    Q1: Is the output of the 18V-40V to 24V converter stable and reliable?

    Yes, the DC-DC boost and buck converter has a built-in closed-loop voltage regulation system to ensure that the output voltage is within 24V ±1%. Regardless of the input voltage fluctuation, the converter can respond quickly to ensure that the load equipment is not affected. Meanwhile, it is equipped with over-current, short-circuit, over-temperature and other protection functions, which is suitable for long-time continuous work.

    Q2: What is the installation and heat dissipation method of this 24v DC converter?

    The module usually adopts free convection heat dissipation without fan, which is suitable for closed or space-limited industrial equipment internal use. The product shell is mostly made of aluminum alloy with high protection level, which has certain dustproof and waterproof performance. Installation is generally screw-fixed or rail-mounted, with input and output cables for quick integration into the system.
