Working principle

The core working principle of YOKOGAWA F3PU10-0N AC power module is to convert the unstable AC input voltage in the industrial field into a stable DC voltage required by the PLC system through high-frequency switching power technology, achieving efficient conversion and reliable supply of electrical energy. After the module is connected to an AC power supply of 100-240V, it first passes through a front-end EMI (electromagnetic interference) filtering circuit, which can effectively suppress clutter interference in the power grid and block interference signals generated inside the module from feedback to the power grid, ensuring bidirectional electromagnetic compatibility between the power grid and the module.

The filtered AC voltage enters the rectifier bridge circuit and is converted into pulsating DC voltage; Subsequently, through the power factor correction (PFC) circuit, the input power factor was increased to nearly 1, which not only improved the efficiency of energy utilization but also reduced harmonic pollution to the power grid, meeting the industrial grade power quality standards. The pulsating DC voltage enters the high-frequency switch circuit again, and the conduction and turn off of the switch tube are controlled by PWM (Pulse Width Modulation) technology. With the cooperation of high-frequency transformers, voltage level conversion and electrical isolation are achieved, converting high-voltage pulsating DC into low-voltage pulsating DC.

Finally, the low voltage pulsating DC is smoothed by an output filtering circuit (composed of capacitors and inductors) to output a stable DC 24V DC voltage to the backend load. At the same time, the built-in voltage and current detection circuits and temperature sensors in the module monitor the output status and the module's own temperature in real time. When abnormalities such as overvoltage, overcurrent, overheating, or short circuit are detected, the corresponding protection mechanism is immediately triggered: when overvoltage/overcurrent/overheating occurs, the output is limited or cut off by adjusting the PWM signal, and the fault is automatically restored after troubleshooting; When there is a short circuit, it enters the locking mode and needs to be powered off to eliminate the fault before restarting the module to restore power supply. In addition, the module achieves wide input voltage adaptation through an internal voltage regulation circuit, ensuring that the output voltage remains stable within a fluctuation range of ± 10% of the input voltage.
