Specification
1. Inrush Current (cold start): The inrush current will not exceed 80A at 100-240Vac input and Max load for a cold start at 25℃.
2. Efficiency: While input 115Vac and 230Vac, the average efficiency is more than 87.40%. The test point is at 25%, 50%, 75% and 100% of max load respectively.
3. No-Load Loss: While input 115Vac or 230Vac and the output is no load, the input power loss must be less than 0.1W.
4. Capacitance Load: While input 100~240Vac and capacitance load is 470uF, the adapter can turn on normally and the output is in the rated range.
5. Output Load Transient Response: the output shall not exceed 10% of the nominal output voltage, load fluctuation: from 20% to 80%, R/S: 0.5A/uS, frequency: 100Hz duration and 8mS at 80%.
6. Over Current Protection: I 3.6A＜I＜8A, The output shall hiccup when the over currents applied to the output rail, and shall be self-recovery when the fault condition is removed.
7. Short Circuit Protection: The input power shall decrease when the output rail short, the power supply shall no damage, and shall be self-recovery when the fault condition is removed.
8. Over Voltage Protection: The power supply shall protection when the output over voltage.
9. Vibration Test: 10 to 300Hz sweep at a constant acceleration of 1.0G (Breadth: 3.5mm) for 1 Hour for each of the perpendicular axes X, Y, Z.
10. Drop Test: Height: 1m; the product should be fell off on the plank with the thickness of at least 53mm, and the plank should be put on the cement ground or on the ground without flexibility. Random surface in all 3 times.
11. EMI: FCC Part18 class B, EN55032.
12. EMS: EN55035.
13. Safety Accord with: ANSI/AAMI ES60601-1, CSA C22.2 NO. 60601-1, IEC60601-1, EN60601-1, AS/NZS 60601.1.

Frequently Asked Questions
What is the global voltage compatibility of this power supply?
The system supports a wide input voltage range of 100-240VAC at a frequency range of 50-60Hz, making it compatible with power standards worldwide.
What safety certifications does the product carry?
The product is built to comply with 60601 medical and general safety standards, including ANSI/AAMI ES60601-1, CSA C22.2 NO. 60601-1, IEC60601-1, and EN60601-1. It is certified by CB, cULus, FCC, CE, TUV Mark, and holds an AU plug report.
How does the Over Current and Short Circuit Protection work?
When over current (between 3.6A and 8A) or a short circuit is detected, the device enters hiccup mode. It automatically recovers to normal operation once the fault condition is successfully removed.
What are the testing protocols for quality assurance?
Every single unit (100%) goes through a turn ON/Off test under load, a comprehensive functional system test (voltage, ripple, efficiency, protections), a 4-hour rated load burn-in test at 40℃±5℃, and a final manual appearance inspection.
What are the environmental limits for operation and storage?
The operational temperature range is 0℃ to +40℃ with 10% to 90% humidity. The unit can be safely stored in temperatures ranging from -20℃ to +80℃.
What is the expected reliability lifespan (MTBF) of the device?
The Mean Time Between Failures (MTBF) is rated at over 50,000 hours when operating under an 80% load at an ambient temperature of 25℃.
