Voeding/spanningsomvormer Mean Well SPB09B-24, 9 W, ingang 18-36 V, uitgang 24 V, RoHS

Mean Well SPB09B-24 is a compact DC-DC regulated converter delivering 9 W of power with a fixed 24 V output. The module accepts a wide input range of 18–36 Vdc and provides a single 24 Vdc output rated for 0.375 A. Designed as a SIP through-hole PCB-mount device with a shallow 24 mm depth and lightweight construction, this RoHS-compliant adapter/inverter is intended for distributed power systems, control electronics and other low-power embedded applications where a reliable DC-to-DC step-up or isolation is required.

Advantages

The converter offers a compact footprint and low profile suitable for dense PCB layouts, combined with regulated output for stable voltage delivery under variable input conditions. Its SIP through-hole package simplifies mechanical mounting and soldering on printed circuit boards, while the wide input range enables compatibility with various battery and intermediate bus voltages. A remote ON/OFF function allows easy system-level control without additional external components.

Suitable for

• Distributed power modules and intermediate bus systems
• Control electronics and PLC peripheral circuits
• Signal conditioning and low-power instrumentation
• Battery-powered equipment and vehicle electronics with 18–36 V rails

How to use

Mount the SIP through-hole converter on the PCB following the manufacturer’s recommended land pattern and soldering guidelines. Connect the input supply within the specified 18–36 Vdc range and verify correct polarity before powering. Use the remote ON/OFF pin to enable or disable the output from system logic if required; observe the recommended logic levels in the device documentation. Allow appropriate clearance for thermal dissipation and avoid exposing the module to voltages or currents beyond its rated limits.

Recommendations

For stable operation, include input filtering and transient protection at the supply source, and place output decoupling capacitors close to the load. Ensure the printed circuit board provides adequate copper area for heat spreading, and verify that the ambient temperature and enclosure ventilation meet the thermal requirements for continuous 9 W operation.
