RECOM – RPA150Q – 16:1 input DC/DC converter for Railway Applications
The new RPA150Q series of RECOM is a 16:1 ultra-wide input high-isolation quarter-brick DC/DC converter, ideal for railway and other harsh industrial applications. Input range of the RPA150Q series is 14.4V to 170V (200V for 1s) and fully regulated available outputs are 12, 24, or 54VDC with wide +10/-20% trim range (+18/-20% for 24V output). Efficiency is high across the operating range, and with sufficient airflow, 150W output is available from -40°C up to at least 65°C for every variant, or to 75°C at least with baseplate cooling. With derating, operation to a baseplate temperature of 105°C is possible.
The product features 4.242kV/1 min reinforced isolation with safety certifications to EN/UL 62368-1 and CAN/CSA-C22.2 N0. 62368-1 up to 5500m altitude, along with functional and safety compliance to railway standards EN 50155 and EN 45545-2. EMC standards EN 55022 and EN 55011, along with EN 50121-3-2 for rail applications can be met with external filtering. The product is fully featured with trim, remote sense, and remote on/off control. Protection includes under-voltage lockout, over-temperature, and output over-voltage/over-current.
The RPA150Q series will operate down to 12V and up to 200V for one second, allowing for dips and surges across various nominal voltages from 24V to 110VDC defined by rail standards EN 50155 and RIA12, with some margin. To suit the typical high shock and vibration rail environment, the product complies with EN 61373 and includes threaded inserts for secure mounting to a PCB or bulkhead. In industrial applications, the compact quarter brick size is useful in space-constrained designs requiring very wide input range.
