DC-DC converters

2 May 2012 Power Electronics / Power Management

Mean Well has expanded its range of DC-DC converters with three new models covering power levels from 3 W to 60 W.

The SPU03 is a 3 W device in a single-in-line package measuring 19,5 x 7,62 x 10 mm. It exhibits up to 88% efficiency and can operate in ambient temperatures of


-40°C to +90°C. Equipped with a standard pin assignment, it features 3000 V d.c. input/output isolation, low ripple noise, CE/FCC compliance and built-in short circuit protection, making it very suitable for industrial control, telecom/datacom and distributed power architecture applications.

The 30 W SKM30 series is housed in a 5 x 2,5 x 11 mm dual-in-line package and possesses up to 90% efficiency over the -40°C to +55°C temperature range, and can operate in up to +75°C with derating. Equipped with a standard pin assignment, the series features 2:1 input range, 1500 V d.c. input/output isolation, short circuit/overload/input and output over-voltage protection, low ripple noise, built-in remote on/off control and output trimming.

The SKM30’s six-sided, shielded metal case enables it to comply with CE/FCC regulations without adding extra EMC suppression components. The fully encapsulated packaging can help it withstand the influence of dust and moisture in harsh environments, making it suitable for industrial control, telecom/datacom and distributed power architecture.

Finally, the dual-in-line 60 W converters of the SKA60 range are designed to comply with the standard pin assignment in the market. Standard features include 2:1 wide input range, 1500 V d.c. input/output isolation, short circuit/overload/over-voltage protection, low ripple noise, remote on/off control, remote sense and trimming output (±10%). In addition, without adding additional EMC suppression components, they can comply with CE/FCC Class A requirements.

The SKA60 devices have up to 93% efficiency and can be operated at full load without any heatsink installed from -40°C to +55°C, and up to +70°C with derating. Fully encapsulated packaging aids the converters’ heat dissipation ability and allows them to withstand the influence of dust and moisture in harsh environments, meaning they are suitable for industrial control, telecom/datacom, vehicle, vessel, backup systems and any application that uses rechargeable batteries as the power source.
