Low Frequency Online Modular UPS 100KVA Module Uninterruptible Power Supply UPS System
The UPS consists of the following subassemblies:
Standard is six pulse rectifier, optional is twelve pulse to reduce input current distortion.
Represents the input stage and transforms the alternating voltage of the power line in continuous voltage. The
functions carried out by the rectifier are the following:
- powering the inverter with direct current.
- charging the battery automatically. Battery charging is done in two phases: the first phase supplies 80% of
power with limited current (recharging current) and growing voltage. The second supplies the remaining 20%
of the charge with steady voltage (holding).
Recharging current is automatically limited to 15% of the capacity in Ah contained in the memory. This recharging
current imposed applies only when the total power delivered to the battery and the load does not exceed maximum
110% of Pn.
HARMONIC REDUCTION FILTER (optional)
The filter is positioned to the entry of the rectifier, allows to reduce the input harmonic distortion of the input current.
It is composed by two inductors and by a group of capacitors. The filter is protected in entry with some fusible.
Provides the reserve energy for powering the load when there is no power input to the UPS.
This is the output stage. Converts direct voltage from the RECTIFIER or BATTERY into stabilized sinusoidal
alternating voltage. It is always in operation and the load connected to the output of the UPS is always powered by the
This device allows the instantaneous automatic or manual switching of the power feed from the secured line
(INVERTER output ) to an unsecured line (BY-PASS line) or vice versa.
The STATIC SWITCH is supplied with a device, BACKFEED PROTECTION that prevents the danger of current
returns on the reserve line, in the case of Mains power failure due to a break on the SCR. The SCR are protect by
Maintenance switch, by closing the SWMB and opening the other switches SWIN, SWBY, SWOUT the UPS is excluded, maintaining the output feed.
This operation is necessary when you have to carry out maintenance operations inside the equipment, without being obliged to interrupt the power feed.
With the SWMB closed and all the other switches open, there is no voltage inside the equipment (voltages are present only in the terminal board area and in the switches area, N.B. in the threephase output version the neutral conductor is not interrupted.).
