Product Description

Model 929 Bidirectional Current Transducer provides an isolated 0 to ±5Vdc output proportional to the DC input current.  The transducers have an input current range from ±50Adc to ±400Adc and the transducers withstand, without performance degradation or damage, a continuous overload of ±5000Adc.

The 929 Series delivers performance accuracy over a temperature range from -40°C to +85°C and measures input current with a frequency range from DC to 350KHz.  The transducer’s operate with a supply voltage from +10Vdc to +34Vdc, produces the specified output within 1µ-second and are low powered.  The unit’s molded construction and internal epoxy encapsulation creates a durable transducer, withstanding environments of moisture, humidity, vibration, shock and altitude.

The 929 Bidirectional Current Transducers are light weight and are available with a barrier, connector or d-sub connector interface, with the connector and d-sub connector options available with mating connectors.
