I noticed last evening that the wall wart that comes with a lion chief set has the same plug as an mth z750 or z1000 brick.
How much power does the aux power connection on the tiu actually need? For example could I use a wall wart that puts out 18 volts for the aux power supply?
As a follow up, is the a downside to not using an mth brick, such as not having the circuit breaker?
In a somewhat related question, is there a plus/minus to using the older mth bricks labeled for 21 volts as opposed to the newer ones rated at 18?
For reference I am using a Rev I tiu, an it just came back from mth with rev 6.1 software.
All constructive insights are always appreciated,
