Voeding/omvormer Mean Well SPB09C-24, 9 W, ingang 36–75 V, uitgang 24 V, RoHS, diepte 24 mm

Mean Well SPB09C-24 is a compact DC-DC regulated converter designed for PCB mounting where a stable 24 V supply is required from a higher-voltage DC source. The module accepts a wide input range of 36–75 V DC and delivers a single fixed 24 V output rated at 0.375 A (9 W). Packaged in a SIP through-hole form with just 24 mm depth and very low weight, it is suitable for space-constrained industrial and embedded systems that need reliable isolated DC–DC conversion and an ON/OFF control option.

Advantages

The converter provides a regulated 24 V output with a wide input window, enabling use with various battery and industrial supply voltages. Its small SIP through-hole package and 24 mm depth facilitate integration on crowded PCBs. The unit includes a remote ON/OFF function for system-level power management and complies with RoHS requirements for reduced hazardous substances. Low-power consumption and stable output make it suitable for continuous operation in low-power applications.

Suitable for

• Embedded control boards and industrial automation modules
• Telecom and networking equipment with higher DC supply rails
• Battery-powered systems and vehicles that provide 36–75 V inputs
• Signal conditioning and sensor power where a regulated 24 V is required

How to use

Mount the SIP through-hole module on the PCB following the manufacturer’s recommended footprint and ensure correct polarity of input and output connections. Provide the specified input voltage within 36–75 V DC and verify the load does not exceed 0.375 A at 24 V. Use the remote ON/OFF pin according to the control logic levels specified in the technical datasheet to enable or disable output as needed. Ensure adequate spacing and thermal considerations on the PCB for continuous operation at rated power.

Recommendations

Use short, low-impedance traces for input and output connections and place input decoupling capacitors close to the module to minimize noise. When integrating into systems with battery or vehicle supplies, add transient protection such as TVS diodes or fuses on the input to protect against surges. Verify thermal performance under your specific load and ambient conditions, and consider forced airflow or additional heat dissipation if operating near maximum load.
