The JS17F-RMS is a current transducer 4-20mA output series designed for the electronic measurement of AC waveform currents, with galvanic isolation between the primary circuit (power) and the secondary circuit (measurement). It has a 4-20mA DC output proportional to the RMS value of the primary current.

Note
• Current transformer and RMS circuit in a single case
• Choice of primary current ranges: 5 to 500A RMS
• Choice of standard output types: 4-20mA
• Accuracy: <2% of nominal primary current
• Bandwidth: 50/60 Hz
• In the 17 mm size, this product can be ordered with either a ferrite or silicon steel core. Ferrite is less expensive, and picks up low current better. Silicon steel is longer lasting, and its accuracy is less sensitive to temperature. Unless you would like to special order the product, we have chosen the combinations for you that we recommend for typical usage. F = Ferrite and S = Silicon steel.
