Lenze AC Tech MCH Series Drives for HVAC
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 is available as a
basic drive by itself or as part of a package.
The MCH Series Drive with Option Box
package allows options such as input disconnect switch, input fuses, and/or
input line reactor to be added to the drive. These options are factory
assembled and wired in a NEMA 1 enclosure.
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.
