Mean Well LRS-350-5 300W 5V 60A Switching Power Supply

Description Device Overview: Mean Well LRS-350-5 Meet the reliable 5V workhorse for high current DC loads. The Mean Well LRS-350-5 delivers a steady 5V at up to 60A, giving you 300W of regulated power in a low profile enclosed chassis. It is a favorite for digital electronics, LED installs, logic rails, and it is perfect for powering Bitcoin home mining accessories and clusters that run on a 5V rail. You get an enclosed industrial grade PSU with a built in fan, wide AC input range, and the protections you want when you are pushing a lot of current through sensitive hardware. What makes the Mean Well LRS-350-5 stand out Single 5V output rated 60A continuous for 300W total. Universal AC input with a rear selector for 115 or 230 VAC so you can match your mains before first power up. Trim the output from about 4.5V to 5.5V to compensate for cable drop or to meet device requirements. Built in protections for short circuit, overload, over voltage, and over temperature with auto recovery. Temperature controlled cooling with fan on off logic for efficient and dependable operation. Compact footprint about 215 × 115 × 30 mm and roughly 1.0 kg for easy mounting in tight builds. Typical efficiency around 83.5% to reduce waste heat. Low no load power consumption to help systems meet energy requirements. All specs above per the manufacturer datasheet. Mean Well ideal uses Solo Satoshi mining rigs and 5V accessory buses. LED strips, digital signage, controller boards, and logic level gear. Raspberry Pi clusters, micro-controller projects, and 5V powered hubs. General purpose DC benches where a rugged single output supply is preferred.

Always set the AC selector correctly before use. Mean Well Important safety notes Rated output is 5 volts at up to 60 amps which is 300 watts. For continuous duty, plan for no more than about 80% of rating which is roughly 240 watts or 48 amps. Set the input voltage selector to 115 or 230 volts before first power up. Always connect protective earth to the ground terminal. Disconnect AC mains before wiring or touching any terminals. Live contacts can cause serious injury or death. Mount in a ventilated non-conductive enclosure and keep vents and fan clear. The unit will warm under sustained load. Use conductors sized for the current and length. For the main 5V feed use heavy gauge wire sized to carry the total load. For branch circuits use appropriately rated leads and fuse each branch. Use properly crimped ring or fork terminals and tighten terminal screws securely. Verify polarity before energizing. Keep away from liquids, flammables, pets, and children. Indoor dry locations only. Do not short the output or reverse polarity. Do not parallel supplies unless you understand current sharing and use proper ORing methods. Adjust the voltage trim only with an insulated tool and only when it is safe to do so. Installation and servicing should be performed by qualified personnel and in accordance with local electrical codes.
