The VPLog-i measures AC currents up to 3200A (true-RMS on a single phase power cable). The VPLog-i is very easy to use: just wrap around one of the three phases and close the snap fitting. It offers the best solution for your mobile power measurements. The VPLog-i is the only sensor on the market that offers both 4 ... 20mA and pulse outputs.
Easy and simple: Just open the power meter and wrap around the power cable you want to measure. The LED on the device blinks when the VPLog-i is powered. The rate at which it blinks is proportional to the output current. You can use one of the two outputs to get accurate power measurement results.
