Roal Electronics new DDP600 series of compact, efficient, industrial and medical grade, 600 Watts AC-DC power supplies.


Roal Electronics SpA will be presenting its new DDP600 series of extremely compact and efficient ac-dc power supplies simultaneously at the “Compamed 2014”, Düsseldorf, this November.

The new DDP600 series, has been specifically designed to meet the widest application requirements in the Industrial, Medical and SSL market segments. Offering 600 Watts at 24 and 48V single output voltage, the series keep unchanged all functional parameters throughout the 85 - 305 VAC extended range of input voltages. A 94% typical efficiency, 2 x MoPP medical protection grade, a greater than 0.9 PFC at any working condition and a 800 Watts peak power for 10 seconds, are the DDP600 series key characteristics.

The series come in a 4.4 x 7.3 x 1.6 inches 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 minimizing operation noise and enhancing useful life. Both package can be operated at the -20 – 70°C temperature range. Further variants, part of the product range, will be released to meet the system integrators demands.

Operating at 94% typical efficiency, the DDP600 series generate less heat which facilitate thermal management in space constrained systems and offer higher reliability.

The DDP600 series offer a 12VDC auxiliary and +5VDC stand-by as additional outputs. Available control signals include Power Good and Remote On/off.

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.

Protection features include High-Breaking capacity fuse on both Line and Neutral, input under voltage lockout (IUV), output over-current (OC), output short-circuit (SC), output over-voltage (OV) and over-temperature (OT).

ROAL Electronics will present the new DDP600 series of power supplies simultaneously at Electronica (Hall B2, booth 268) and Compamed (Hall 8b, Booth K31) this November, to reassert its innovative design skills and valuable long experience which translate into cost effective solutions, suitable for the most diverse applications and still representing the state-of-the-art in terms of power density and efficiency.

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.
