Strange power problem

[KandS]

Hi,
What is your 11V to 15V supply?

Tom...

It will normally be a 12v 15A but will have a lead acid battery as a backup in case of mains failure

Hi,
What is your 11V to 15V supply?

Tom...

It is a per-made 12v 15A psu but will have a lead acid battery to take over in the event of power failure

Is your 9V supply able to provide enough current?

Is your 9V supply able to provide enough current?

The total peak current draw is around 380mA so the regulator is operating well within its range

The 12v supply is not the problem, at present on the test bed it comes from an RS Components Workshop PSU
