I. Core Parameter Comparison: A "Hard Power" Showdown Between New and Old Models

To help you quickly grasp the upgrade highlights, we first present the key differences between the UES48DZ-SPA and UES48-SPAZ through a detailed 

comparison table:

II. New Model UES48DZ-SPA Series: In-depth Analysis of Four Core Advantages

1. Safety Certifications & Isolation Protection: The "Cornerstone of Trust" for Medical Scenarios

The UES48DZ-SPA Series inherits and strengthens the safety genes of medical power supplies, holding IEC60601-1, ANSI/AAMI ES60601-1 and other medical-grade safety certifications, while complying with Class I & II protection levels.

With an isolation voltage of ≥56,800VDC, it far exceeds the insulation design of the old model. In the high-voltage working environment of medical equipment, it builds a more robust "electrical barrier" for the safety of medical staff and patients. Combined with a leakage current of ≤100μA, it fully meets the stringent requirements for home medical devices and can be safely used in equipment that directly contacts the human body, such as monitors, endoscopes, and dental X-ray machines.

2. Energy Efficiency & Power Consumption: A "Energy-Saving Pioneer" for Green Healthcare

As a Level VI energy-efficient product, the UES48DZ-SPA has a standby power consumption of ≤0.1W. In medical devices that require long-term standby (e.g., oxygen concentrators, ultrasonic diagnostic equipment), it can effectively reduce energy consumption.

In terms of power conversion efficiency, the series achieves 87.77% (compared to approximately 88.7% for the old model). Although there is a slight difference, it actually reflects a better balance among "energy efficiency, size, and heat dissipation" – a minor optimization in efficiency is exchanged for comprehensive upgrades in size, weight, and heat dissipation performance.

3. Structural Design: A "Dual Pursuit" of Compactness and Reliability

The new model achieves a breakthrough upgrade in dimensions: the compact body of 110(L)×51.5(W)×33.1(H)mm is 12mm shorter than the old model, and weighs only 205g (a reduction of approximately 100g). It is more suitable for the "miniaturization and integration" trend of modern medical equipment (e.g., portable ultrasound, handheld ECG devices).

Meanwhile, its MTBF exceeds 100,000 hours, and it has passed the MIL-HDBK-217 military reliability standard test. It can operate stably in a wide temperature range of -40~80℃, and its reliability under extreme working conditions is far superior to the old model.

4. Electrical Performance: A "Comprehensive Upgrade" of Adaptability and Protection

• Input & Output: The input voltage range is expanded to 90-264VAC, adapting to power grid fluctuations in different regions worldwide; the output voltage covers 9.0-35.1V, with a current of 0.01-1.55A and a stable power of 48W, meeting the power supply needs of various medical equipment.

• Protection Mechanisms: The overcurrent protection range is upgraded to 110-200% of rated power with auto-recovery, overvoltage protection is 120% maximum cycle input reset, and short-circuit protection adopts hiccup mode. Multiple protections can effectively respond to sudden load abnormalities in medical scenarios (e.g., equipment short circuits, instantaneous overloads).

III. Application Scenarios: From "Adaptation" to "Optimized Matching"

The old UES48-SPAZ Series has been widely used in scenarios such as optical machines, oxygen concentrators, and monitors. Building on this foundation, the UES48DZ-SPA Series further expands the adaptability to highly integrated and portable medical equipment:

• Endoscopes, Dental X-ray Machines: The compact body can be embedded inside the equipment to save space;

• Electrosurgical Units, X-ray Equipment: High isolation voltage and low leakage current ensure electrical safety during surgeries and diagnostic processes;

• Portable Ultrasound, Handheld ECG Devices: Lightweight design + wide temperature operating range meet the needs of mobile medical scenarios.

IV. Selection Recommendations: How to Determine if an Upgrade is Needed?

We strongly recommend prioritizing the UES48DZ-SPA Series if your equipment falls into the following categories:

1. Equipment requiring miniaturization and portability design, with high sensitivity to power supply size and weight;

2. Equipment used in extreme temperature or high-altitude environments (e.g., oxygen concentrators in plateau areas) with strict requirements for power supply reliability;

3. Equipment intended for global sales, with high requirements for safety certification coverage and input voltage range;

4. Class I/II medical equipment that directly contacts the human body (e.g., monitors, electrosurgical units) with strict requirements for electrical safety and isolation performance.

V. Conclusion: Why Choose the UES48DZ-SPA Series?

It is not just an iterative product for "new and old replacement", but also UE Electronic's precise response to the trend of "professionalization, miniaturization, and high reliability" of medical power supplies. With a more compact structure, comprehensive protection, and broader adaptability, it provides an upgraded experience from "power supply" to "empowerment" for modern medical equipment.
