UPS general description & installation
OMX76013 REV. A 9
2.2.3 Inverter
It converts the continuous voltage coming from the rectifier or from the battery into
alternating voltage stabilized in amplitude and frequency.
The inverter uses IGBT technology with a frequency commutation of approximately
10 KHz.
The control electronics is completely digital and uses a 16 Bit P, that, thanks to its
processing capability, generates an excellent output sine-wave, which has a very low
distortion even in presence of loads having high crest factor currents.
2.2.4 Battery charger
The battery charger control logic is completely integrated inside the total-controlled
rectifier control board; the battery is charged, according to the DIN 41773 Standard,
every time it has been partially or completely discharged and it is kept floating, even
when it’s charged, to compensate for any autodischarge.
2.2.5 Static bypass
It’s designed to transfer the load between INVERTER and MAINS, and vice-versa,
without break, and uses SCR’s as power commutation elements.
2.2.6 Manual bypass
It‘s used to by-pass the UPS, supplying the load directly to the mains in case of
maintenance or serious failure.
WARNING
The sequence of bypass switching must be carried out with respect to the procedure
indicated on the UPS and in the chapter “Start-up, shut-down and manual bypass”. The
manufacturer cannot accept responsibility for damages arising from incorrect operation.
2.2.7 Front panel
The front panel of the UPS, consisting of a four row alphanumeric displays plus a
keyboard, allows the complete monitoring of the UPS status and the setting of the
parameters.
The mimic diagram helps to understand the operating status of the UPS.
