3.4.2.4
Input Current:
This is a readout of the input current,
measured in amps per phase.
3.4.2.5
Bypass Voltage
This is a readout of the bypass voltage
V
L–N
for 50Hz or V
L–L
for 60Hz.
3.4.2.6
Input/Output Frequency
A readout of the input and output frequency
in Hz.
3.4.2.7
Inlet Temperature
A readout of the inlet temperature in
C.
3.4.2.8
Rectifier/Booster Link Voltage
Rectifier link voltage is 205 VDC
10%.
If there is an increase to about 212 VDC, it
indicates the batteries are being charged. If the
voltage goes above 229 VDC, the rectifier will shut
down. (These values are subject to change
according to battery type.)
Booster link voltage is 400 VDC
10%. If the booster voltage goes above 450 VDC
or below 350 VDC, the inverter will shut down and the UPS will transfer to bypass.
3.4.2.9
Battery Amps
A positive number indicates battery
charging; a negative number indicates discharging
(possibly because UPS is operating on battery
power).
3.4.2.10 Maximum Output Crest Factor
Displays maximum output crest factor of the
load on the UPS.
