RWY 200-HSA-P2 encapsulated railway DC-DC converters offer pure convection cooling by heatsink fins and flexible mounting options
The RWY 200-HSA-P2 series is a recent addition to our line of fully encapsulated railway quality DC-DC converters with pure convection cooling. The 200W converters are cooled by a heatsink assembly attached to their under-surface. This ensures operation over -40 to +55oC temperature range for full specification without derating; wider temperature ranges are available on request.
The heatsink assembly can be mounted to a chassis or DIN-rail. The chassis-mounted option is suitable for applications in which a suitable heatsinking surface is not available and only convection cooling will suffice. The heatsink assembly is also suitable for mounting on thermally non-conductive surfaces such as wood, plastic and brick walls.
All RWY 200-HSA-P2 units are shipped with DIN-rail clips, providing customers with the option of both chassis and DIN-rail mounting.
The RWY 200-HSA-P2 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. Encapsulation also provides heat dissipation throughout the module.
The 200W railway converters deliver a single, regulated output of 12Vdc, 24Vdc, 36Vdc, 48Vdc or 110Vdc. They accommodate a broad range of battery and bus distribution voltages while operating with wide input voltage tolerances. Inputs ranges comply with EN50155 and include 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.
The 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. The units 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.
