FIELD
DETAILS
High Voltage
Transfer Point
Setting
This is the VAC input voltage level at which the UPS switches from On
Line to On Battery.
High Limit Point VAC voltage setting at which the UPS switches from On Line to On
Battery.
High Hyst Point High Hysteresis Point — This is the VAC voltage level down to which the
VAC input must lower ( after being above High Limit Point ) before
qualifying for On Line operation.
High Gap
This is a hysteresis of the High Limit Point and the High Hyst Point.
Buck Transfer
Point Setting
With AVR Off these settings have no effect.
Buck High Point VAC voltage setting at which the UPS switches from On Line to Buck
mode operation ( step down voltage ).
Buck Low Point This is the VAC voltage level down to which the VAC input must lower
(after being above Buck High Point ) before qualifying for On Line
operation.
Boost Transfer
Point Setting
With AVR Off these settings have no effect.
Boost High
Point
VAC voltage setting at which the MP2000E switches from On Line to
Boost mode operation ( step up voltage ).
Boost Low Point This is the VAC voltage level down to which the VAC input must raise
(after being below Boost Low Point ) before qualifying for On Line
operation.
Low Voltage
Transfer Point
Setting
This is the VAC input voltage level at which the MP2000E switches from
On Line to On Battery.
Low Limit Point VAC voltage setting at which the MP2000E switches from On Line to On
Battery.
Low Hyst Point
Low Hysteresis Point – This is the VAC voltage level up to which the VAC
input must rise (after being below Low Limit Point) before qualifying for
On Line operation.
Low Gap
This is a hysteresis of the Low Limit Point and the Low Hyst Point.
AVR Feature
Setting
Turn On or Off boost and / or buck operation.
