SCWN03 & DCWN03 3W DC-DC Regulated Converters

MEAN WELL SCWN03 and DCWN03 3W DC-DC Regulated Converters are available in a DIP24 package with an industry-standard pinout and a 2:1 wide input range. These units offer a wide working temperature of -40°C to +90°C, efficiency of up to 87%, and a 3KV_DC I/P-O/P isolation voltage. Protections include short circuit (continuous), overload, and input undervoltage. Both series comply with EN55032 radiated Class A requirements without additional components. MEAN WELL SLC03 and DLC03 Regulated Converters are ideal for wireless networks, telecommunications, industrial control, analyzers, detectors, and distributed power architectures.
