INVIS-300 Single-Phase Rectifier-Inverter
Single-phase rectifier-inverter for uninterrupted supply of remote-control and supervision equipment in MV installations.
The INVIS-300 single-phase rectifier-inverter is used in uninterrupted power-supply systems for remote-control and supervision equipment in medium-voltage installations. It combines a 48 V DC rectifier/battery charger, DC/DC converters for 24 V and 48 V DC, and a DC/AC inverter for 230 V AC supply. An optional RM relay module enables battery monitoring and protection.
-
UPS supply for MV equipment
Intended for remote-control and supervision cabinets in medium-voltage installations.
-
Three output voltages
Provides 48 V DC for batteries, 24 V DC for control equipment and 230 V AC for other loads.
-
Battery charging
The 48 V DC output is adjusted for charging battery banks at 54.6 V.
