central goal of Hitachi's development work on the L300P series:
To achieve optimum economical efficiency for standard V/f-applications.
The result is an inverter that is among the smallest of its
class. In a compact housing, the L300P integrates a wide range
of standard features. For instance, a unique power supply
control for improved CE-EMC characteristics, PID control for
automatic control of important process parameters, an auto-energy
saving mode for optimal energy efficiency, to name only a
These features make the L300P the inverter
of choice for all applications which call for maximum reliability:
for fans and pumps, heating and air-conditioning and all
process engineering tasks related to flow control.
