Eaton's H-Max Series VFD has software and hardware designed specifically for the HVAC pump industry. The ultra-efficient DC capacitor and power structure allow the drive to consume less energy. The I/O configuration includes removable terminal blocks. The main control board has six digital IN, two analog IN, one analog OUT, three relay OUT and accepts two additional I/O or communication boards. In addition, the control board has built-in RS-485 and Ethernet communication. In addition, it has an Active Energy Control Algorithm to maximize motor efficiency.
