FAQ:

What is the difference between desktop and open-frame power supplies?

Desktop power supplies are external adapters located outside the equipment, while open-frame power supplies are installed inside an OEM system or enclosure. Desktop solutions are typically easier to replace, while open-frame designs offer more flexibility for internal installation, cooling and high-power applications.

Which series should I choose for compact external equipment?

The HPA65, HPA90 and HPA120 series are designed for external desktop applications requiring 65W, 90W or 120W power output. They are suitable for equipment that benefits from plug-and-play power replacement and external servicing.

Which series is suitable for high-output internal system designs?

The HBA360 and HBA600 series are designed for internal OEM systems requiring high-density power delivery, compact installation and flexible Open-Frame, U-Chassis or Top Fan configurations.

What is a Switching Power Supply and How Does It Work?

A switching power supply, or SMPS, converts AC power into stable DC output using high-frequency switching technology. Compared with linear power supplies, it offers higher efficiency, smaller size, lower heat generation, and wider input flexibility. Key stages include rectification, filtering, PFC, high-frequency switching, voltage transformation, and output smoothing, making it ideal for medical, industrial, EV, and ITE applications.

Can these power supplies be used in medical and ITE equipment?

Selected Sinpro models are designed for medical and ITE applications. Final product selection should always be confirmed according to the applicable safety approvals, output requirement, inlet type, operating condition and end-equipment certification target.

What are the Standard Medical Power Supply Requirements?

Medical power supplies must meet IEC 60601-1 requirements to protect patients, operators, and connected equipment. Key considerations include 2xMOPP or 2xMOOP insulation, controlled leakage current for Type B, BF, or CF applied parts, and IEC 60601-1-2 EMC compliance. Stable output, low noise, thermal management, and built-in fault protection also support safe, reliable long-term operation.

Class 2 Power Supply and How It Differs from Class II

Class 2 and Class II power supplies are often confused, but they refer to different safety concepts. Class 2 focuses on limited output voltage, current, and power to reduce fire and shock hazards. Class II focuses on double or reinforced insulation, allowing safe operation without a ground connection. Understanding both helps select the right power supply for low-voltage, medical, ITE, and industrial applications.

Learn More About Class 2 vs Class II
What information should I provide when selecting a power supply?

Please provide your required output power, output voltage, cooling method, installation space, operating temperature, application type and safety requirements. This information helps identify the most suitable desktop or open-frame power platform.
