RWR 350-P600, Railway DC-DC converters protect traction and rolling stock equipment from transients and surges in DC control systems
The RWR 350-P600 series is a recent addition to our line of fully encapsulated RIA12 railway quality DC-DC converters. The units have an input voltage surge withstand capacity 3.5 times nominal input voltage for 20 milliseconds and meet the requirements of RIA12 with wide margins. RIA12 is the general specification for protection of traction and rolling stock equipment from transients and surges in DC control systems.
The RWR 350-P600 converters meet the requirements of EN50155 for electronic equipment used on railway rolling stock. They are equipped with heavy filtering on the input and output and comply with EN50121-3-2. They also meet EN61000-4-2 (ESD), EN61000-4-3 (RF Immunity), EN61000-4-4 (Fast Transients) and EN61000-4-6 (Conducted Immunity). Other protection includes 3000Vdc input-output isolation, overload protection, thermal protection and current limiting.
The 350W railway converters provide a single, regulated output of 24Vdc, 36Vdc, 48Vdc or 110Vdc. They accept wide input ranges including 14.4-34V (24Vdc nominal), 36Vdc (22-51V), 29-67V (48Vdc), 43-101V (72Vdc) or 66-154Vdc (110Vdc). Custom input and output voltages are available. Regulation is 1% from no load to full load across all line and load conditions. Efficiency depends on input/output configuration and is typically between 80 to 90% at full load.
The RWR 350-P600 converters are fully encapsulated with a thermally conductive MIL-grade silicon rubber compound with a UL94V-0 flammability rating. Encapsulation ensures protection from high levels of shock and vibration, moisture, dust, salt fog and other contaminants. Conduction cooling via base plate to customer heat-sink or chassis as well as the encapsulation enable operation over a -40°C to +70°C temperature range for full specification without derating. The railway converters are housed in rugged, encapsulated P600 type chassis measuring 155 x 72 x 269 mm.
