Power adapter/inverter MEAN WELL DCWN06B-12 — 6 W, input 18–36 V, output 12 V

MEAN WELL DCWN06B-12 is a compact DC-DC regulated converter that converts an 18–36 V DC input to a regulated dual-output ±12 V supply with a total power rating of 6 W. Housed in a DIP through-hole package, it provides galvanic isolation between input and output and is intended for applications where a small, reliable isolated ±12 V rail is required. The unit is RoHS compliant and packaged for bulk use in manufacturing or large-scale installations.

Advantages

The device delivers a stable ±12 V dual output at low current levels with high input-to-output isolation up to 3000 VDC, helping to protect sensitive circuitry. Its through-hole DIP package simplifies PCB mounting and soldering for production and prototyping. The wide input range allows operation from common automotive and industrial 24 V systems, and the small footprint supports compact system designs.

Suitable for

• Low-power automotive electronics and vehicle control modules
• Industrial control systems and sensor interface circuits
• Embedded electronics requiring isolated ±12 V rails
• Manufacturing and production runs where bulk components are used

Key specifications

• Input voltage range: 18–36 V DC
• Output voltages: ±12 V DC
• Output current: ±0.25 A per rail (total power 6 W)
• Isolation voltage: 3000 V DC between input and output
• Package type: DIP through-hole
• Regulation: regulated dual output converter
• Compliance: RoHS compliant

How to use

Connect the DCWN06B-12 input terminals to a stable DC supply within the 18–36 V range, observing correct polarity and adequate wiring to minimize voltage drop. Mount the module on a PCB using standard through-hole soldering practices for DIP components. Provide appropriate input and output decoupling capacitors near the module as recommended by system design guidelines to improve transient response and noise performance. Ensure the output loads do not exceed ±0.25 A per rail and that total output power stays within the 6 W rating.

Usage recommendations

For reliable operation, maintain ambient temperature within the component’s specified operating range and ensure sufficient PCB copper area for heat dissipation. Use the converter with input sources that have limited start-up surges and include transient suppression if the supply environment is noisy. Verify isolation requirements in your system design and provide creepage and clearance distances on the PCB consistent with the isolation rating.
