Product introduction： LH1 is a Rogowski Coil integrator dedicated to medium frequency and power frequency welding machines, which can be combined with various types of Rogowski coils. It is designed for pulse welding current measurement. It can measure the welding current signal. The output voltage is proportional to the pulse current signal. The integrator needs power. The output value is 0-10vdc. It also has the characteristics of direct connection with oscilloscope and sampling system. Application： Advantage： Ø Measuring device, laboratory instrument Ø Pulse welding machine protection Ø Welding machine control Ø Pulse welding machine current monitor Ø Pulse waveform analysis Ø Accuracy: 2%; Ø Wide power supply: 4-12v DC; Ø High bandwidth: 50Hz ~ 10kHz; Ø Zero drift is as low as 10mV.
