Power adapter/inverter mean well RDDW08F-05, output 5 V, 8 W, 0.8 A

MEAN WELL RDDW08F-05 is a compact DC-DC railway dual-output converter configured to provide a single regulated 5 V output at up to 0.8 A (8 W). It accepts a wide input range of 9–36 VDC, features 1.5 kVDC input-to-output isolation, a DIP through-hole package, and a remote ON/OFF control. The module is RoHS-compliant and intended for low-power embedded systems, instrumentation, and small peripherals that require a stable 5 V supply.

Advantages

The RDDW08F-05 offers wide input-voltage compatibility (9–36 VDC) suitable for rail and vehicle power environments, galvanic isolation of 1.5 kVDC for safer system design, and a compact DIP through-hole form factor for easy PCB mounting. Remote ON/OFF allows system-level control and the unit’s 5 V, 0.8 A output provides a predictable, regulated supply for small electronics.

Suitable for

• Embedded control boards and microcontroller modules
• Instrumentation and measurement devices
• Small peripherals and sensors requiring 5 V
• Rail and vehicle electronics with 9–36 VDC sources

How to use

Mount the RDDW08F-05 in a suitable PCB footprint for DIP through-hole parts and connect the input to a 9–36 VDC source observing correct polarity. Connect the regulated 5 V output to the target load with appropriate decoupling. Use the remote ON/OFF pin according to the manufacturer’s pinout to enable or disable the output as part of system control. Ensure the ambient temperature and mounting allow adequate heat dissipation for continuous operation within rated limits.

Recommendations

For reliable operation, place adequate input and output capacitors near the module pins, observe the input voltage range, maintain required creepage and clearance for isolation, and follow MEAN WELL’s datasheet for pin assignments and thermal considerations. Avoid exceeding the 0.8 A rated output current and ensure proper ventilation when used in enclosed systems.
