Feature Highlights

N/A Harmonic Mitigation

  • Built-in 5% line impedance for input harmonic reduction.
Noise Filter
  • On board EMI/RFI filter complies with IEC 61800-3 restricted distribution for first environment.
Serial Communications
  • Embedded BACnet communications (BTL Certified), along with Modbus/Memobus, Metasys and Apogee FLN.
  • Plenum Rated (UL 1995). Seismic Rated (IBC 2006 - Certification 12/2011). Made with RoHS compliant materials.
Internal Real-Time Clock
  • Time and date stamping for events, along with timer controls for starting stopping and speed changes without the need for external controls.
PI Feature
  • Maintains a set point for closed loop control of fans and pumps for pressure, flow or temperature regulation and eliminates the need for a closed loop output signal from a BAS. Independent PI to control an external device in the system.
LCD Operator
  • 5-Line 16 character alpha-numeric, easy to read and understand display, with Hand-Off-Auto functions.
Carrier Frequency
  • 5 kHz carrier frequency with dynamic noise control for quiet motor operation.
Application Macros
  • Choose from pre-configured set up macros to match the application for quick and easy set up.
Sealed Heatsink
  • Allows for drive to be mounted in a NEMA 12 enclosure with heatsink external.
