MASTERGUARD Series C
UPS Systems from 10 to 60 kVA
12. Special Versions
12.2 LAM-version
Series C – LAM includes two internal
transformers for isolation and voltage
adaptation from 400V to 208/220V
phase to phase.
DESCRIPTION
These transformers are installed in
place of batteries (10-40 kVA): the one
on the input (isolation transformer)
allows full galvanic isolation and
voltage adaptation (208/220 primary
side, 400V secondary side), the one
Unit
kVA
on the output (auto-transformer)
allows voltage adaptation (400V
primary side, 208/220V secondary
side). Technical data will change
accordingly to the following table.
