Power adapter/inverter Mean Well SPB09B-05, 9 W, input 18–36 V, output 5 V, RoHS, 24 mm depth, 5 g

Mean Well SPB09B-05 is a compact DC‑DC regulated converter in a SIP through‑hole package, providing a single 5 Vdc output at up to 1.6 A from an 18–36 Vdc input. The module is designed for board‑level power conversion in low‑power electronics and embedded systems, offering a small 24 mm depth, lightweight 5 g construction, RoHS compliance and a remote ON/OFF control pin.

Advantages

The SPB09B-05 delivers stable 5 V output with tight regulation and efficient conversion in a small SIP form factor suitable for PCB mounting. Its wide input range (18–36 Vdc) accommodates varying supply voltages, while the remote ON/OFF feature enables convenient system control. The unit is RoHS compliant and designed for bulk OEM installation with a compact footprint and low weight.

Suitable for

• Embedded systems and microcontroller boards
• Board‑level power rails in industrial and networking equipment
• Space‑constrained applications and compact enclosures
• OEM production and high‑volume assembly
