Product Description

Model S629 DC Current Level Detector features an effective and accurate solution to monitor DC current. The unit is available with or without a bus bar depending on customer application. A conductor wire is either routed through a 1.5 inch thru-hole which provides non-intrusive and isolated method of measuring current or cables are connected to the bus bar for retrofit applications. After input current reaches the desired threshold, the relay is energized. Internal high precision reference guarantees reliable and repeatable measurement. The detector is calibrated at the factory to 45Adc and capable of withstanding continuous overload of 1000Adc.

The S629 Series delivers performance accuracy over a temperature range from -25°C to +75°C and operates with a supply voltage from +25Vdc to +45Vdc. The unit’s molded construction and internal epoxy encapsulation creates a durable detector, withstanding environments of moisture, humidity, vibration and shock.

The S629 DC Current Detector comes standard with a barrier interface and a 1.50″ diameter nickel plated copper bus bar.
