Inverter selection when multiple inverters are to be connected

Be sure to use a high power factor converter with the capacity higher than the total capacity of the inverters connected. (Note: One or more of the inverters... More Details >>

Connecting multiple inverters to single high power factor converter

Up to 6 units. If you connect 7 or more inverters, the permissible output of control signals is exceeded. Be sure to use a high power factor converter with t... More Details >>

Protective functions

Protective functions against the power supply fault, overcurrent, element fault, undervoltage, and transistor thermal fault (inverter protection) are availab... More Details >>

Protective functions

When the protective function works, the inverter is stopped (output shutoff) by the RDY signal. More Details >>

Size

The high power factor converter itself is almost same size as general-purpose inverter with the same capacity (FREQROL-A200 series), however, an additional s... More Details >>

Harmonic suppression guidelines for power supply

Since the high power factor converter uses the self-excitation three-phase bridge (voltage type PWM control) circuit configuration (type), the conversion coe... More Details >>

Accessories and inverter with built-in high power factor converter

If the reactor 1, outside box, and reactor 2 are contained in the same case as the high power factor converter, the unit becomes larger and heavier while fre... More Details >>
