350W Enclosed AC-DC Power Supply with Anti-Rain Splash Design

In response to the demands of LED lighting applications for channel letters and advertising signs, MEAN WELL Enterprises Co. Ltd. launched a new family of enclosed ac-dc power supplies with constant voltage output and anti-rain splash design, the ERP-350 Series. With aluminum enclosure and heat dissipation holes with anti-rain splash design, ERP-350 is designed to be installed in outdoor environments with suitable canopy coverage. All series are semi-potted by glue on the PCB. They provide the ability of heat dissipation and protection for internal electronic components against dust and moisture as well as shock absorption to withstand 3G vibration.

With economical circuit design, ERP-350 features with 180 to 264 Vac input range and offers 24Vdc/36Vdc/48Vdc output voltage for selections. Possessing up to 90% of working efficiency, ERP-350 series can be cooled by free air convection from -30 to +40 degrees C ambient temperature, and even up to +60 degrees C by suitable derating. Other built-in standard functions include trimming output voltage (±10%), protections for short circuit, over load, over voltage and over temperature.

These power supplies include an LED indicator for power on. They have several safety certifications including: IEC60950-1, UL60950-1, and CQC GB4943.1(pending). They measure 220.4mm x 130mm x 48mm and are offered with a three-year warranty. Target applications include LED channel letters, decorative lighting by using LED strips, and LED displays, and so on.
