Part 2 - Products
2.01 Variable Frequency Drives
The Variable Frequency Drives (VFDs) shall be solid state, with 6-Pulse Width Modulation (PWM) output. The VFD package
as specified herein shall be enclosed in a Type 1 enclosure, completely assembled and tested by the manufacturer. The VFD
shall employ a full wave rectifier (to prevent input line notching), capacitors, and Insulated Gate Bipolar Transistors (IGBT’s)
as the output-switching device. The drive efficiency shall be 97% or better at full speed and full load. Displacement power
factor shall be no less than 0.98 at all speeds and loads.
All VFD provided shall have the following:
• Input voltage 208-240, 380-480 +/- 10% of the nominal voltage.
• VFDs shall be capable of continuous full load operation under the following conditions
− Voltage tolerance + or – 10% of specified line voltage.
− Output Frequency 0 to 150 Hz. Operation above 60 Hz shall require programming changes to prevent
inadvertent high-speed operation.
− Environmental operating conditions: 0 to 40°C, 0 to 1000 meters above sea level, less than 95% humidity, non-
condensing.
− Enclosure shall be rated UL Type enclosures or as specifically mentioned elsewhere.
