INV-T Three Phase Series
The Sure-Lites INV-T Three Phase Series represents the highest performance in uninterruptible technology while the transistorized inverter is providing power protection. Ready for virtually any emergency with this stand by power system, this pulse-width modulated inverter has a two millisecond transfer time. The AC in to AC out operating efficiency is typically 98 percent, well above a typical fast transfer inverter. The internal construction of each cabinet consists of an AC-to-DC battery charger and a DC-to-AC inverter.
