Original Press Release:



New Rugged Bi-Directional Current Transducers from AAC Offer Ultra Fast Broadband Response and Superior Accuracy



Farmingdale, NY, June 2004 - American Aerospace Controls (AAC), a leading manufacturer of AC and DC current, voltage, power, and frequency transducers, has released a new series of bi-directional current transducers capable of accurately following extremely fast (DC and/or AC) current waveforms. The 929 Series consumes a very low 80 to 270 mW during operation, and provides an ultra fast response to complex current waveforms in the range of DC to 350 KHz, making the transducers ideally suited for demanding environments where high speed current monitoring is needed.

The new transducers offer superior accuracy (±1.0% FS) over a wide temperature range -40°C to 85°C (-40°F to 185°F). The 929 Series features a compact, rugged, flame-retardant package that measures only 1.9" x 3.3" x 1.9" (48 mm x 84 mm x 48 mm) and weighs only 6 oz. maximum. The units can be powered by any DC voltage within the range of +10 VDC to +34 VDC, eliminating the need for a negative power source. During normal operation and at overloads up to ± 5,000 ADC, the AAC-A-5007 transducer draws a maximum of 8 mADC. The unit's input power connection can withstand a ±60 V transient power surge (T < 5 m-sec), and is reverse polarity and short circuit protected. The unit's output is capable of following IGBT currents from DC to 350 KHz with an output load of 5 KΩ to infinity, and an output impedance of 25Ω.

The new transducers feature excellent environmental characteristics to endure harsh operational conditions. Internal circuitry is epoxy encapsulated to increase insulation (500 MΩ @ 500 VDC), and to protect the unit from moisture and foreign contaminants. In addition, the transducer's case is manufactured from a molded plastic that tolerates very high temperatures, meets the UL94V-0 flammability rating, and allows the 929 Series to withstand random vibration levels per MIL-STD-810F of 12.0 GRMS and shock pulses of 50 g.

The 929 Series is available in eight models with input current ranges from 0 ADC to ±50 ADC through 0 ADC to ±400 ADC. The transducers come standard with a five-pin terminal barrier and a 0.75" pass-through hole; optional six-pin connectors or nine-pin D-Sub connectors are also available.

Pricing for a 929 Series bi-directional transducer is available upon request.
