CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The primary function is to provide temporary power to a storage controller during a power loss, allowing it to flush cached data from volatile memory to non-volatile storage (e.g., flash) to prevent data corruption or loss.
Typical backup times range from 30 to 120 seconds, depending on the amount of cached data (4–16 GB) and the controller's power consumption. These are reference ranges; actual values must be confirmed with the manufacturer.
The rechargeable lithium-ion battery cells have an expected service life of 3–5 years, after which replacement is recommended. The actual life depends on usage patterns and environmental conditions.
The module operates in ambient temperatures from 0–55 °C, with storage temperatures from -40–85 °C, and non-condensing relative humidity of 5–95%. It has an ingress protection rating of IP40–IP50 per IEC 60529.
