Mechanical Specifications - Adaptive Frequency Drive Qty: 1

TRANE Air Cooled Adaptive Frequency Drive (AFD) The Trane AFD is an air-cooled, microprocessor based pulsed width modulation design. The AFD is both voltage and current regulated. Output power devices: IGBT transistors.

The AFD ships completely assembled, wired and tested to the job site. Patented Trane AFD control logic is specifically designed to interface with the centrifugal water chiller controls. AFD control adapts to the operating ranges and specific characteristics of the chiller, and chiller efficiency is optimized by coordinating compressor motor speed and compressor inlet guide vane position. Chilled water control and AFD control work together to maintain the chilled water setpoint, improve efficiency and avoid surge. If a surge is detected, AFD surge avoidance logic will make adjustments to move away from and avoid surge at similar conditions in the future. Use only copper conductors for terminal connections.

Failure to do so may cause corrosion or overheating, and starter damage.

Remote (Free Standing) AFD Design Features

* NEMA 1 ventilated enclosure with hinged doors, is tested to a minimum short circuit rating (SCR) of 65,000 amps. The AFD includes an overcurrent device with a minimum AIC rating of 65,000 amps. The entire package is UL/CUL listed.

Other AFD features include:

* Simple modular construction.

* Design access from the front and left

* The drive is rated for nominal chiller voltage +/-10%.

* Displacement power factor - minimum of .97 at all loads.

* Minimum efficiency of 97% at rated load and 60 hertz.

* Soft-start; linear acceleration; coast to stop.

* Adjustable frequency from 38 to 60 hertz.

* All control circuit voltages are physically and electrically isolated from power circuit voltage.

* 150% instantaneous torque available for improved surge control.

* Output line-to-line and line-to-ground short circuit protection.

In addition, on the AFD enclosure, there is a display that can be utilized by operators as needed and it includes a full comprehensive list of AFD parameters.

Designed for top entry line power and top exit load cables. The load cable connections are "bolted" type.

Environmental Ratings:

* 14F to 104 (-10C to 40) operating ambient temperature

* Altitude to 1000m, amperage derate of 4% per every 1000 meters above 1000 meters up to 3000 meters

* Humidity, 95% non-condensing
