Product Description

Model S939 Bidirectional Current Transducer, with removable yoke, provides an isolated 0 to ±5Vdc output proportional to the DC input current. The transducers have an input current range from ±500Adc to ±5000Adc and the transducers withstand, without performance degradation or damage, a continuous overload of ±10kAdc.

The S939 Series delivers performance accuracy over a temperature range from -40°C to +85°C, operates with a supply voltage from +11Vdc to +32Vdc, are low powered and produce the specified output within 200µ-seconds. The unit’s molded construction, with the internal components encapsulated, creates a durable transducer, withstanding environments of moisture, humidity and shock.

The S939 Bidirectional Current Transducer comes standard with a 2.20” (5.59cm) removable yoke, allowing for uninterrupted operation installation, which makes this transducer ideal for existing or retro-fit applications, as well as moveable multi-point monitoring. The transducers are available with a barrier and connector interface with the barrier accepting wire gauges from 12-26. For the connector option, a mating connector is available.
