AB Power Supply Module failuring

[DwSoFt]

I apolgize for jumping to that conclusion so fast.

The power supply fuse was protecting the powersupply, there was need to replace the breaker, but its done so no point changing it now lol.

As for the tolerance levels, we will need the exact model info for the power supply and then you could search it on the AB website for specs. the Spec sheet will tell you the tolerance.

So is that +/-35v on the 415v side or the 240v side??

usually +/= 10% anything out of that range i start looking for the why!!

Hello friends,
As i have told first time,we are using 1769-PA4 AB power supply module. One of my friends gave me a suggestion so that just replace the PS module to 1769-PB4(works on 24V DC) with input from an SMPS.Whats ur suggestion for this modification?
