Description
Frequency
limits
calculation
If input frequency is above upper loss limit or below lower loss
limit, it is considered as a mains failure (turn to back-up mode).
If input frequency is within upper comeback limit and lower
comeback limit, it is considered as a mains return (return to
normal mode).
• Upper loss limit calculation:
Nom. Input Freq. + (Input Freq. Margin)
• Lower loss limit calculation:
Nom. Input Freq. - (Input Freq. Margin)
• Upper comeback limit calculation:
Nom. Input Freq. + (Input Freq. Margin) - (Hysteretic Margin)
• Lower comeback limit calculation:
Nom. Input Freq. - (Input Freq. Margin) + (Hysteretic Margin)
Example: for default values (margin 0.5 Hz,
hysteretic margin 0.2 Hz), @ 50 Hz nominal frequency.
• Upper loss limit calculation: 50 Hz + (0.5 Hz) = 50.5 Hz
• Lower loss limit calculation: 50 Hz - (0.5 Hz) = 49.5 Hz
• Upper comeback limit calculation:
50 Hz + (0.5 Hz) - (0.2 Hz) = 50.3 Hz
• Lower comeback limit calculation:
50 Hz - (0.5 Hz) + (0.2 Hz) = 49.7 Hz
Input current
limitation
Default value: 110 %
(of the Nominal Input
Current)
Programmable through control panel.
If the rectifier enters in the limitation
mode, the unit will start to discharge
batteries. In such case, the load of the
inverter will be supplied by:
1)Up to 110 % of the rated input
current by the rectifier.
2)Remaining necessary power by
battery discharge.
This situation will continue until end
of back-up time, or unit transfer to
bypass due to overload (whatever
comes first).

• Peak Limit: 300 %
Both values are programmable
through control panel:
• RMS Limit: r.m.s. inverter output
current is limited to programmed
value (150 % default), by reducing
r.m.s. output voltage.
• Peak Limit: Peak inverter output
current is limited to programmed
value (300 % default), by reducing
output waveform crest (maintaining
r.m.s. value if r.m.s. output current
is <150 %).

• In normal mode:
• UPS will deliver maximum current

this time the UPS output will be
switched off.
• If the unit is in bypass, output
