SCHNEIDER 140CPS11420 POWER SUPPLY MODULE

Schneider 140CPS11420 is a power module for Modicon series programmable logic controllers (PLCS). It provides stable power support for the entire automatic control system and is particularly suitable for applications such as process control, data acquisition, and equipment monitoring in the field of industrial automation.

140CPS11420 is the core power supply module of Schneider Electric's Modicon Quantum series PLC. It is specially designed to meet the centralized power supply requirements of PLC systems, featuring dual output (5.1V DC and 24V DC), supporting two working modes of independent or bus accumulation. It can be adapted to complex power supply scenarios in industrial sites through redundant configuration and parallel expansion.

140CPS11420 Hardware structure:
DC-DC conversion unit: Achieves voltage conversion through power MOSFET and high-frequency transformer, featuring high efficiency and low ripple. It also supports dual independent output control.
Output voltage stabilization and filtering unit: Utilizes synchronous rectification technology and a multi-stage LC filtering circuit to ensure the accuracy and stability of 5.1V and 24V outputs, meeting the power supply requirements for PLC core and peripherals.
Protection and diagnostic unit: Integrates voltage sampling, current sampling, a temperature sensor, and a dedicated protection IC, which can monitor the module's operating status in real time. It responds quickly when the protection mechanism is triggered, and outputs fault signals through LEDs and relays.
Mechanical structure: Standard DIN rail snap-fit design, supporting quick installation and disassembly. The heat dissipation spacing between modules is ≥50mm, ensuring long-term operation.
