Determining a Power Source
Determine how to power the MicroMax interrupter using one of these possible sources:
1.
Rectifier - with power turned on to the rectifier, use a voltmeter to locate a power source
across two available AC taps. The interrupter requires 8-42 V AC or 10-60 V DC.
2.
A 120 V AC convenience outlet to use with the 12 V DC wall adapter.
3.
A DC source, such as a 10-60 V DC battery.
