Thread: Voltage issues with ITPS?

I tested my itps setup today becuase i get random reboots at varying intervals.
My setup is :- 12v from car battery to 3 3a diodes in parallel, then to a 1.2ah sealed battery, then to input of ITPS, output to epia M10k in Travela C134 case with original psu.

Ignition off = 12.04v
Ignition On = 14.19v
Voltage after diodes = 13.25v
Voltage in ITPS = 13.25v
Voltage out of ITPS = 11.2 - 11.8v varies

I noticed that every now & then the O/P voltage of the ITPS drops to 10.2v for a second,
Could my ITPS be Faulty?
Would it be damaging to the psu to bridge the voltage regulation on the ITPS?

Any help would be appreciated
