Power adapter inverter MEAN WELL RDDW08G-12, 8 W, Input 18–75 V, Output 12 V

MEAN WELL RDDW08G-12 is a compact DC-DC converter designed to provide stable 12 V outputs from a wide DC input range. The module accepts 18–75 V input and delivers dual ±12 V outputs with a combined power rating of 8 W, making it suitable for applications that require galvanic isolation and low-power regulated supplies. The converter is built in a DIP through-hole package with 1.5 kV DC input-to-output isolation and includes a remote ON/OFF control for flexible system integration.

Advantages

The converter offers a wide input voltage window that supports varying supply conditions in industrial and vehicular environments. Dual ±12 V outputs provide both positive and negative rails from a single input source, simplifying power architecture for analog circuits and signal conditioning. High isolation between input and output improves safety and noise immunity, while the DIP through-hole format facilitates secure mounting and soldering on custom PCBs. Remote ON/OFF enables centralized power management.

Suitable for

• Railway and transportation electronics requiring isolated DC-DC conversion
• Industrial control and automation systems with mixed-signal circuitry
• Customer-specific PCBs where through-hole mounting is preferred
• Embedded equipment needing ±12 V rails for analog and sensor interfaces

Key specifications

• Input voltage range: 18–75 V DC
• Output configuration: dual outputs, ±12 V
• Output current: ±0.333 A per rail (total power 8 W)
• Isolation voltage: 1.5 kV DC between input and output
• Package type: DIP through-hole
• Remote control: ON/OFF remote enable/disable function
• Compliance: RoHS compliant

How to use

Connect the converter input to an appropriate 18–75 V DC source observing correct polarity and sufficient wiring gauge. Mount the DIP through-hole package securely on the PCB and solder all required pins. Connect the ±12 V outputs to the load, ensuring the combined load does not exceed the 8 W rating and that each rail remains within the ±0.333 A limit. Use the remote ON/OFF pin to control the converter from a system-level logic signal, following the manufacturer’s recommended voltage levels for enabling and disabling. Maintain the specified input and output grounding practices to preserve the isolation performance.

Recommendations

Allow adequate ventilation and avoid placing heat-sensitive components near the converter. Use input filtering and transient protection if the power source is subject to spikes or heavy noise. For reliable long-term operation, keep each output within its rated current, and verify isolation integrity during system-level safety tests.
