Power adapter/inverter Mean Well NID65-12, 65W, 12V output, input 20–53V, RoHS

Mean Well NID65-12 is a compact DC-DC converter providing regulated 12 V output up to 65 W from a wide 20–53 V DC input range. Its SIP open-frame PCB-mount form factor and small footprint (26 × 50.8 × 11 mm) make it suitable for space-constrained designs where a stable 12 V supply is required. The converter is a non-isolated step-down solution with remote ON/OFF control and RoHS compliance for applications in telecommunications, industrial control and embedded systems.

Advantages

The NID65-12 delivers up to 4.9 A at 12 V with efficient DC-DC conversion across a broad input voltage window, reducing the need for multiple power rails. Its SIP package and open-frame design enable direct PCB mounting and efficient thermal conduction. Remote ON/OFF functionality allows system-level power management, while RoHS compliance ensures adherence to environmental material standards. The device's compact dimensions support integration into densely populated assemblies.

Suitable for

• Telecommunications equipment and network devices
• Industrial control modules and automation systems
• Embedded systems and single-board computers
• Point-of-sale terminals and compact appliances
• Battery-fed or vehicle DC systems using 20–53 V inputs

How to use

Install the converter directly onto a PCB using the SIP pins, following the manufacturer's recommended footprint and soldering guidelines. Connect the DC input within the specified 20–53 V range and route the 12 V output to the load with appropriate wiring and decoupling. Use the remote ON/OFF pin to enable or disable the output from a system controller or logic signal, observing the required control voltage levels. Ensure adequate PCB copper area or thermal vias for heat dissipation when operating near the maximum load.

Recommendations

For reliable operation, provide adequate input filtering and transient protection on the supply line and avoid operating continuously at maximum rated output without thermal management. Place output capacitors close to the converter output pins and follow layout guidelines to minimize noise. When used in vehicle or battery-fed systems, verify input surge and transient conditions and add protection as needed.
