Working principle
As the core power supply component of industrial automation systems, the YASKAWA JRMSP-P8101 power supply operates based on PWM pulse width modulation for AC-DC power conversion and precise voltage regulation control logic. The power supply mainly consists of an input filtering circuit, a rectification circuit, a power conversion circuit, a control circuit, an output filtering circuit, and a protection circuit. Firstly, the AC power of the industrial power grid enters the power supply through the input interface, and is filtered out of harmonics and interference signals in the power grid through the input filtering circuit. Then, the AC power is converted into pulsating DC power through the rectification circuit; Next, the power conversion circuit, driven by the control circuit, converts pulsating DC power into high-frequency pulsating AC power through PWM pulse width modulation technology, and then converts it into low-voltage pulsating DC power after isolation and voltage reduction by a high-frequency transformer; Subsequently, the output filtering circuit smooths and filters the low-voltage pulsating DC power, outputting stable and pure DC 24V DC power to supply power to the backend load equipment; At the same time, the control circuit samples the output voltage and current signals in real time, compares them with the reference voltage, and dynamically adjusts the PWM pulse width to ensure stable output voltage; In addition, the protection circuit continuously monitors the operating status of the power supply. Once abnormalities such as overvoltage, overcurrent, short circuit, and overheating are detected, the protection mechanism is immediately triggered to cut off the output or limit the output current, ensuring the safety of the power supply and backend load devices.
Precautions
-Voltage matching and input protection: Before installation, it is necessary to confirm that the input voltage range is consistent with the industrial grid voltage. It is strictly prohibited to apply voltage beyond the rated range to prevent power supply burnout; It is recommended to install surge protectors and input filters at the power input end to further suppress power grid surges and electromagnetic interference, and improve power supply stability; When not in use for a long time, the input power should be disconnected to avoid component aging caused by standby current and extend the service life.
-Safety operation regulations: When wiring, repairing or replacing components, the power must be disconnected first, and touching the terminals while powered on is strictly prohibited to prevent electric shock accidents.
-Correct wiring and load matching: strictly follow the wiring manual to distinguish between input terminals, output terminals, and grounding terminals. It is strictly prohibited to reverse or misconnect the positive and negative poles to avoid damage to the power supply and load equipment; When wiring, ensure that the terminal screws are tightened and the torque is controlled at 5.5 lb inch to prevent looseness that may cause poor contact or heating; The total power of the backend load shall not exceed the rated output power of the power supply (240W), and the load current shall not exceed the rated output current (10A). When multiple loads are connected in parallel, the load shall be reasonably distributed to avoid single circuit overload.
-Standardized installation and environmental protection: The installation location should be away from strong electromagnetic interference equipment such as welding machines and high-power motors to avoid unstable power supply caused by electromagnetic interference; When multiple power supplies are installed side by side, a spacing of ≥ 30mm should be maintained to ensure good heat dissipation; Strictly follow local electrical regulations for installation, and ensure reliable grounding with a grounding resistance of ≤ 4 Ω to prevent the risk of electric shock or electromagnetic interference; Avoid installation in areas with direct sunlight, high temperatures, humidity, or high levels of dust to extend the lifespan of the power supply.
-Professional operation: The parameter setting, system integration, and fault maintenance of modules need to be completed by professional technicians to avoid system failures or equipment damage caused by non professional operations.
