At TRS-STAR GmbH is the new 20W DC-DC train power supply family 98DW-R3 from Yuan Dean Scientific Ltd. (YDS) available with an efficiency of up to 89%.

The compact power modules in a 6-pin DIL housing (50.8 x 25.4 x 10.6mm) are designed in accordance with the EN50155 standard for use in the railway sector and with the 4: 1 ultra-wide input voltage range in 24V, 48V -, 96V and 110V on-board systems can be used.

Depending on the model, the short-circuit proof converters offer single and dual output voltages from 3.3V to 15V with an insulation voltage of 1.6kV input / output to the housing and 3kV from the primary to the secondary connection.

The operating temperature range is -40 ° C to + 85 ° C. The specified output power is available up to an ambient temperature of + 60 ° C without de-rating.

In addition to applications in rail technology, the converters are also suitable for sophisticated solutions in the areas of telecommunications, industrial and network technology, which place particularly high demands on robustness and EMC performance. The manufacturer can adapt to customer-specific requirements.
