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 25ºC.
- 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. Standby Power: 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 are the input voltage and frequency requirements for this energy storage system?
The system supports a universal input voltage range of 100-240VAC with a frequency range of 50-60Hz, making it compatible with global power grids.
What safety standards does this power supply comply with?
It meets strict medical and industrial safety standards, including ANSI/AAMI ES60601-1, CSA C22.2 NO. 60601-1, IEC60601-1, EN60601-1, and AS/NZS 60601.1. It also holds CB, cULus, FCC, CE, TUV Mark, and AU plug reports.
How does the over-current and short-circuit protection work?
For over-current (3.6A < I < 8A) and short-circuit conditions, the output enters a hiccup mode to decrease input power and prevent damage. The system automatically self-recovers once the fault condition is removed.
What quality assurance tests do you perform before shipment?
We perform 100% functional testing (including DC performance, ripple, efficiency, and protections), a 4-hour rated load burn-in test at 40ºC ± 5ºC, and a final appearance inspection on every product.
What is the operating temperature range and expected lifespan (MTBF)?
The system operates reliably in temperatures from 0ºC to +40ºC (storage: -20ºC to +80ºC). It features an MTBF of over 50,000 hours when tested at 80% load and 25ºC ambient temperature.
