Here is what I have specified (so far):

DC output Power:
300mA output minimum
Overcurrent Protected (fuse blows?)
Miswire: up to 265VAC, still operates, but miswire is indicated
Transient/Surge source: Lightning

DC Inputs 1-5:
Off Voltage: 0V
On Voltage: 12V
Miswire: up to 265VAC
Transient/Surge source: Lightning
Reverse Voltage: 12VDC

DC Outputs 1:
Off Voltage: 0V
On Voltage: 12 V
Output Max Current 1A.
Overcurrent Protected
Miswire: up to 265VAC, still operates, but miswire is indicated
Transient/Surge source: Lightning

DC Outputs 2-3:
Off Voltage: 0V
On Voltage: 12 V
Output Max Load: 1kohm resistive
Overcurrent Protected
Miswire: output protected up to 265VAC, still operates, but miswire is indicated

attached is my input circuit utilizing a rectifier / dep mode fet / opto, but it doesn't indicate a miswire.

also, i really like using a comparator input so i can set the threshold voltage. maybe i can't have it all?


Please advise if you have a good suggestion.
