Stroomadapter/omvormer MEAN WELL NID35-12, 35 W, ingang 20–53 V, uitgang 12 V, RoHS

MEAN WELL NID35-12 is a compact 35 W DC-DC converter designed to deliver a fixed 12 V output from a wide 20–53 V DC input range. Built for PCB mounting in a SIP open-frame package, the unit provides up to 2.9 A continuous output and includes a remote ON/OFF control for integration into automated systems. Its small footprint and low profile make it suitable for space-constrained industrial and embedded applications where a stable 12 V rail is required.

Advantages

The converter offers a high input voltage range and reliable 12 V regulation at up to 2.9 A, enabling use with diverse DC sources. Its SIP open-frame PCB-mount design minimizes board space and simplifies integration into custom power assemblies. The remote ON/OFF feature allows system-level control without additional external components. Compliance with RoHS ensures the unit meets common environmental and safety expectations for industrial electronics.

Suitable for

• Powering 12 V sensors, controllers and communication modules from wide-range DC supplies
• Embedded systems and compact industrial controllers with limited PCB area
• Automation equipment requiring remote enable/disable of the power rail
• Custom power distribution boards and retrofit designs

Key specifications

• Output voltage: fixed 12 V DC
• Output current: up to 2.9 A (35 W maximum)
• Input voltage range: 20–53 V DC
• Topology: non-isolated DC-DC converter (open-frame)
• Package type: SIP PCB-mount
• Control: remote ON/OFF function
• Mounting: through-hole PCB installation
• Environmental: RoHS compliant

How to use

Mount the converter onto the printed circuit board in the designated SIP through-hole footprint and solder the pins securely. Connect the DC input within the specified 20–53 V range to the input pins, and take the regulated 12 V output from the corresponding output pins, observing correct polarity. Use the remote ON/OFF pin to enable or disable the output from a microcontroller or external switch according to the system logic. Ensure adequate PCB copper area or thermal paths if the unit operates near its maximum load to assist heat dissipation.

Recommendations

For reliable long-term operation, provide sufficient ventilation and avoid operating at full load in confined enclosures. Keep input filtering and decoupling close to the converter input, and follow the manufacturer’s layout guidelines for grounding and thermal management to minimize noise and ensure stable regulation.
