation platform, it can be directly installed on the standard rack and perfectly compatible with all modules on the platform without additional modification. Easy deployment meets power supply requirements of complex industrial control architectures.
