Pulse frequency characteristics of terminal FM

The terminal FM output pulse is directly proportional to the inverter output frequency.With the initial setting, 1440 pulses/sec are output at 60 Hz (Pr.55),... More Details >>

Negative phase of input power supply

The power supplied to the inverter is converted into DC by the converter inside the inverter and then stored in the capacitor. Thus, reversing the phase sequ... More Details >>
