DIN rail power supply

May 2009 Electrical Power & Protection

Mean Well has launched the second series of its slim DIN rail product family – SDR-480 – to meet the growing demand for high performance DIN rail power supplies in the market. Featuring 94% efficiency, it can provide 480 W continuously with headroom of 720 W for 3 seconds at ambient temperatures up to 60°C cooled only by free air convection. With built-in active PFC function, SDR-480 is a full input range switcher that fulfils the requirement of EN61000-3-2 for harmonic current. The slim design, 85,5 mm in width, helps save space on the rail and also makes it 50% smaller in size compared to its predecessor.

Other standard functions include DC OK relay contact, LED indicator, and protection for short-circuit, overload, over-voltage, and over-temperature. To fulfil the requirements of marine and semiconductor-related usage, SDR-480 also complies with GL and SEMI F47 norms in addition to UL, CUL, TUV, and CE certificates. Suitable applications are factory automation, semiconductor fabrication equipment, marine-related installation, and electro-mechanical applications with medium to high power demand.
