48 V DC/AC inverter Telecom systems 1 kVA - 27 kVA

Powernet DAC60000 dual series

inverter_custom2 Powernet program of modular Inverters intended for Telecom applications, using 48 V or 60 V battery supply. The inverter system can be dimensioned from redundant N+1 system 1500 VA up to 27 kVA. The system can be fed mainly from the grid and via a AC/AC static switch switch over to battery supply without delay. Additional modules for fuse distribution is also available. The system is modular and pluggable. The system can be remotely status monitored locally or via Internet.
