ABSOPULSE Electronics has recently added the RWR-350-P600 series to its line of fully encapsulated RIA12 railway quality DC-DC converters. The units have an input voltage surge withstand capacity 3.5 times the 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. They are equipped with heavy filtering on the input and output and comply with EN50121-3-2. They also meet EN61000-4-2, EN61000-4-3, EN61000-4-4 and EN61000-4-6. 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 24Vdc (14.4-34V range), 36Vdc (22-51V), 48Vdc (29-67V), 72Vdc (43-101V) or 110Vdc (66-154Vdc). Custom input and output voltages are available.
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 allow for operation over a -40°C to +70°C temperature range for full specification without derating. The units are housed in compact, encapsulated chassis measuring 155 x 72 x 269 mm.
ABSOPULSE offers a broad selection of RIA12 railway quality DC-DC converters with power ratings from 30W to 500W.
