Tapchanger Control
The M-0329B LTC Backup Control prevents a defective LTC tapchanger control
from running the voltage outside the upper and lower voltage limits and,
in addition, will prevent the line drop compensator from raising the voltage
too high under full load or overload conditions. Selectable bandcenter
and deadband settings allow the M-0329B to match any transformer control.
The M-0329B responds to a voltage excursion within 0.2 seconds and operates
within ±1% voltage accuracy over a range of -40° to +80°C.
