1 7200M3 INVERTER MAIN UNIT
The 7200M3 is an all-digital inverter of compact size and low noise. Two types of models are available:
with digital operator (JNEP--13) and with analog operator (JNEP--14). Using the digital operator achieves
optimum drive and monitoring by changing the control constant setting. The model provided with the
analog operator is used for simple applications where no complicated constant setting are necessary. Free
kit operator (JNEP--15) is also available for sample applications.
