One PSU failure takes down the whole rack of converters, and your network goes dark at 2am. The MCRP100 is the redundant power module for the TL-MC1400 14-slot chassis. It converts 100-240V AC (50/60Hz) into a steady 9.5V DC output rated at 102W, with over-voltage, short-circuit, and over-current protection on the output side. Dimensions are 210 × 130 × 70mm, so it slots into the chassis without rerouting cables. Operating range is 0 to 60°C, which covers a server room or an unheated IT closet. If your TL-MC1400 is running on a single supply, this is the piece that keeps it alive when one unit fails. Add to cart and keep that redundancy in place
