Vector PAM Inverter
(I-PAM + vector control)
I-PAM Control
(PAM+IPM)
The voltage of the compressor and the timing of the
current connection are enhanced. This is the advanced
technology of PAM control system which improved the
maximum compressor speed and operation efficiency.
IPM board made the conventional inverter PAM control
possible to obtain high-voltage and high power at the
time of operation starts. The preset temperature is kept
with low voltage during the stable operation.
Thus, higher performance and more energy saving are
realized than the current inverter models.
“I-PAM (Intelligent power module-Pulse Amplitude Modulation)”
Energy saving and speedy heating only possible by I-PAM
Attain your desired temperature just 1/3 of
time comparing to our conventional inverter models.
