Current transducers offer fast broadband response
The transducer offers 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. (170 grams) maximum. The units can be powered by any DC voltage
within the range of +10VDC to +34 VDC, eliminating the need for a
negative power source. During normal operation and at overloads up to +/- 5,000 ADC, the transducer draws a maximum of 8mADC.
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.
This transducer features 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 G-RMS and shock of 50 g
11 m-sec half sine pulse.
The 929 Series is available in eight models with input current ranges from 0 ADC to +/- ADC through 0 ADC to +/-400 ADC.
The transducers come standard with five-pin terminal barrier and a 0.75”
(20 mm) pass-through aperture; optional six-pin connectors or nine-pin
D-Sub connectors are also available. For more information visit, www.a-a-c.com.
