Power adapter/inverter MEAN WELL NID65-24 — 65 W, 24 V output, 30–53 V input, RoHS, compact 26×50.8×11 mm

MEAN WELL NID65-24 is a compact DC-DC converter delivering 65 W of power with a regulated 24 V output. Designed as a non-isolated open-frame PCB-mount module in a SIP package, it accepts a wide input range of 30–53 V DC and provides up to 2.7 A output current. The unit includes a remote ON/OFF control and is sized for installations with limited board space, measuring 26 × 50.8 × 11 mm. It complies with RoHS requirements and is intended for use in industrial control, embedded systems and other applications that require reliable DC power conversion on printed circuit boards.

Advantages

The converter offers a high power density in a very small footprint, enabling power conversion where space is restricted. The wide 30–53 V input range accommodates typical vehicle, telecom and industrial supply voltages, while the regulated 24 V output provides stable power for downstream electronics. Its PCB-mount SIP form factor simplifies integration into board-level designs, and the remote ON/OFF feature allows external control for power sequencing and energy saving. Compliance with RoHS supports environmentally conscious designs.

Suitable for

• Industrial control systems and PLC modules
• Embedded and single-board computer power rails
• Telecom equipment and network devices
• Battery-backed systems and vehicular electronics with 30–53 V buses

How to use

Mount the module directly on the printed circuit board following the recommended footprint and soldering guidelines from the manufacturer. Connect the input supply within the 30–53 V DC range to the designated input pins, and take the 24 V regulated output from the output pins, observing polarity. Use the remote ON/OFF control to enable or disable the output during power sequencing; ensure the control signal conforms to the converter's specified logic levels. Provide adequate thermal management on the PCB for continuous operation at full load, and design input/output filtering and transient protection as needed for the application.

Recommendations

For reliable long-term operation, maintain input voltage within the specified range and avoid prolonged operation at maximum ambient temperature without sufficient PCB-level cooling. Apply proper decoupling and transient suppression on input and output lines, and follow the manufacturer’s layout and grounding guidance to minimize EMI and ensure stable regulation.
