For applications that are subjected to severe over-voltage transients, RECOM has developed a range of surge protection modules for PCB mounting that are conform to the RIA12, NF F 01-510 and EN50155 specifications for railway rolling stock, or to the MIL-STD-416G or MIL-STD-1275E surge protection military standards. The RSP series are designed to be inserted before the EMI input filter stage so that both the filter components and the following DC/DC converters are protected against high energy over-voltage surges and transients.
The RSP series are available in 20W, 45W, 150W, 200W or 300W continuous power ratings for either 110VDC or 24/28VDC nominal input voltages. The surge protector output tracks the supply voltage (pass-through) in the range of 40 to 165VDC or 9 to 36VDC, but then clamps the output voltage to 168 or 40VDC respectively. The RSPxx-40M series additionally feature built-in inrush current limiting and an on/off control, while the RSPxxx-168 series can handle input voltage surges of up to 385VDC.
