Product Description

Model S728B DC Current Transducer provides an isolated 0 to 5Vdc output proportional to the DC input current.  The transducers have an input current range from +50A to +400Adc, with a frequency range from DC to 350kHz and the transducers withstand, without performance degradation or damage, a continuous overload of 5000Adc.

The S728B delivers high performance accuracy over a temperature range from -55°C to +85°C, operates with a supply voltage from +24Vdc to +32Vdc and are ultra-fast responding. The unit’s brass alloy housing is hermetically sealed, with the internal components encapsulated, creating a rugged and durable transducer, withstanding environments of moisture, humidity, vibration, shock and altitude.

The S728B DC Current Transducer comes standard with a 0.50” (1.27cm) thru-hole, is light weight and is available with a header interface.
