Notes on industrial power selection Power matching: Accurately calculate the power requirements of load equipment, including startup power (some equipment starts up with high current, and the power is higher than the normal operating power) and continuous operating power. The rated power of the industrial power supply should be greater than the total load power, and a certain margin (generally 10% - 20%) is reserved to deal with possible peak power requirements, ensure that the power supply is stable and avoid overload damage. Voltage and current output: According to the requirements of the load equipment, select an industrial power supply with the output voltage and current in compliance with the specifications. Pay attention to voltage accuracy and current stability. For equipment that is sensitive to voltage fluctuations, a power supply with a small voltage adjustment rate must be selected; for large current loads, it is necessary to ensure that the power supply can provide a continuous and stable large current output and has an overcurrent protection function. Working environment adaptability: Consider the use environment of industrial power supply, such as temperature, humidity, altitude, electromagnetic interference and other factors. In high temperature environments, choose a power supply with good heat dissipation design and a wide temperature working range; in high humidity or dust environments, a power supply with protection level (such as IP level) needs to meet the requirements; in strong electromagnetic interference environments, choose a power supply with strong anti-interference ability. Power efficiency: Pay attention to power conversion efficiency. High-efficiency power supply can reduce energy consumption, reduce operating costs, and reduce heat generation, improving power supply stability and service life. For example, in industrial applications with long-term continuous operation, selecting power supplies with a conversion efficiency of more than 90% can significantly save energy. Protection function: Industrial power supplies should have complete protection functions, such as overvoltage protection (OVP), overcurrent protection (OCP), short circuit protection (SCP), overheating protection (OTP), etc., which can cut off the power supply in time when abnormal situations occur to protect the safety of the load equipment and the power supply itself.
