{"product_id":"mean-well-hdr-60-5","title":"Mean Well HDR-60-5","description":"\u003ch2\u003eMean Well HDR-60-5 — 5V 6.5A (32.5W) DIN-rail PSU\u003c\/h2\u003e\n\u003cp\u003eAn ultra-slim DIN-rail supply that turns mains into a clean 5V\/6.5A rail. In a 3D-printer build this is the \u003cstrong\u003elow-voltage \/ logic\u003c\/strong\u003e supply, not the main motion supply. It runs a Raspberry Pi (Klipper host), an MCU board, a small display, LED strips, fans, or other 5V accessories that you want on a dedicated rail instead of stealing current from the toolboard or a USB brick.\u003c\/p\u003e\n\u003cp\u003eIt does \u003cstrong\u003enot\u003c\/strong\u003e power a 24V bed heater or 24V steppers — for that you want a 24V unit (the Voron standard). Pair this with your 24V main supply when you want the Pi and electronics on their own isolated, properly-fused source.\u003c\/p\u003e\n\n\u003ch3\u003eWhy the HDR form factor\u003c\/h3\u003e\n\u003cp\u003eHDR is Mean Well's ultra-slim \"step-shape\" DIN-rail line. It clips onto standard 35mm DIN rail (TS-35\/7.5 or TS-35\/15), so if your printer's electronics bay or control cabinet is built around a rail, this drops in clean next to your terminal blocks and breakers — no standoffs, no open-frame chassis to mount. The 52.5mm-wide (3SU) body is narrow, fanless, and silent. Compared to an open-frame LRS brick, you pay a bit more for the cabinet-grade packaging and the tidy rail mount.\u003c\/p\u003e\n\n\u003ch3\u003eThe honest wiring \/ safety reality\u003c\/h3\u003e\n\u003cp\u003eThis is a bare-terminal mains unit. Live AC (L\/N) lands on exposed screw terminals on one end; 5V DC comes off screw terminals on the other. That means:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eYou are responsible for the mains side.\u003c\/strong\u003e It needs an appropriately-rated inline fuse and proper mains wiring (correctly-gauged, strain-relieved, ferrules on stranded conductors). Nothing here is \"plug and play.\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass II \/ no earth pin.\u003c\/strong\u003e The HDR series is double-insulated — there is no protective-earth (PE) terminal on the unit itself. Earth your chassis\/enclosure separately per your build's grounding scheme; do not assume the PSU bonds your frame.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount it where terminals can't be touched.\u003c\/strong\u003e DIN-rail supplies live inside an enclosure for a reason. Keep the AC terminals covered\/inaccessible in the finished build.\u003c\/li\u003e\n\u003cli\u003eIf you're not comfortable terminating mains, stop and get someone who is. The DC side is harmless; the AC side will hurt you.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpec at a glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOutput: 5V DC, 6.5A, 32.5W\u003c\/li\u003e\n\u003cli\u003eInput: 85-264VAC universal, 47-63Hz\u003c\/li\u003e\n\u003cli\u003eEfficiency ~85% (typ.), fanless free-air cooling\u003c\/li\u003e\n\u003cli\u003eOperating temp -30C to +70C\u003c\/li\u003e\n\u003cli\u003eOutput adjustable ~5.0-5.5V (up to ~+10%) via onboard trimmer\u003c\/li\u003e\n\u003cli\u003eShort-circuit \/ over-current (hiccup) \/ over-voltage protection\u003c\/li\u003e\n\u003cli\u003eMounts on TS-35 DIN rail; 52.5 x 90 x 54.5mm (W x H x D); ~0.19kg\u003c\/li\u003e\n\u003cli\u003e3-year Mean Well warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThis unit is on sale as part of a clearance — same genuine Mean Well part, lower price.\u003c\/p\u003e","brand":"MEAN WELL USA Inc.","offers":[{"title":"Default Title","offer_id":44779849908446,"sku":"7977873823","price":18.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0556\/9767\/0313\/files\/hdr-60-5.jpg?v=1707759483","url":"https:\/\/formosissima.myshopify.com\/products\/mean-well-hdr-60-5","provider":"dfh.fm","version":"1.0","type":"link"}
