General Use
The UES500-SPAZ-OP open board PSU series offers multiple power supply models, allowing users to choose between 2-pin or 3-pin input and fan configurations depending on the application scenario. It covers voltage requirements from open frame power supply 12V to 54V, with an average efficiency of ≥92% and a startup delay of ≤3s, providing a reliable solution for open frame SMPS needs in the medical and communications industries.

Q1: What type of power supply is the UES500-SPAZ-OP?

A: This is an open frame switching power supply, also commonly referred to as an open frame PSU or open PCB power supply. Its design utilizes an open-frame structure, facilitating integration into customer end devices for heat dissipation and mechanical mounting.

Q2: Which industries and devices are primarily suited for this open-frame power supply?

A: It is designed for industries with extremely high safety and reliability requirements, particularly for power adapters in medical equipment and information technology equipment (ITE). Typical applications include medical diagnostic equipment, patient monitors, communication base stations, and network servers.

Q3: What common output voltage options does this power supply offer?

A: It offers a variety of standard DC output voltage options, ideal for applications requiring a 12V open frame power supply or a 24V open frame power supply. Model series cover a wide range from 12V to 54V.

Q4: As an open-frame AC-DC power supply, what is its input voltage range?

A: This open frame AC DC power supply supports a wide range of AC input voltages: 80-264VAC, suitable for different regional power grid standards.

Q5: What is the product's rated power? How is it cooled?

A: The rated power is 320W under natural convection cooling; if the user provides external forced air cooling (with a fan) or use our chassis/baseplate (with a fan), the power can be increased to 500W. This flexible cooling design is a typical advantage of open frame SMPS, facilitating system integration and thermal management.

Q6: What are its safety compliance features for medical applications?

A: This product strictly complies with international medical safety standards, providing high-level isolation protection with 2 MOPP (Means of Patient Protection) and extremely low leakage current (≤100μA). It has obtained several key certifications, including IEC60601-1 and EN60601-1, ensuring its safety as a power supply for medical devices.

Q7: What are the product's reliability and lifespan?

A: According to the MIL-HDBK-217 standard, its Mean Time Between Failures (MTBF) exceeds 100,000 hours at an ambient temperature of 25°C, ensuring long-term stable operation as a core power supply board (bare board power supply) in critical applications.

Q8: How are its efficiency and standby power consumption?

A: The product’s average conversion efficiency is as high as 92%-94% (slightly different for different output voltage models), meeting Energy Efficiency Level VI standards. Its standby power consumption is very low, only ≤0.5W, which helps terminal equipment achieve higher energy efficiency.

Q9: What are the operating environment conditions for this Open Board PSU?

A: It is designed for harsh environments, with a wide operating temperature range of -30℃ to 70℃, an operating altitude of up to 5000 meters, and stable operation at non-condensing humidity of 5% to 90%.

Q10: Is it the same as a standard open-frame ATX power supply?

A: Not exactly. Although both are open-frame structures, the UES500-SPAZ-OP is a single or multi-output power supply specifically designed for industrial and medical/communication equipment. Its size, interfaces, and certifications (such as medical safety standards) differ from the standard ATX specifications used in consumer PCs.
