I've started testing the Mt Wombat PSU upgrade. This is intended to become the new main power supply, and the two 30A motorola units will revert to backup status.
The PSU is built in a 3U rack with mains filter and a blocking diode on the output.
The mains input filter is a Schaffner
The power supply itself is a Meanwell
And the output diode is an IXYS Dual Diode Module 2x120A 1600V TO-240AA, we are only using one of the diodes in the pacjage.
General arrangement within the enclosure.
For testing I am using a carbon pile load, with the internal timer removed. It's rated at 500A for a few seconds. I'm currently testing at 50A, but the carbon pile soon warms up.
Time to start cleaning up the workbench.
