Since the voltage difference between X2 and X3 is 18 VAC, this buck transformer with leads can be used to buck or boost the output voltage as shown in table below. For example if the input is 102 VAC, the output can be boosted to 120 VAC at 7.5 KV power rating.

 

Input Voltage,
(X1, X2)
Output Voltage,
(X1, X3)
120 VAC 138 VAC
112 VAC 130 VAC
108 VAC 126 VAC
104 VAC 122 VAC
102 VAC 120 VAC
