INV Series Long Back-Up Time EPS & Pure Sine Wave Inverter (1kW–8kW)
INV Series Long Back-Up Time EPS & Pure Sine Wave Inverter
The INV Series Long Back-Up Time Emergency Power Supply (EPS) / Static Power Inverter provides pure sine wave AC output, with nine models rated from 1kW to 8kW.
The INV Series uses CPU-controlled PWM technology and an isolation transformer. The original technical brochure describes the series as a long back-up time emergency power supply and static power inverter, with efficiency greater than 88% over the normal load range.
The series provides a preferred AC input and a model-dependent alternate DC input. Its pure sine wave output is specified at 230VAC, single-phase, with selectable 220V and 240V output settings.
Published features include intelligent four-step battery charging, LED monitoring of input, output, load and battery information, remote control functions and protection against specified electrical faults.
