Specification Details
1. The range of input voltage is from 90Vac to 264Vac with a single phase.
2. The inrush current will not exceed 80A at 100-240Vac input and Max load for a cold start at 25°C.
3. While input 115Vac and 230Vac, the average efficiency is more than 87.72%. The test point is at 25%, 50%, 75% and 100% of max load respectively.
4. While input 115Vac or 230Vac and the output is no load, the input power loss must be less than 0.1W.
5. While input 100~240Vac and capacitance load is 470uF, the adapter can turn on normally and the output is in the rated range.
6. 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%.

Frequently Asked Questions
What is the input voltage range for this power supply?
The input voltage ranges from 90Vac to 264Vac (nominal 100-240Vac) with a frequency range of 50-60Hz, making it suitable for global electrical standards.
What safety and medical certifications does this product hold?
This power supply complies with the IEC60601-1 and EN60601-1 medical safety standards. It also carries CB, cULus, FCC, CE, TUV Mark, and AU plug report certifications.
Does the power supply feature over-current protection?
Yes, it features Over Current Protection (activated when current is > 3.75A). The system enters a hiccup mode during an over-current event and self-recovers once the fault is removed.
What is the average efficiency and standby power consumption?
The average efficiency is greater than 87.72% at 115Vac and 230Vac input. When the power supply is at no load, standby power loss is highly optimized to be under 0.21W (and less than 0.1W in specific configurations).
What is the expected lifetime (MTBF) of the device?
The MTBF (Mean Time Between Failures) is rated at a minimum of 50,000 hours at a 25°C ambient temperature, operating under full load and nominal input conditions.
Can the packaging be customized for bulk orders?
Yes, standard packaging includes a PE bag, small white box, cardboard, and paper case. However, we can accommodate customized packaging designs based on specific customer requirements.
