Product information

Description

MEAN WELL RSDW20H-05 is a DC-DC railway single output converter providing a regulated 5 VDC output at up to 4 A from a wide 43–160 VDC input range. The module features 3 kVDC input-to-output isolation, a DIP through-hole package with a compact 50.8 mm depth and a lightweight 35 g construction. It includes a remote ON/OFF control and is RoHS compliant, making it suitable for industrial and embedded systems that require a small, reliable 5 V supply.

Advantages

The RSDW20H-05 offers a wide input range compatible with railway and industrial DC supplies, high isolation between input and output for enhanced safety, and a compact DIP through-hole form factor for straightforward PCB mounting. Its remote ON/OFF function allows external control of the output, and the low weight and small depth facilitate use in space-constrained installations. RoHS compliance ensures it meets common environmental standards.

Suitable for

  • Embedded control systems in rolling stock and railway equipment
  • Industrial automation modules requiring a stable 5 V rail
  • Communication and signalling devices powered from high-voltage DC busses
  • PCB-mounted power supplies in compact electronic assemblies

Key specifications

  • Output: 5 VDC, 4 A (20 W)
  • Input voltage range: 43–160 VDC
  • Isolation: 3 kVDC input-to-output
  • Package: DIP through-hole
  • Depth: 50.8 mm
  • Weight: 35 g
  • Remote ON/OFF: yes
  • Compliance: RoHS

How to use

Mount the RSDW20H-05 on a PCB using the DIP through-hole pins and ensure proper soldering for mechanical stability and electrical contact. Connect the high-voltage DC input within the specified 43–160 VDC range to the designated input pins, and take the regulated 5 VDC output from the output pins. Use the remote ON/OFF pin to enable or disable the output from external logic or a switch; follow the manufacturer’s pinout and control logic levels. Observe correct polarity and grounding practices and provide adequate clearance and creepage distances on the PCB for the 3 kV isolation rating.

Usage recommendations

Ensure adequate board-level creepage and clearance for high-voltage input lines, add input filtering if the system environment is noisy, and verify thermal conditions in the final enclosure to keep the converter within its rated operating temperature. For batch installations, follow MEAN WELL’s datasheet for pinout, mechanical dimensions, and recommended footprint.
