DC Current Transducers provide accuracy to 1.0% FS.

Press Release Summary:

Closed-loop Series 920 is available in 4 models with input current from 0 to ±50 Adc through 0 to ±125 Adc. Open-loop Series 921 offers 9 models with input current ranges from 0 to ±200 Adc through 0 to ±2,000 Adc. Supply voltages range from 18-28 V. Transducers automatically monitor system data remotely, making them suited for remote power stations. Input to output isolation is 500 Mohm at 500 Vdc, and operating temperature is -40 to 185°F.

New Cost-Effective DC Current Transducers from AAC Offer Tighter Accuracy Over Wider Temperature Range

Farmingdale, NY, September 2003 - American Aerospace Controls (AAC), a leading manufacturer of AC and DC current, voltage, power, and frequency transducers, has released a new series of DC current transducers that provide tighter accuracy to
1.0% FS for more stable operation over a wider temperature range of -40°C to 85°C (-40°F to 185°F), versus similar products with a temperature range of -20°C to 60°C (-4°F to 140°F).

The new Series 920 and Series 921 transducers automatically monitor system data remotely, making them ideal for local and remote power stations where feedback of operational data is required, such as in communications and cellular towers as well as in manufacturing process control systems.

The cost-effective transducers reduce labor costs both before and after installation. Each sensor uses only a two-wire connection, greatly simplifying installation, and the transducers' automatic monitoring capabilities reduce the frequency of on-site inspections and related costs. Additionally, the new transducers incorporate a sensor yoke that opens and closes, versus a pass through-hole, making them suitable for use in updating older systems.

The Series 920 transducer is available in four models with input current ranges from 0 ADC to ±50 ADC through 0 ADC to ±125 ADC; the Series 921 transducers offers nine models with input current ranges from 0 ADC to ±200 ADC through 0 ADC to ±2,000 ADC. The new transducers are available in both closed-loop (Series 920) and open-loop (Series 921) configurations, come in a wide variety of supply range voltages from 18 V to 28 V, and feature reverse polarity protection. Normal current signal is 4 mADC to
20 mADC, with 24 mADC typical at overload, and input to output isolation of 500 MΩ at 500 VDC. The new transducers weigh only 14 oz. maximum and are encased in UL 94V-0 molded plastic.

Pricing for a Series 920 closed-loop transducer starts at $199 per unit; pricing for a Series 921 open-loop transducer starts at $162 per unit. Quantity discounts are available. Delivery is 3 weeks ARO.
