Description:
The ESI 48/120V inverters are single phase, fan-cooled inverters. They convert -48 Vdc from power or backup
battery systems to an uninterruptible AC voltage. The outstanding dynamic performance matches the supply
requirements for state-of-the-art telecom equipment. The inverter is available in two sizes (1kVA or 2kVA), providing
a cost effective and reliable solution.
