Frequently Asked Questions
FAQ
What is the input voltage range for this energy storage system power adapter?
The adapter supports a wide input voltage range from 90Vac to 264Vac (standard nominal input 100-240Vac) at a frequency of 50-60Hz, making it suitable for global use.
Does this system feature over-current and short-circuit protection?
Yes, it includes built-in Over Current Protection (limit point: I > 2.6A) and Short Circuit Protection. In both cases, the system enters a hiccup mode and will self-recover once the fault condition is removed.
What safety and EMI standards does the product comply with?
The product is fully certified and complies with international safety standards including UL62368-1, CSA C22.2 NO. 62368-1-14, IEC62368-1, and EN62368-1. It also meets EMI standard FCC Part 15 class B and EN55032.
What is the operating temperature range and expected MTBF?
The system operates reliably in temperatures ranging from 0°C to +40°C. It features an expected MTBF (Mean Time Between Failures) of at least 50,000 hours when tested at 25°C under full load and nominal input conditions.
What is the standard lead time for orders?
The standard lead time is 25 to 40 working days, depending on the specific order quantity and the timing of your order. Free samples are available upon request.
