Power adapter/inverter MEAN WELL RDDW08F-12, 8 W, 12 V, 0.333 A, RoHS

MEAN WELL RDDW08F-12 is an 8 W DC-DC railway dual output converter supplied in a DIP through-hole package. It accepts a wide input range of 9–36 VDC and provides regulated dual outputs of ±12 VDC with nominal output currents of ±0.333 A. The unit includes 1.5 kVDC input-to-output isolation, a remote ON/OFF control pin, and is designed to meet RoHS requirements. It is intended for compact, low-power electronic systems where a small, isolated dual supply is required.

Advantages

The converter offers a compact through-hole form factor suitable for PCB mounting, wide input voltage compatibility for varied power sources, and galvanic isolation between input and outputs up to 1.5 kVDC. Dual ±12 V rails provide balanced supplies for analog and digital circuits, while the remote ON/OFF feature enables system-level control. The regulated outputs and RoHS compliance make it appropriate for equipment with environmental and electrical stability requirements.

Suitable for

• Embedded controllers and small industrial electronics that require isolated dual supplies
• Sensors and signal-conditioning modules needing ±12 V rails
• LED modules and low-power actuator circuits with tight space constraints
• Railway and transportation electronics with wide input voltage sources

How to use

Mount the MEAN WELL RDDW08F-12 into the PCB using the DIP through-hole leads and ensure correct orientation according to the manufacturer's pinout. Provide a suitable input voltage between 9 and 36 VDC and connect load circuits to the ±12 V outputs within the specified current limits (±0.333 A per rail). Use the remote ON/OFF pin to enable or disable the outputs as required by the system. Observe recommended PCB layout and decoupling practices to maintain stable regulation and minimize noise.

Recommendations

Operate the converter within its input and output ratings and provide adequate clearance and thermal handling on the PCB. For reliable isolation performance, follow creepage and clearance guidelines and avoid exposing the device to voltages beyond its 1.5 kVDC isolation rating. When used in railway or transportation applications, verify compatibility with system-level transient protection and filtering requirements.
