LED power supply for outdoor applications
Responding to increasing demand for LED lighting applications, such as channel letters and advertising signs, MEAN WELL have introduced the ERP-350 series enclosed type power supplies. Featuring an aluminium enclosure and heat dissipation holes with anti-rain splash design, the power supplies are suitable for applications including LED channel letters, decorative lighting by using LED strips, and LED displays.
Operting over a temperature range from -30 to +60℃, the ERP-350 series features an input range of 180-264V ac, output voltage selections of 24, 36 or 48V dc, and efficiency of up to 90%. Semi-potted by glue on PCB, the series offers good heat dissipation, protection for internal electronic components against dust and moisture as well as withstanding up to 3G vibration. Therefore the power supplies are suit installation in outdoor environments with suitable canopy coverage.
Standard built-in functions include trimming output voltage (±10%), LED indicator for power on, cooling by free air convection, and protections for short circuit, over load, over voltage and over temperature. Supplied with dimensions of 220.4x130x48mm, the ERP-350 series has been certified to IEC60950-1, UL60950-1, and CQC GB4943.1 (pending) to ensure user safety.
