Fully potted DC-DC converters in a standard quarter-brick package, rated at 40, 60 and 150 W: RQB40W12, RQB60W12 and RQB150W12 (14–160 V DC input) and RQB150W3 (60–160 V DC input). Datasheets declare EN 50155 supply class S2, EN 61373 for shock and vibration, and EN 50121-3-2 for electromagnetic compatibility; EN 45545-2 compliance is confirmed in the datasheet for RQB60W12.
The 14–160 V DC input range covers all standardized onboard battery voltages from 24 to 110 V with a single version, simplifying PCB standardization in equipment manufactured for different markets. The potted construction withstands vibration and condensation in underfloor and roof-mounted installations.
For integration on PCBs in onboard equipment: intermediate converters in controllers, recorders and communication modules.
