Pure Sine-Wave Backup System

Designed for backup power in mobile systems, the GP-I-3000C Series inverters deliver pure sine-wave power to handle sensitive loads and improve ac equipment performance.

The 300-W units come in 12 or 24-V configurations in 115 or 230-Vac versions, with PFC on the ac input. The adjustable inverters are fully regulated to 1.5% or better and feature true sine-wave output with high-speed transfer switch, builtin three-stage battery charger with adaptive charging technology, secondary charger regulator for direct PV array input, temperature-compensated charging voltage, stateofthe-art remote sensing, integrated lowvoltage battery cutoff, and overload/ temperature/reverse polarity/short-circuit protection.
