600W AC/DC power supplies are compact & efficient
Roal Electronics will present the DDP600 series of extremely compact and efficient AC/DC power supplies at electronica 2014 in Munich, and Compamed 2014, in Düsseldorf. The power supplies have been specifically designed for industrial, medical and SSL market segments.
Offering 600W at 24 and 48V single output voltages, the series maintain all functional parameters throughout the 85-305VAC extended range of input voltages. The DDP600 series offers 94% typical efficiency, 2xMoPP medical protection grade, greater than 0.9 PFC at any working condition and 800W peak power for 10s.
High efficiency enables the DDP600 series to generate less heat, which facilitates thermal management in space constrained systems and offers higher reliability. The series feature a built in current share function for parallel operation between power units to enhance total power and allow N+1 redundant operation by adding an OR-ing external circuitry.
The DDP600 series offer a 12VDC auxiliary and +5VDC stand-by as additional outputs. Available control signals include Power Good and Remote On/off. Protection features include high-breaking capacity fuse on both line and neutral, input under voltage lockout, output over-current, output short-circuit, output over-voltage and over-temperature.
The series come in a 4.4x7.3x1.6" form factor and two different packages: a U-shaped chassis and an enclosed one with a built in fan which speed is controlled to assure a proper forced air cooling flow in every working condition, minimising operation noise and enhancing useful life. Both packages can be operated from -20 to +70°C.
The DDP600 is safety certified to IT, Medical and SSL latest standards. The series meets the EN55022 EMC limits of Class B for conducted and radiated emissions as well as the IEC/EN 61000-3 and IEC/EN 61000-4 EMC standards.
