Fonte de alimentação MEAN WELL SPB09A-24, 9 W, 24 V, 0,375 A, RoHS

MEAN WELL SPB09A-24 is a compact DC-DC regulated converter designed for PCB mounting in a SIP through-hole package. It accepts a wide input range and delivers a stable 24 Vdc single output with a maximum current of 0.375 A, making it suitable for low-power electronic systems and industrial control modules. The module includes remote ON/OFF control and is RoHS compliant. Its small depth (24 mm) and light weight support space-constrained designs and tight integration into assemblies.

Advantages

The converter offers regulated output performance across a wide input voltage range with low power dissipation, enabling reliable operation for sensitive electronics. Its SIP through-hole form factor simplifies PCB installation and mechanical retention. Remote ON/OFF functionality provides convenient power control without additional external switching circuitry. Compliance with RoHS supports environmentally conscious applications and manufacturing processes.

How to use

Install the module directly onto the printed circuit board using its through-hole pins, ensuring correct polarity and secure solder joints. Provide input voltage within the specified 9–18 Vdc range and observe the maximum output current rating to avoid overload. Use the remote ON/OFF pin according to the manufacturer's control logic to enable or disable the output without interrupting the input supply. Allow for adequate spacing and thermal paths on the PCB to dissipate heat during continuous operation.

Recommendations

For stable long-term performance, mount the converter on a PCB with sufficient copper area for heat spreading, add input and output decoupling capacitors close to the pins, and avoid operating continuously at the maximum output current in high ambient temperatures. Verify compatibility of the 24 V output with downstream circuits and include appropriate fusing or current limiting as required by the final application.
