Product Description
The Z1000U MATRIX HVAC Bypass combines excellent harmonic mitigation, input power factor control, and energy saving
capabilities in a design specifically suited for use in HVAC building automation applications that require reliable motor control.
The bypass package provides a Z1000U MATRIX drive in a NEMA rated enclosure with a 2-contactor style bypass to allow
motor operation from the drive or across the line. The Z1000U MATRIX drive incorporates MATRIX technology to directly
convert input AC voltage to output AC voltage. The Z1000U MATRIX drive offers real choices and benefits for green HVAC
applications.
The Z1000U features HVAC application-specific software macros, a Hand/Off/Auto LCD keypad, and a real time clock for
system accuracy. Popular building automation communication protocols BACnet, Siemens APOGEE, Johnson Controls
Metasys, and MEMOBUS/ Modbus are embedded in the drive.
