Power adapter MEAN WELL SPBW03G-15 3 W Input 18-75 V Output 15 V

The MEAN WELL SPBW03G-15 is a compact DC-DC converter in a SIP through-hole package designed for PCB mounting. It accepts a wide input range from 18 to 75 V DC and provides a regulated single output of 15 V DC at up to 0.2 A (3 W). The module is RoHS-compliant and intended for embedded power solutions where a small, reliable 15 V rail is required.

Advantages

The adapter offers a wide input voltage window (18–75 V) that accommodates various upstream supplies and transients. Its SIP through-hole package simplifies soldering and mechanical retention on printed circuit boards. With a fixed 15 V output and 3 W maximum power, the unit delivers stable voltage for low-power loads while meeting RoHS environmental standards.

Suitable for

• Embedded systems and control boards requiring a 15 V supply
• Industrial devices and instrumentation with 18–75 V input rails
• PCB-mounted power solutions where space is limited

Key specifications

• Brand: MEAN WELL
• Model / MPN: SPBW03G-15
• Input voltage: 18–75 V DC
• Output voltage: 15 V DC
• Output current: 0.2 A (max)

How to use

Solder the SIP through-hole pins into the designated PCB footprint, observing polarity and recommended PCB layout for power and thermal considerations. Apply an input DC voltage within 18–75 V to the input terminals and verify the output with a multimeter before connecting sensitive circuitry. Ensure the output load does not exceed 0.2 A and provide adequate clearance for any required cooling or neighboring components.

Recommendations

For reliable operation, operate the converter within the specified input range and rated load, follow the manufacturer's PCB layout guidance, and ensure proper solder joints. Avoid exceeding the 3 W output rating and verify that surrounding components allow sufficient ventilation and heat dissipation.
