Product Description

Model S433-100 Bidirectional Current Sensor provides an isolated 0 to +3Vdc output proportional to the DC input current.  The sensors have an input current range from -100Adc to +100Adc and withstands, without performance degradation or damage, a continuous overload of one-hundred times full-scale.

The S433-100 Series delivers performance accuracy over a temperature range from -25°C to +75°C, operate with a supply voltage from +15Vdc ±1Vdc and the sensor will operate within the specified input/ output requirements with 200Aac (60Hz) on the bidirectional current input.  The unit’s molded construction, with the internal components encapsulated, creates a durable sensor.

The S433-100 Bidirectional Current Sensor comes standard with a connector interface and a 1.50” (3.81cm) removable yoke, allowing for uninterrupted operation installation, which makes this sensor excellent for existing or retro-fit applications, as well as moveable multi-point monitoring.  Mating connectors are available.

The S433-100 Series was developed for a Power Station Application: Geomagnetic Induced Current Monitoring (GIC), due to an increase in the solar flare activity cycle.
