TRWBH10 Series DC-DC Converters for Railway Applications

TRWBH10 Series single- and dual-output DC-DC converters with a wide 4:1 input range provide 10 watts of power with no minimum load required. Offering efficiencies as high as 87.5 percent, 3,000V AC isolation voltage, low standby power, remote ON/OFF and an internal EN 55032 Class A filter, these DC-DC converters are well-suited for railway applications. The compact units measure 1.25 x 0.8 x 0.42 inches (31.8 x 20.3 x 10.66 millimeters). Built-in safeguards include overcurrent, overvoltage, undervoltage and short circuit protection. TRWBH10 DC-DC converters meet the IEC/EN/UL 62368-1 safety standard and comply with RoHS and REACH regulations.

Note

  1. The TRWBH-110 recommended 2 pcs of aluminum electrolytic capacitor (Nippon chemi-con KY series, 220μF/200V) and a TVS (SMDJ220A, 220V, 600Watt peak pulse power) in parallel.

CAUTION: This power module is not internally fused. An input line fuse must always be used.
