Hitachi i4+ Single Phase Industrial UPS Systems

I4 series of UPS systems have been designed to perform under extreme operating conditions that normally
exist in industrial environments. The use of Digital Signal Processors (DSP) has made the control loop of the
UPS system very stable, drift free and with better HMI for monitoring, control and precise settings of
parameters. High speed CAN bus interfaced sections make the system response very fast to handle the
extreme transient load conditions. Intelligent power device with sandwich bus architecture makes the
systems highly efficient and reliable.
