3 WATT Regulated Dual Output DC to DC Converter with 8:1 Ultra-Wide Input
DCWN03W8
The MEAN WELL DCWN03W8 series are 3W isolated, dual output regulated DC-DC converters in a DIP24 package. They use standard pinouts and offer a high level of efficiency. Designed to operate in harsh environments, they have a wide operating temperature range from –40°C to +95°C (refer to derating curve in data sheet) and provide 3kVDC isolation between input and output.
These modules meet BS EN/EN55032 Class B (radiated) standards without needing extra components. They include continuous short-circuit protection and boast an ultra-wide input range of 9–75V (8:1).
Output options include:
- ±5V, ±12V, ±15V
Ideal for industrial control, telecom systems, distributed power architectures, and similar applications.
