For engineers designing industrial control panels, machinery, and automation systems, selecting a reliable, compact, and easy-to-install power supply is critical. The MORNSUN LI40-20BxxPU Series meets this need directly. This 40W DIN-rail mountable AC/DC converter series delivers high efficiency, exceptional noise immunity, and robust protection in a space-saving design, making it a cost-effective and green power solution for demanding industrial environments.

Core Features: Engineered for Industrial Resilience

The MORNSUN LI40-20BxxPU is built to provide stable power in a variety of harsh conditions, featuring key attributes that ensure long-term reliability and ease of integration.

• Universal Input & Dual-Use Terminal: It accepts a wide 85-264VAC input and also supports 120-370VDC input on the same terminals, offering exceptional flexibility for global mains or DC backup systems.
• High Isolation & Safety: With a high I/O isolation voltage of 4000VAC, it provides a strong safety barrier and protects sensitive equipment. Its design references key international safety standards including UL508, UL/EN/IEC62368, and UL61010.
• High Efficiency & Diagnostic Function: The series achieves efficiency of up to 90%, minimizing energy loss and heat generation. It also includes a practical DC OK signal to remotely monitor the output status for system diagnostics.
• Robust Protection & Wide Operating Range: Comprehensive protections include output short circuit, over-current, and over-voltage protection. It operates reliably across an ambient temperature range of -30°C to +70°C and at altitudes up to 5000 meters.
• Compact DIN-Rail Design: Designed for standard TS35/7.5 or TS35/15 DIN rail mounting, its compact form factor (100.00 x 36.50 x 90.00mm) saves valuable panel space and allows for quick, tool-free installation.

Complete Product Model Selection

The series offers four models to cover common voltage requirements for 40W applications. All models share the universal input, high isolation, and DIN-rail mounting.

Technical Specifications and Ideal Applications

The power supply provides stable output with low ripple & noise (80-200mVp-p depending on model) and features a calculated MTBF of ≥300,000 hours at 25°C. Its EMC performance meets CISPR32/EN55032 Class B for emissions and complies with the IEC/EN61000-4 series for immunity.
