A device that can provide stable and reliable DC power for various applications. It accepts a wide range of AC input voltage from 90 to 264 V AC or 120 to 375 V DC1. It uses a primary switch mode technology that switches the input voltage on and off at a high frequency, which reduces the size and weight of the transformer and the filter capacitor. It also improves the conversion efficiency, which can reach up to 95%2. It delivers a regulated DC output voltage of 24V and a maximum output current of 15A. It has a ratchet lock mechanism that secures the output voltage and prevents it from changing accidentally It also has a short circuit protection, an overvoltage protection, and an overtemperature protection that ensure the safety of the power supply and the connected devices. It has a fan that is attached to the enclosure, which cools down the internal components and prevents heat accumulation. It also has a fan duct that directs the airflow around the power supply and improves the cooling performance. It is suitable for various applications such as industrial automation, instrumentation, LED lighting, CCTV, PLC, DC motor, fan, pump, heater,
