Power adapter/inverter MEAN WELL RSDW10H-03, 10 W, Input 43–160 V, RoHS, 16 g

MEAN WELL RSDW10H-03 is a compact DC-DC railway single output converter that delivers 3.3 VDC at up to 2.5 A from a wide input range of 43–160 VDC. The module provides 1.5 kVDC input-to-output isolation, remote ON/OFF control and is supplied in a DIP through-hole package. With a power rating of 10 W and a lightweight design (16 g), it is intended for low-power industrial and electronic applications requiring a small, robust DC/DC power solution.

Advantages

The RSDW10H-03 offers a wide input voltage range suitable for railway and industrial environments, reliable 1.5 kVDC isolation between input and output, and a compact DIP through-hole form factor for straightforward PCB mounting. Remote ON/OFF functionality enables external control of the module, and RoHS compliance ensures adherence to standard environmental requirements. The low weight and 10 W power rating make it convenient for space- and weight-constrained designs.

Suitable for

• Low-power railway electronic modules
• Industrial control and monitoring circuits
• Embedded systems requiring isolated 3.3 V supply
• PCB-mounted power solutions in compact devices

How to use

Mount the DIP through-hole module on the PCB according to the manufacturer’s recommended footprint and pin orientation. Connect a suitable input rail within the 43–160 VDC range to the input pins, and take the regulated 3.3 VDC output from the output pins, observing correct polarity. Use the remote ON/OFF pin for external enable/disable control as required by the application. Respect the device’s 10 W power limit and provide adequate thermal management and clearances for the 1.5 kVDC isolation rating.

Recommendations

For reliable operation, ensure input voltage stays within 43–160 VDC, do not exceed the 2.5 A output current, and follow PCB layout guidelines for isolation and thermal dissipation as provided in the MEAN WELL datasheet. Verify RoHS compliance requirements in your application and use appropriate surge and transient protection in railway or industrial environments.
