MEAN WELL DPBW03G-15 DC-DC-muunnin, 3W, 15V 200mA, 9-18V tulo, DIP24, eristetty

Embedded systems engineers often face the challenge of deriving a stable 15V rail from a fluctuating 9–18V DC bus. The MEAN WELL DPBW03G-15 solves this with a compact, isolated 3W DC-DC converter that fits directly onto a DIP24 PCB footprint. Its 2:1 wide input range accommodates battery-powered or industrial intermediate bus voltages, while the 1500VDC isolation protects sensitive logic from ground loops and transients.
