    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.
