Sencore AC Powerite PR57 Variable Isolation Transformer
Physical Condition: Fairly good used condition as shown. Unit has some marker on the back and shows some wear and scuffs. See photos below.
Functionality: Unit powers on. When the AC VOLTS "LINE" button is pressed, the needle on the gage zooms all the way to the right and then settles at a little over 120. If the "OUTPUT" button is pressed, the needle on the gage moves, and can be changed using the AC VOLTS knob on the right. Turned to MAX the needle goes all the way to the right and turned to MIN it goes all the way to the left. Pressing the other buttons on the front (0-1.5A 175W, 0-4A 470W, LEAKAGE "High Side" and "Low Side") changes which LED is lit on the left side of the gage, but the needle stays quiet on the left. Unable to test further. History is unknown.
