However, in some display\nconfigurations, a low power 5V was also needed. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Their local TDK-Lambda salesperson suggested the\n800W <a href=\"https:\/\/blog.uk.tdk-lambda.com\/uk\/category\/products\/qm\/\">QM5 series of modular power\nsupplies<\/a>. One part number was configured with 12V and 24V output modules, and a\nsecond part with an extra module fitted for the 5V output.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The high efficiency QM series offers very low\naudible noise, short lead-times and is backed with a 7-year warranty for lower\ncost of ownership.
