Product information

Description

The MEAN WELL DCWN03C-12 electric converter 3 W 36-72 V 125 mA is a compact DC-DC converter designed to deliver a regulated output current from a wide DC input range. Intended for installations where space is limited, this converter accepts 36–72 V DC and supplies a stable 125 mA output with a rated power of 3 watts. The small form factor and straightforward electrical characteristics make it suitable for embedded systems, lighting drivers, and industrial control circuits that require a low-power, constant-current source.

Advantages

This converter offers a wide input voltage range that accommodates varying supply conditions and simplifies system design. Its low power rating and constant-current output provide predictable behavior for LED loads and other current-driven devices. The compact size reduces installation space and allows placement in constrained enclosures. The design emphasizes electrical stability and ease of integration into existing low-voltage DC systems.

Suitable for

  • Low-power LED modules and indicator lighting requiring a constant current source
  • Small embedded and IoT devices with a 36–72 V supply rail
  • Industrial control circuits and sensor interfaces needing regulated current
  • Battery-powered or vehicle systems operating within the specified input range

Key specifications

  • Input voltage range: 36–72 V DC
  • Output: constant current 125 mA
  • Rated output power: 3 W
  • Form factor: compact, suitable for constrained installations
  • Intended operation: low-power DC-DC conversion for current-driven loads

How to use

Connect the converter to a stable DC supply within the 36–72 V range, observing correct polarity. Wire the load to the converter’s output so that the device provides the specified 125 mA constant current. Ensure that the connected load and wiring do not exceed the rated 3 W output power. Mount the unit in a location with adequate ventilation and secure electrical connections to prevent loosening under vibration or thermal cycling.

Usage recommendations

Verify compatibility of the load with a constant-current supply and ensure the power dissipation of the load and wiring remains within safe limits. Provide sufficient clearance for heat dissipation, avoid exposure to moisture and corrosive environments, and include appropriate fusing on the input side to protect against overcurrent conditions.
