Ideal Power offers surge suppression modules from P-Duke

Power conversion specialist, Ideal Power, has announced the availability of surge suppression modules (SSMs) from Taiwanese manufacturer, P-Duke.

The series of SSMs provide surge protection to protect DC/DC converter modules in railway applications. The SSMs can clamp input surge voltages to a safe level to protect DC/DC converters and enable them to keep working.

They are rated to withstand a 385V DC input surge for 20ms, in compliance with the railway industry’s standard RIA12 for surge susceptibility. Operating input voltage can range from 43 to 160V DC, enabling the SSMs to be used with the 110V battery system typically used in railways.

There are three models in the SSM range, the SSM-110008-001 which can handle power of up to 300W, the SSM-110004-001 is rated at 150W, and the SSM110P50-001 handles up to 20W. The SSM-110008-001 and SSM-110004-001 are in a compact package measuring 1.6 x 1.0 x 0.4-inch (40.6 x 2.54 x 10mm) and the SSM110P50-001 uses an industry-standard DIP24 package, measuring 1.25 x 0.8 x 0.4-inch (31.75 x 20.3 x 10mm).

The SSMs can be used across a wide range of operating ambient temperatures: from -40 to +105 degrees C for the SSM-110008-001 and SSM-110004-001, and from -40 to +95 degrees C for the SSM110P50-001.

The SSMs complement other products for railway applications in the Ideal Power portfolio. The company also offers P-Duke’s RDL03W and RDL06W, which are claimed to be two of the smallest railway DC/DC converters available today. They are approved to the EN 50155 and EN 45545-2 railway standards, and provide 3.0 and 6.0W output power in a SIP8 package. They offer input voltage ranges of 9.0 to 36, 18 to 75 and 43 to 160V DC, which are suitable for the 24, 48, 72, 96 and 110V DC voltages of each kind of railway power system.
