CMS120 dc-dc converters for railway applications
A new series of 120W DC/DC modules designed specifically for worldwide railway applications is announced by Martek Power. The CMS120 Series will interest designers of railway power supplies since they feature a very wide input voltage range, 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 are compact, measuring 92 x 45mm and just 20mm high - including an integral extruded aluminium heatsink. PCB connection is by 1.5mm diameter pins.
According to Martek Power, the new modules can be easily 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”. Since the modules are available and already qualified to railway standards, this can provide a faster and more reliable route to market.
The new DC/DC modules accept a very wide range of input voltages across two versions. The low input version has range from 12 to 50.4VDC with nominal inputs of 24 and 36VDC. The high input version has a range from 43.2 to 154VDC with nominal inputs from 72 to 110VDC. Output voltages are 12 and 24V. Operating temperature range is -40ºC to +85ºC.
Under nominal conditions, the modules are 90% efficient and incorporate over-voltage and short circuit protection.
