Lenze AC Tech AC Drives MCH for HVAC MCH Bypass Models NEM
The Lenze AC Tech MCH Series variable frequency drive has been specifically designed for HVAC loads such as fans, pumps and cooling towers. The application specific keypad offers easy operation. Features especially useful for fan or pump applications include:
  • HOA keys to mimic traditional Hand, Off, and Auto functions
  • PID set point control
  • Hour and kWh meters
  • 2 character plain English backlit LCD display with adjustable viewing angle

The MCH Series Drive with Bypass package allows the motor to be operated "across-the-line" for critical applications where a redundant means of motor operation is required. This option is factory assembled and wired in a NEMA 1 enclosure. The 3-contactor design allows the drive to be removed if required for service, while the bypass is left in place to operate the motor.

Expand the capabilities of your MCH Drive with the following options.

  • Dynamic Braking: for faster stopping or deceleration
  • Remote Keypad / Display
  • Communications: The standard MCH Series drives all contain RS-485 Modbus RTU communications. Other popular HVAC communication protocols are optionally available in the MCH Series. The protocols include Johnson Controls Metasys N2, Siemens P1, BACNet and Echelon LONWorks.
