Power adapter/inverter Mean Well SPA01A-05, output 5 V DC, 0.2 A, 1 W, RoHS

Mean Well SPA01A-05 is a compact DC-DC regulated single-output converter that delivers 5 V DC at 0.2 A (1 W) in a SIP package. The module provides 1500 VDC input-to-output isolation and is RoHS compliant, making it suitable for low-power embedded electronics, signal devices and small sensors where space and electrical isolation are required.

Advantages

The SPA01A-05 offers regulated 5 V output at up to 0.2 A with built-in 1500 VDC isolation between input and output, a very small and lightweight SIP form factor (approximately 3 g), and compliance with RoHS standards. Its regulated output and isolation simplify integration into circuits that need stable low-voltage power and protection between different voltage domains.

Suitable for

• Embedded electronics and microcontroller modules
• Signal conditioning and communication modules
• Small sensors and measurement devices
• Space-constrained applications requiring electrical isolation

How to use

Install the SPA01A-05 on a PCB using the SIP pins according to the manufacturer’s recommended footprint and observe polarity when connecting input and output. Provide input voltage within the converter’s specified range (refer to the official datasheet for input limits), and route grounds and signals to maintain the rated isolation. Use appropriate decoupling and ensure the module’s output load does not exceed 0.2 A to prevent overheating or regulation loss.

Recommendations

The converter is intended for low-power applications; consult the Mean Well datasheet for detailed input voltage range, thermal considerations, and recommended PCB layout. For applications requiring higher current or power, select a module with appropriate ratings. Maintain clearance and creepage distances on the PCB to preserve the 1500 VDC isolation.
