6.c.6.4.1.4 Automatic Voltage Regulation ( AVR ) Transfer Point Configuration
AVR is an automatic autotransformer function that steps up ( Boost mode operation ) UPS
output VAC when the VAC input is low and steps down ( Buck mode operation ) UPS output
VAC when the VAC input is high. During AVR, the MP2000E front panel PTS output is
constantly energized so that VAC output comes from the UPS rather than bypassing VAC
power through the power transfer switch ( PTS ). Figures 6-60 and 6-61 show the AVR Off
Settings and AVR On Settings screens.
