Fonte de alimentação/conversor MEAN WELL RDDW08G-15, 8 W, entrada 18–75 V, saída 15 V

MEAN WELL RDDW08G-15 is an 8 W DC-DC converter designed for compact, reliable conversion of wide-range DC inputs to isolated ±15 V outputs. The module accepts an input voltage between 18 and 75 V and delivers dual outputs of ±15 V with rated currents suitable for low-power industrial electronics, embedded systems and LED driver supplies. Housed in a DIP through-hole package with remote ON/OFF capability and 1.5 kVDC input-to-output isolation, this converter is intended for applications that require galvanic isolation and a small footprint.

Advantages

The converter provides a wide input range that accommodates common industrial and vehicle power rails, ensuring compatibility with various DC sources. Its dual ±15 V outputs offer symmetrical rails for analog and mixed-signal circuits, while the rated power and current make it appropriate for low-power control electronics. The 1.5 kVDC isolation improves safety and noise immunity between input and output circuits. The DIP through-hole package facilitates mechanical installation and soldering in PCB designs, and the remote ON/OFF feature adds flexible power control.

How to use

Connect the input terminals to a stable DC source within the specified 18–75 V range, observing correct polarity. Mount the DIP package into the PCB footprint compatible with through-hole soldering and ensure proper clearance for thermal dissipation. Use the remote ON/OFF control pin according to the manufacturer’s logic levels to enable or disable the outputs. Verify output voltages under load conditions close to expected operating currents and apply appropriate decoupling and filtering on the output rails for sensitive analog circuitry.

Recommendations

Operate the converter within the specified input voltage and output current limits to maintain reliability. Provide adequate board-level heat dissipation and avoid exposing the module to excessive ambient temperatures. When used in noise-sensitive applications, add local filtering and follow recommended PCB layout practices to minimize coupling between input and output circuits.
