RECOM is launching its 16:1 ultra-wide input high-isolation quarter-brick DC/DC converter, ideal for rail and harsh industrial applications. The input range of the RPA150Q series is 14.4 V to 170 V (200 V for 1 s), and fully regulated available outputs are 12, 24, or 54 VDC with wide +10/−20% trim range (+18/−20% for 24 V output).
Efficiency is high across the operating range, and with sufficient airflow, 150 W output is available from −40°C up to at least 65°C for every variant, or to at least 75°C with baseplate cooling. With derating, the operation to a baseplate temperature of 105°C is possible.
Rail standards EN 50155 and EN 45545-2
Protection includes under-voltage lockout, over-temperature, and output over-voltage/over-current
The product features 4.242 kV/1 min reinforced isolation with safety certifications to EN/UL 62368-1 and CAN/CSA-C22.2 No. 62368-1 up to 5500 m altitude, along with functional and safety compliance to rail standards EN 50155 and EN 45545-2.
EMC standards EN 55032 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.
RPA150Q series
Compact quarter brick size is useful in space-constrained designs requiring a very wide input
The RPA150Q series will operate down to 12 V and up to 200 V for one second, allowing for dips and surges across various nominal voltages from 24 V to 110 VDC 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 a very wide input range.
Industrial applications
“Our RPA150Q series is ideal for rail and harsh industrial applications,” commented Matthew Dauterive, DC/DC Product Manager of RECOM.
“The ultra-wide input range means only one part in the standard quarter-brick format can be used to cover multiple nominal inputs and their surges and transients.”
