1. Core Technical Specifications: Power, Isolation, and Reliability

The MP-U36S05-PS 36W Ultra-Compact AC-DC Bare Board Power Supply is engineered to meet industrial-grade performance benchmarks, with specifications tailored to diverse global and environmental requirements:

2. Key Features: Industrial-Grade Design for Demanding Environments

The MP-U36S05-PS 36W Ultra-Compact AC-DC Bare Board Power Supply integrates features that solve common pain points in industrial power design:

2.1 Bare Board Layout with Fanless Cooling

The bare board design eliminates moving parts (e.g., fans) that are prone to failure due to dust, vibration, or wear—critical for industrial environments with high particulate levels (e.g., manufacturing plants). Optimized copper traces on the board enhance heat dissipation, while compatibility with external heatsinks (sold separately) allows for customization in high-temperature applications (e.g., +60°C enclosures). ShwayPCB backs this design with a ≥3-year warranty, validated through accelerated life testing (ALT) under industrial operating conditions.

2.2 Comprehensive Protection Mechanisms

To ensure system safety and uptime, the power supply includes multi-layer protection against power anomalies:

2.3 Series Compatibility with MP-U36SXX-PS

The MP-U36S05-PS is part of the MP-U36SXX-PS Series 36W AC-DC Power Supplies, which offers multiple output voltages (5V, 12V, 24V, 36V, 48V) while maintaining the same form factor, input range, and isolation rating. This standardization allows engineers to use a single power supply platform across diverse projects—for example, pairing the 5V MP-U36S05-PS with sensors and the 24V MP-U36S24-PS with industrial motors—reducing inventory complexity and design time.

3. Application Scenarios: Where the MP-U36S05-PS Adds Value

The MP-U36S05-PS 36W Ultra-Compact AC-DC Bare Board Power Supply is optimized for industrial and commercial use cases that require compact, reliable power:

3.1 Industrial Automation Systems

In programmable logic controllers (PLCs), human-machine interfaces (HMIs), and sensor networks, the power supply delivers stable 5V power to low-voltage components. Its 3000VAC isolation protects PLC circuits from high-voltage transients in factory grids, while its -25°C to +60°C operating range ensures performance in temperature-fluctuating manufacturing environments.

3.2 Communication Infrastructure

IoT gateways, 4G/5G modems, and Ethernet switches rely on consistent 5V power for their internal electronics. The 85-264VAC input range works with backup generators (common in remote communication towers), and 88% efficiency reduces power consumption—critical for battery-backed systems that require extended runtime.

3.3 Precision Electronic Instruments

Digital multimeters, oscilloscopes, and data loggers demand accurate voltage delivery to maintain measurement precision. The MP-U36S05-PS’s ±2% load regulation ensures stable output even as the load changes (e.g., when a multimeter tests different circuits), while low electromagnetic interference (EMI) compliance (CISPR 22 Class B) prevents signal distortion in sensitive measurements.

3.4 Compact Commercial Devices

Point-of-sale (POS) terminals, LED display controllers, and small appliances benefit from the power supply’s ultra-compact size. Its bare board design fits inside tight enclosures (e.g., POS terminal casings), and fanless operation ensures quiet performance in retail or office environments.

4. Installation Guidelines: Ensuring Optimal Performance

Proper installation is critical to maximizing the reliability of the MP-U36S05-PS 36W Ultra-Compact AC-DC Bare Board Power Supply. Follow these technical steps:

4.1 Mounting Requirements

4.2 Wiring Specifications

4.3 Initial Testing

5. FAQ: Common Questions About the MP-U36S05-PS

5.1 Can the MP-U36S05-PS operate with DC input instead of AC?

Yes—the power supply supports 120-373VDC input, making it suitable for solar energy systems or industrial DC buses. Ensure correct polarity (positive to L, negative to N) to avoid component damage.

5.2 What differentiates the MP-U36S05-PS from other MP-U36SXX-PS models?

All MP-U36SXX-PS series models share the same 36W power rating, 85-264VAC input, and 3000VAC isolation. The only difference is output voltage: the MP-U36S05-PS offers 5V/6A, while the MP-U36S12-PS provides 12V/3A, and the MP-U36S24-PS delivers 24V/1.5A. This consistency simplifies design standardization.

5.3 Is a heatsink required for operation at +60°C?

At full load (5V/6A) and +60°C, a heatsink is recommended to keep the board temperature below the OTP threshold (+85°C). ShwayPCB offers a compatible 76×40×5mm aluminum heatsink that reduces temperature by 15-20°C, ensuring long-term reliability.

5.4 Can the MP-U36S05-PS be used outdoors?

The bare board design is not waterproof, so it requires an IP65-rated enclosure for outdoor use (e.g., weather stations). Its -25°C to +60°C operating range handles outdoor temperature fluctuations, but protection against rain, dust, and humidity is essential.

5.5 What does the 3-year warranty cover?

ShwayPCB’s 3-year warranty covers defects in materials and workmanship for industrial use (8 hours/day, 5 days/week). If the power supply fails within the warranty period, ShwayPCB provides a replacement or repair, plus technical support to diagnose root causes (e.g., voltage transients, overloads).

6. Conclusion

The MP-U36S05-PS 36W Ultra-Compact AC-DC Bare Board Power Supply from ShwayPCB sets a new standard for industrial power solutions, combining compact design, global compatibility, and robust protection to meet the demands of modern industrial and commercial systems.
