PART 2: PRODUCT
2.01 Manufacturers
A. The AC Drive shall be provided by Square D Company, Class 8839, Econoflex, or prior approved
equal. Substitutions must be submitted in writing three (3) weeks prior to original bid date with
supporting documentation demonstrating that the alternative manufacturer meets all aspects of the
specifications herein.
B. Alternate control techniques other than pulse width modulated (PWM) are not acceptable.
2.02 General Description
A. The AC Drive shall convert the input AC mains power to an adjustable frequency and voltage, as
defined in the following sections.
B. The input power section shall utilize a full-wave bridge design incorporating diode rectifiers. The
diode rectifiers shall convert fixed voltage and frequency, AC line power to fixed DC voltage. This
power section shall be insensitive to phase rotation of the AC line.
C. The output power section shall change fixed DC voltage to adjustable frequency AC voltage. This
section shall utilize intelligent power modules (IPMs), as required by the current rating of the motor.
2.03 Construction
A. The AC Drive power converter shall be enclosed in a [Type 1, Type 12 K] enclosure with top and
bottom conduit knockouts with a circuit breaker disconnect, industrial rated operator controls, user
terminal strip connections and bypass controls [if required].
B. The enclosure shall provide dedicated user terminals for power and control device connection.
