Fonte de alimentação/inversor MEAN WELL RDDW08F-15, saída 15 V, 8 W, 0,265 A

MEAN WELL RDDW08F-15 is a compact DC-DC railway dual output converter delivering ±15 VDC at ±0.265 A with an 8 W total output. Designed for installation in through-hole PCB assemblies, this unit accepts a 9–36 VDC input and provides galvanic isolation between input and outputs, supporting applications where a stable, isolated low-voltage supply is required. The converter includes a Remote ON/OFF control and meets RoHS environmental requirements.

Advantages

The module offers dual symmetric outputs that eliminate the need for additional bipolar power arrangements, while the 1.5 kVDC input-to-output isolation enhances safety and noise immunity in signal-sensitive environments. Its DIP through-hole package facilitates reliable PCB mounting, and the wide input range allows use with varied onboard supplies. The Remote ON/OFF feature enables straightforward power control from system logic.

Suitable for

• Railway and transportation electronics requiring isolated bipolar supplies
• Embedded systems and control modules with limited board space
• Signal converters, sensor interfaces and analog circuitry needing ±15 V rails
• LED drivers and low-power modules that need stable isolated DC power

Key specifications

• Input voltage range: 9–36 VDC
• Output voltages: ±15 VDC
• Output current: ±0.265 A per rail
• Total output power: 8 W
• Isolation voltage (input-to-output): 1.5 kVDC
• Package type: DIP through-hole
• Control: Remote ON/OFF pin
• Compliance: RoHS

How to use

Mount the converter in a compatible through-hole footprint on the PCB, observing correct polarity for input and output connections. Apply an input voltage within the 9–36 VDC range and use the Remote ON/OFF pin to enable or disable the outputs according to your system logic levels. Provide adequate decoupling and follow standard PCB layout practices for isolated converters, maintaining creepage and clearance distances consistent with the isolation rating.

Recommendations

For reliable operation, avoid exceeding the rated output current and operate within the specified input voltage range. Ensure thermal management through appropriate board layout or spacing from heat-sensitive components. When integrating into safety-critical or rail applications, validate the converter in the final system environment and follow relevant standards for isolation and electromagnetic compatibility.
