It is particularly suitable for addressable 5V LED strips such as WS2812B and SK6812, for LED pixels, matrices and displays, as well as for microcontroller projects with ESP32, Arduino or Raspberry Pi. With its power, it is ideal for large installations.\u003c\/p\u003e\n\u003cp\u003eThe power supply operates with a typical efficiency of 83.5% and reliably protects your installation against short circuits, overloads, overvoltage and overtemperature. The output voltage can be finely adjusted from 4.5 to 5.5 V via a potentiometer to compensate for voltage drops on the supply line. The input voltage is set to 230 V (Europe) or 115 V via a selector switch. A temperature-controlled fan ensures safe temperatures even at full load and usually remains off at partial load. As a branded power supply from the proven LRS series, it offers a very long service life and a 3-year manufacturer's warranty.\u003c\/p\u003e\n\u003ch3\u003eTechnical Data Mean Well LRS-350-5\u003c\/h3\u003e\n\u003ctable style=\"width: 100%;\"\u003e\n\n\u003ctbody\u003e\n\n\u003ctr style=\"background-color: #e6e6e6;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eManufacturer \/ Model\u003c\/td\u003e\n\n\u003ctd\u003eMean Well LRS-350-5\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #f2f2f2;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eOutput Voltage\u003c\/td\u003e\n\n\u003ctd\u003e5 V DC\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #e6e6e6;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eOutput Voltage Adjustment Range\u003c\/td\u003e\n\n\u003ctd\u003e4.5 to 5.5 V (Potentiometer)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #f2f2f2;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eOutput Current\u003c\/td\u003e\n\n\u003ctd\u003e0 to 60 A\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #e6e6e6;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eRated Power\u003c\/td\u003e\n\n\u003ctd\u003e300 W\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #f2f2f2;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eInput Voltage\u003c\/td\u003e\n\n\u003ctd\u003e90 to 132 V AC \/ 180 to 264 V AC (selectable via switch), 240 to 370 V DC\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #e6e6e6;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eEfficiency (typ.)\u003c\/td\u003e\n\n\u003ctd\u003e83.5%\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #f2f2f2;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eVoltage Tolerance\u003c\/td\u003e\n\n\u003ctd\u003e±3%\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #e6e6e6;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eRipple \u0026amp; Noise\u003c\/td\u003e\n\n\u003ctd\u003emax. 150 mVp-p\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #f2f2f2;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eProtection Features\u003c\/td\u003e\n\n\u003ctd\u003eShort circuit, overload, overvoltage, overtemperature\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #e6e6e6;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eCooling\u003c\/td\u003e\n\n\u003ctd\u003eTemperature-controlled fan (switches on at approx. 50 °C)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #f2f2f2;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eOperating Temperature\u003c\/td\u003e\n\n\u003ctd\u003e-25 °C to +70 °C\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #e6e6e6;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eHumidity\u003c\/td\u003e\n\n\u003ctd\u003e20% to 90% relative humidity, non-condensing\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #f2f2f2;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eProtection Rating\u003c\/td\u003e\n\n\u003ctd\u003eIP20 (indoor use only)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #e6e6e6;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eConnection\u003c\/td\u003e\n\n\u003ctd\u003eScrew terminal block\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #f2f2f2;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eDimensions (L x W x H)\u003c\/td\u003e\n\n\u003ctd\u003e215 x 115 x 30 mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #e6e6e6;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eWeight\u003c\/td\u003e\n\n\u003ctd\u003eapprox. 760 g\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #e6e6e6;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eSafety\u003c\/td\u003e\n\n\u003ctd\u003eIEC\/EN\/UL 62368-1, CE, RoHS\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr style=\"background-color: #f2f2f2;\"\u003e\n\n\u003ctd style=\"width: 40%;\"\u003eWarranty\u003c\/td\u003e\n\n\u003ctd\u003e3-year manufacturer's warranty\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/tbody\u003e\n\n\n\u003c\/table\u003e\n\u003ch3\u003eFrequently Asked Questions about the Mean Well LRS-350-5\u003c\/h3\u003e\n\u003ch4\u003eHow many LEDs can I power with the LRS-350-5?\u003c\/h4\u003e\n\u003cp\u003eThe LRS-350-5 delivers up to 60 A. If you calculate around 60 mA per WS2812B LED at full white brightness and plan for a 20% reserve, it powers approximately 800 LEDs. This corresponds to around 13.3 m of LED strip with 60 LEDs\/m. In everyday use with colors, effects, or dimmed brightness, the consumption is usually significantly lower.\u003c\/p\u003e\n\u003ch4\u003eIs the LRS-350-5 suitable for WS2812B, SK6812, and other addressable LED strips?\u003c\/h4\u003e\n\u003cp\u003eYes. The power supply delivers a stable 5 V DC and is suitable for all 5V LED strips and pixels, for example WS2812B, SK6812, WS2811 (5V), APA102, SK9822, as well as 5V single-color strips. For control, you additionally need a suitable controller, such as a WLED controller or a microcontroller like ESP32 or Arduino.\u003c\/p\u003e\n\u003ch4\u003eCan I adjust the output voltage?\u003c\/h4\u003e\n\u003cp\u003eYes. Via the potentiometer next to the terminals, the voltage can be adjusted from 4.5 to 5.5 V. This allows you to compensate for a slight voltage drop on the supply line. Set the voltage with a measuring device and try not to exceed 5.2 V at the LED strip.\u003c\/p\u003e\n\u003ch4\u003eWhat do I need to consider with the voltage selector switch?\u003c\/h4\u003e\n\u003cp\u003eThe LRS-350-5 has a selector switch for 115 V or 230 V input voltage. For operation on the German and European power grid, the switch must be set to 230 V before the first switch-on. An incorrect setting can damage the power supply.\u003c\/p\u003e\n\u003ch4\u003eIs the power supply loud?\u003c\/h4\u003e\n\u003cp\u003eThe LRS-350-5 has a temperature-controlled fan. It only switches on at an internal temperature of around 50 °C and switches off again below around 40 °C. At partial load and with good ventilation, the power supply therefore often runs without fan noise.\u003c\/p\u003e\n\u003ch4\u003eHow often do I need to inject power into 5V LED strips?\u003c\/h4\u003e\n\u003cp\u003eAt 5 V, high currents flow, which is why the voltage drops faster on the strip than at 12 V or 24 V. As a rule of thumb, you should inject power into 5V LED strips again approximately every 2 to 3 meters and use sufficiently thick supply lines. This prevents color shifts towards red and uneven brightness.\u003c\/p\u003e\n\u003ch4\u003eIs the LRS-350-5 dimmable or waterproof?\u003c\/h4\u003e\n\u003cp\u003eNo. It is a constant voltage power supply without a dimming function. Dimming is done via the LED controller on the output side. With a protection rating of IP20, the power supply is only intended for dry indoor spaces, control cabinets, or enclosures.\u003c\/p\u003e\n\u003ch4\u003eWhy a Mean Well power supply?\u003c\/h4\u003e\n\u003cp\u003eMean Well is one of the world's leading manufacturers of switching power supplies. The LRS series is a proven industry standard with a long service life, tested safety according to IEC\/EN\/UL 62368-1, low ripple, and a 3-year manufacturer's warranty. Especially for 5V projects with high currents, a power supply with a clean, stable output voltage pays off.\u003c\/p\u003e\n\u003ch3\u003eMean Well LRS 5V Series at a Glance\u003c\/h3\u003e\n\u003cp\u003eDo you need more or less power?
