Absopulse Electronics’ RWY 252H series 250W, dual-output encapsulated DC/DC converter is designed for use in the railway and other severe environments. It features:
- Rugged, field-proven design
- Fully independent, dual output
- Full encapsulation
- Wide temperature range
- Full electronic protection
- EN50155 input ranges
The RWY 252H series converters use high-efficiency power conversion technology to deliver a complete 250W power solution from a compact 113mm x 60mm x 200mm enclosure. The converters meet EN50155 for electronic equipment used on railway rolling stock, and are suitable for many railway applications including wireless communication systems, Wi-Fi, video monitoring, PA systems and certain control systems. The units may also be used in industrial, mining, military, and marine applications, and other extreme environments.
The RWY 252H converters have two fully independent, regulated, isolated output stages, each providing any single voltage between 5V and 110Vdc. Output V1 has a 140W power capacity and output V2 has a 110W power capacity. Nominal input voltages are 24V, 36V, 48V, 72V, 96V or 110Vdc with EN50155 input ranges.
Efficiency is typically 85% at full load, depending on the input/output configuration. Protection features include 3000Vdc input/output isolation, reverse polarity protection, overload protection and current limiting. An optional LED can be installed to indicate an output ‘ON’ condition.
The series operates within a -40°C to +70°C cold plate temperature range for full specification. The units are entirely encapsulated with a thermally conductive MIL-grade silicon rubber compound which provides immunity to high levels of shock and vibration (EN61373/IEC61373), moisture, dust and airborne contaminants.
They meet EN50121-3-2 and EN55022 Class B conducted and radiated EMI, and relevant EN61000 immunity standards, ensuring minimum interference with sensitive electronic equipment. Low component count, large design headroom, and the use of components with established reliability result in a high MTBF, and contribute to low life-cycle costs of the units.
Absopulse offers an extensive range of railway and industrial quality power supplies designed for operation in severe environments. These designs can readily be modified to meet customer specified electrical and mechanical requirements. We also provide fully-custom solutions with short delivery times and low set-up costs.
