Product Description

Model 943A Bidirectional Current Transducer provides an isolated 0 to ±5Vdc output proportional to the DC input current.  The transducers have an input current range from ±100A to ±1000A and the transducers withstand, without performance degradation or damage, a continuous overload of ±5000Adc.

The 943A Series delivers high performance accuracy over a temperature range from -55°C to +85°C and measures input current with a frequency range from DC to 350kHz.  The sensors operate with a supply voltage of ±15Vdc ±1Vdc and produce the applicable output within 1u-second.  The unit’s powder coated aluminum housing, with the internal components encapsulated creates a rugged and durable transducer, withstanding environments of moisture, humidity, vibration, shock and altitude.

The 943A Bidirectional Current Transducer comes standard with a 1.38” (3.51 cm) thru-hole and are available with a barrier or connector interface, with the connector options available with mating connectors.
