It delivers 200 W at 12 V, or 16.7 A of continuous current, from a sealed metal case with no fan inside. That combination \u2014 real power, zero noise and a failure rate we can count on one hand \u2014 is why it sits under most of our own pixel LED installations.<\/p>\n<p><img decoding=\"async\" src=\"\/wp-content\/uploads\/meanwell-rsp-200-12-power-supply.webp\" alt=\"Meanwell RSP-200-12 fanless 12V 200W power supply for WS2815 pixel LED strip\" width=\"800\" height=\"450\" loading=\"lazy\" \/><\/p>\n<h2>Why the RSP-200-12 is our default 12 V supply<\/h2>\n<p>We do not pick a power supply on price. We pick it on the number of service calls it does not generate. On both counts the RSP-200-12 has earned its place in our stock.<\/p>\n<h3>Completely silent, because there is no fan<\/h3>\n<p>The unit is cooled by free air convection. Nothing spins, so nothing hums, whines or clogs with dust. In a studio, a showroom, a museum or a hotel lobby that matters more than any spec on the label, because a fan is the one part of a power supply your client can hear.<\/p>\n<h3>More than 1000 RSP-200-12 sold, two with a problem<\/h3>\n<p>We have shipped over a thousand of these supplies. Two came back with a fault. That is our own field record, not a manufacturer claim, and it is the reason we keep reordering the same model instead of chasing a cheaper one.<\/p>\n<h2>Powering WS2815 pixel LED strip with the RSP-200-12<\/h2>\n<p>The RSP-200-12 is a natural match for WS2815, which runs on 12 V and therefore loses far less voltage along a run than a 5 V strip. One supply covers a serious length of tape with a single AC feed.<\/p>\n<h3>Sizing the supply against your run<\/h3>\n<p>Add up the maximum draw your strip manufacturer states per metre, multiply by your length, and keep roughly 20 % headroom. If the total goes past 16.7 A, split the run and add a second supply with power injection rather than pushing one unit to its limit.<\/p>\n<h2>RSP-200-12 electrical specifications<\/h2>\n<ul>\n<li>Output: 12 V DC, 16.7 A, 200 W<\/li>\n<li>Input: 88\u2013264 V AC, 47\u201363 Hz, with active power factor correction<\/li>\n<li>Efficiency: 89 %<\/li>\n<li>Cooling: fanless, free air convection<\/li>\n<li>Protections: short circuit, overload, over voltage, over temperature<\/li>\n<li>Working temperature: \u221230 \u00b0C to +70 \u00b0C<\/li>\n<li>Connection: screw terminal block, with a power-on LED<\/li>\n<li>Case: 215 \u00d7 115 \u00d7 30 mm, 800 g<\/li>\n<\/ul>\n<p>Full manufacturer data is in the <a href=\"https:\/\/www.meanwell-web.com\/content\/files\/pdfs\/productPdfs\/MW\/RSP-200\/RSP-200-spec.pdf\" target=\"_blank\" rel=\"noopener\">official RSP-200 datasheet<\/a>.<\/p>\n<h2>Built to sit in a rack, 30 mm tall<\/h2>\n<p>At 30 mm tall the case fits a 1U slot, so a row of supplies takes one shelf instead of three. The universal 88\u2013264 V AC input means the same unit works on tour anywhere in the world, and active PFC keeps the load kind to the circuit it shares.<\/p>\n<h3>When several supplies share one breaker<\/h3>\n<p>Every switch-mode supply draws a short current peak at switch-on. Stack enough of them on one circuit and the peaks add up until the breaker trips. Our <a href=\"\/product\/ac-delay\/\">AC Delay<\/a> module staggers the start times so that never happens.<\/p>\n<h2>RSP-200-12 protection and warranty<\/h2>\n<p>Short circuit, overload, over voltage and over temperature protection are all built in, so a wiring mistake on site stops the supply rather than destroying it. The unit carries UL 62368-1, CE and RoHS approval and comes with Meanwell&#8217;s three-year warranty. Pair it with a <a href=\"\/product\/lec-3\/\">LEC 3<\/a> or an <a href=\"\/product\/spi-led-controller\/\">SPI LED Controller<\/a> running <a href=\"\/led-strip-studio-software\/\">LED Strip Studio software<\/a>, and ask our <a href=\"\/support\/\">support team<\/a> if you are unsure how much strip one supply will carry.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The RSP-200-12 is the power supply we reach for most often.
