Fuente de alimentación mean well RDDW20F-15 — 20 W, 15 V, 0,666 A, RoHS

Mean Well RDDW20F-15 is a compact DC-DC railway dual output converter designed for embedded and small electronic systems. It accepts a wide input range of 9–36 VDC and provides dual outputs of ±15 VDC at ±0.666 A with 1.5 kVDC input/output isolation. The module is supplied in a DIP through-hole package with remote ON/OFF control and is RoHS compliant. Its small size (depth 50.8 mm) and light weight (35 g) make it suitable for space-constrained applications and OEM integration.

Advantages

The converter delivers regulated dual outputs with galvanic isolation to protect sensitive circuitry and reduce interference. Its wide input voltage range permits use with varied DC sources in railway and industrial environments. The DIP through-hole package simplifies PCB mounting for prototypes and production, while the remote ON/OFF feature enables external control. Low weight and compact dimensions support integration into compact equipment and embedded designs.

Suitable for

• Embedded systems and small industrial controllers
• Railway electronics and vehicle-mounted equipment
• OEM power supplies and electronic modules
• Prototyping and PCB-mounted applications
• Repair and production runs (bulk supply)

How to use

Mount the RDDW20F-15 into the PCB using the DIP through-hole pins and ensure proper soldering for reliable electrical and mechanical connection. Connect a DC input source within 9–36 VDC to the input terminals, observing correct polarity. Use the ±15 V outputs to power downstream circuitry, keeping combined output currents within the specified ±0.666 A per rail and total power within 20 W. Implement appropriate input and output filtering and decoupling on the PCB according to application needs. Use the remote ON/OFF control per the manufacturer’s connection diagram to enable or disable the converter without removing power.

Recommendations

Provide adequate spacing and ventilation around the module and follow recommended PCB layout and grounding practices to maintain isolation performance and minimize thermal buildup. Verify input voltage limits and derate load if operating near maximum temperature or at the edge of input range. For production, handle bulk-supplied units with ESD precautions and confirm soldering profile compatibility with the through-hole package.
