DC-DC Modules for Railway Apps Offer Nominal 24 V to 110 VDC Input Range

Mon, 12/21/2009 - 10:40am

DCDC converters for railwaysMartek Power introduced its CMS120 Series of 120W DC/DC modules designed for worldwide railway applications. The modules meet all relevant railway standards including EN50 155 and work across a broad operating temperature range without derating. Designed to be PCB mounted, CMS Series modules measure 92 mm x 45 mm, are 20 mm high and include an integral extruded aluminium heat sink. PCB connection is by 1.5 mm diameter pins. According the company, the new modules can be integrated into a customer’s own power supply design using a minimum of external components. However, users can also use Martek Power to develop a custom power solution based around the CMS120 modules as “building blocks”. The new DC/DC modules accept a very wide range of input voltages across two versions. The low input version has range from 12 V to 50.4V DC with nominal inputs of 24 V and 36 VDC. The high input version has a range from 43.2 V to 154V DC with nominal inputs from 72 V to 110VDC. Output voltages are 12 V and 24 V.
