Fonte de alimentação/transformador MEAN WELL DKMW20F-12, 20 W, 12 V, 0,83 A, RoHS

MEAN WELL DKMW20F-12 is a compact PCB-mounted DC-DC converter designed to provide a low-power dual ±12 V output from a wide input range. The module accepts 9–36 Vdc input and delivers dual outputs of ±12 V at ±0.83 A each, with an overall power rating of 20 W. Its 1" x 1" DIP through-hole package and 18 g weight make it suitable for embedded systems and space‑constrained designs that require a reliable isolated or non-isolated 12 V rail. The module includes Remote ON/OFF control and is manufactured to meet RoHS environmental requirements.

Advantages

The converter’s ultra-compact 1" x 1" size and DIP through-hole format enable easy PCB mounting and high-density assembly. A wide 9–36 Vdc input range supports operation from various supply sources, including battery and vehicle systems. Dual ±12 V outputs provide symmetrical rails for analog and mixed-signal applications while keeping power consumption and weight low. Remote ON/OFF functionality allows system-level control without additional external circuitry.

Suitable for

• Embedded electronics and microcontroller systems requiring ±12 V rails
• Small DC-powered devices and instrumentation
• Volume installations and compact power distribution boards
• Battery- or vehicle-powered equipment with varying input voltages
• PCB designs where through-hole mounting and thermal handling are required

How to use

Install the module into the PCB using the DIP through-hole pins and ensure proper soldering for mechanical and thermal stability. Connect a DC source within the 9–36 Vdc range to the input terminals, observing polarity. Use the Remote ON/OFF pin to enable or disable outputs from system logic, following the manufacturer’s recommended control levels. Route adequate copper and consider thermal relief or airflow if operating near maximum load to maintain rated performance.

Recommendations

For stable operation, keep input decoupling and recommended layout practices near the converter pins, provide short and wide traces for power paths, and avoid placing sensitive analog circuitry directly adjacent to the module. Verify heat dissipation and derate output current if ambient temperature or enclosure constraints reduce cooling efficiency.
