Replaces Pennsylvania Transformer and McGraw-Edison LTC Transformer Controls.

Adaptive control feature significantly reduces number of tap changes for a given Voltage Regulation Quality Factor (VRQF)

• Provides direct mechanical replacement of the old LTC transformer control using the same four moutning studs, front door brace, and locking knob
• Provides built-in CT shorting protection
• Uses proprietary sampling to measure fundamental voltage, watts, and VArs at a rate of 20 times per second
• VAr Bias feature included to induce M-2501/A Capacitor Controls on load feeders to operate to optimize VAr profile.
