Product information

Description

MEAN WELL RSDW20F-03 is a compact DC-DC railway single output converter designed for industrial and transportation applications. It accepts a wide input range of 9–36 VDC and provides a regulated 3.3 VDC output at up to 5.5 A, delivering a nominal 20 W output in a DIP through-hole package with remote ON/OFF control and 1.5 kVDC input/output isolation.

Advantages

The converter combines a small form factor (50.8 mm depth, 35 g weight) with RoHS compliance, isolation suitable for railway and industrial environments, and remote ON/OFF functionality for system integration. Its single 3.3 V output and 20 W power rating make it suitable for low-voltage, space-constrained applications requiring stable DC supply and electrical isolation.

Suitable for

  • Railway and onboard electronics
  • Industrial control and automation modules
  • Embedded systems and OEM assemblies with space constraints
  • Volume production and PCB through-hole mounting

Key specifications

  • Input voltage: 9–36 VDC
  • Output voltage: 3.3 VDC
  • Output current: up to 5.5 A
  • Output power: 20 W
  • Isolation: 1.5 kVDC I/O
  • Package: DIP through-hole
  • Depth: 50.8 mm
  • Weight: 35 g
  • Remote ON/OFF: yes
  • Compliance: RoHS

How to use

Mount the RSDW20F-03 in a PCB through-hole footprint matching its DIP package. Connect the input to a 9–36 VDC source observing polarity and grounding practices. Route the 3.3 VDC output to the load, ensuring the total current does not exceed 5.5 A and the power dissipation limits of the system. Use the remote ON/OFF pins to control the converter according to the manufacturer’s logic levels. Maintain the specified isolation clearance and follow typical railway/industrial wiring standards.

Usage recommendations

Ensure adequate ventilation or thermal management when operating near the 20 W limit, verify system grounding and isolation requirements for railway applications, and follow MEAN WELL documentation for layout, input filtering, and remote ON/OFF wiring to ensure reliable long-term operation.
