Miniature 6W Railway DC/DC Converters
MicroPower Direct announced the MR0611S series of single-output 6W converters packaged in a compact 1 x 1 inch case. They are designed to provide the ultra wide input range, robust filtering, rugged packaging and high reliability required for railway/transit applications.
Four standard models operate from wide 40 VDC to 160 VDC (110 VDC nominal) 4:1 inputs, providing tightly regulated single outputs of 5, 12, 15 or 24 VDC. Standard features include line/load regulation less than 1.0%, input/output isolation of 1,500 VDC, and efficiency to 85%. All models are protected for output short circuit faults and output over current faults. The MTBF (per MIL HDBK 217F) is greater than 1.0 Mhours.
The MR0611S family is packaged in a compact 1 x 1 x 0.46 inch case. The pin-out is industry standard. Operation is specified for the wide industrial temperature range of -40°C to +85°C. All models are available on an adapter to allow mounting to a chassis.
The MR0611S series is has been designed for use in rail and transit applications. They provide the high reliability, compact size, wide temperature operation and compliance to standards required for use in rail equipment.
All MicroPower Direct products are designed to provide long, reliable field life. Considerable attention is given to the proper selection, derating, and layout of all circuit components. In addition, extensive reliability screening is also performed on all modules as a routine part of the production process.
