The CS/CSS series of current sensors are AC only current sensors that measure the RMS level of the current passing through the aperture. These sensors are used as level detect devices, and are adjustable by a potentiometer, with the output being an electronic relay. These sensors provide electrical isolation between the circuit being measured and the output. This CSS family of current sensors have the extra feature of clamping capabilities for easy installation. | Measuring Circuit | Units | CS-150 | CSS-150 | | Full scale (FS) ac peak | +A | 150 | 150 | | Frequency range | Hz | 6 to 100 | 6 to 100 | | Accuracy (at +25°C) | % FS | 5 | 5 | | General Information | Units | CS-150 | CSS-150 | | Operating temperature range | oC | -50 to +65 | -50 to +65 | | Weight | grams | 98 | 121 | Due to continuous process improvement, specifications are subject to change without notice. |
