PART 2 - PRODUCTS
2.1 MANUFACTURERS
A. The drive shall be designed specifically for variable torque applications from one of the
following manufacturers:
1. Siemens BT300 Series or approved equal.
2.2 VARIABLE FREQUENCY DRIVES
A. The Variable Frequency Drives (VFDs) shall be solid state, with a Pulse Width
Modulated (PWM) output. The VFD package as specified herein shall be enclosed in a
TYPE1 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.
B. All VFD provided shall have the following:
1. Input voltage 208-240, 380-480 +/- 10% of the nominal voltage.
