IntelliPass and IntelliDisconnect Drives
H-Max Series IntelliPass Drives H-Max Series IntelliDisconnect Drives
The IntelliPass electronic bypass is a two or optional three contactor design using a 24 Vdc XT Series contactor with an optional manual override switch that allows the unit to run in bypass without the H-Max Series drive. The IntelliPass construction features allow for easy installation, reliable operation and serviceability with additional onboard wire space, and removable conduit plates with knockouts. more info
The IntelliPass software parameters utilize engineering units common to the HVAC industry. Onboard startup wizard guarantees flawless commissioning with plug and play screen entry. Available in NEMA/UL Type 1 and Type 12 with optional pre-engineered operator devices to meet all customized specification requirements. more info

Application Description

The H-Max Series drive was designed specifically for HVAC pump and fluid control applications. It is intended to be used on variable torque loads with the intent of moving air or liquids. With this in mind,
the H-Max drive has onboard I/O pre-programmed to meet the common needs for these applications. The H-Max drive supports items such as standard speed control, PID functionality, as well as multi-motor applications. The drive easily supports interlock, second motor parameter set, as well as fire mode functionality.

Key Feature
Active Energy Control Algorithm Eaton’s H-Max Series drives have been designed to provide industry leading energy saving solutions. Not only is the drive ultra-efficient, the drive seeks the most efficient operating point of the motor, minimizing energy loss in the windings per the given load requirements. This is an Eaton protected control algorithm exclusive to H-Max drives.
