Panasonic Inverter three phase for blower

1)Various external controls In addition to starting/stopping from the outside, it is possible to change the frequency using 0 to 5 VDC, 0 to 10 VDC, and 4 to 20 mA DC.
2) Low-noise operation The high-carrier sine wave PWM system enables operation at a low-noise level comparable to that of commercial power supply.
3) Setting the operation mode remotely A simple remote air volume adjustment switch (optional) allows you to start/stop and change the frequency remotely.
4) Up to 3 frequency jump settings If resonance occurs at a specific frequency, you can set up to 3 points to avoid that frequency.
5) Initial settings for parameters suitable for the blower Since the parameters are initially set for the blower, there is no need to make any additional settings. (Some settings are required)
6) Memorize operating frequency Even if the power is cut off once, the last operating frequency is memorized.
