Key parameters: 100 W output power, 12 V output voltage, input range 20–53 V, RoHS compliance. Compact and lightweight (depth 50.8 mm, height 12 mm, weight 35 g). Suited for industrial and embedded power supplies, LED drivers, and mobile equipment.

## Long description

MEAN WELL NID100-12 is a compact DC‑DC non‑isolated converter that converts a wide 20–53 V input range to a regulated 12 V DC output with up to 100 W power. Designed as an open‑frame, SIP‑style PCB mount module, it provides a high current 12 V rail (7.5 A) in a shallow package (depth 50.8 mm, height 12 mm) and weighs approximately 35 g. The module includes a Remote ON/OFF function and complies with RoHS requirements, making it suitable for embedded power designs, LED drivers and mobile equipment where space and weight are constrained.
Advantages
The NID100-12 offers a wide input voltage window (20–53 V) that accommodates varying battery or bus voltages and enables use across different vehicle and industrial systems. Its open‑frame SIP package allows direct PCB mounting to save enclosure space, while the non‑isolated topology provides high conversion efficiency for heat‑sensitive applications. Remote ON/OFF control adds convenient system integration and power sequencing options. The small footprint and low weight support compact and mobile applications without compromising a stable 12 V supply.
Suitable for
 Embedded systems and single‑board computers requiring a stable 12 V supply
 LED drivers and lighting modules with 12 V input
 Mobile and vehicular equipment with 20–53 V battery or bus voltages
 Industrial control modules and instrumentation with PCB-mounted power conversion

How to use
Mount the module directly onto the PCB using the SIP pins, ensuring proper soldering and mechanical support. Connect the input terminals to a 20–53 V DC source, observing correct polarity and adequate decoupling on the input to minimize noise. Connect the 12 V output to the load, making sure the combined current demand does not exceed 7.5 A and that wiring and connectors are rated for the current. Use the Remote ON/OFF pin to control power sequencing according to the system design; follow manufacturer guidance for the required control signal levels. Provide adequate thermal management and ventilation in the final assembly to maintain reliable operation under full load.
Usage recommendations
To ensure reliable performance, place input and output decoupling capacitors close to the module pins, avoid running high‑current traces near sensitive signal lines, and verify thermal conditions in the target enclosure. For mobile or vehicular installations, confirm the input source can tolerate transients within the 20–53 V range. When designing for continuous operation near the 100 W limit, implement forced airflow or additional heatsinking as needed.
