MEAN WELL DPU01L-12 1W DC-DC Converter Module 12V Input 12V Output SIP

The DPU01L-12 stands apart from typical DC-DC converters by combining a remarkably compact SIP package with a wide -40 to +85 °C operating range, making it a reliable choice for space-constrained industrial and telecom applications. This 1 W isolated module accepts a nominal 12 VDC input and delivers a regulated 12 VDC output with continuous short-circuit protection and auto-recovery, ensuring stable performance even under fault conditions.

Highlights

• Ultra-compact SIP package for through-hole mounting
• Wide operating temperature range: -40 to +85 °C
• Continuous short-circuit protection with auto-recovery
• 1000 VDC isolation between input and output
• High efficiency up to 70%
• Low ripple & noise: 100 mVp-p maximum
• MTBF over 3.5 million hours for long-term reliability

In daily use

Engineers and system integrators will appreciate the DPU01L-12 for its straightforward integration into PCB designs. The single-in-line package simplifies board layout, while the tight line and load regulation (±1.2% and ±15% respectively) ensure consistent output under varying input and load conditions. The module operates across a 10.8 to 13.2 VDC input range, making it suitable for battery-powered or loosely regulated 12 V systems. Its 20 to 95% RH non-condensing humidity tolerance further extends its versatility in harsh environments.
