Internal UPS
The BLACKBOX Portable contains an internal, uninterruptable power supply
module providing a short period of self-powered measurements sessions and/or
power supply interruptions ride-through.
The Internal UPS system contains a lithium battery for a up to 2 hours of fully-
functioning operation and a super capacitors module allowing an additional 25
seconds of short interruptions ride-through even in the case of the main battery
being fully discharged.
The battery and super capacitors modules require no maintenance and are de-
signed for a long service life. However, if the battery shows a significant de-
crease in performance, it should be replaced with a factory original. Consult with
your local Elspec agency for replacement battery ordering information. Please
refer to Replacing the Battery on page 142.
