The current measuring devices measure the effective value of EPM-4A current in 1-phase networks and save the maximum, average and currently required values.
At the current measurement devices EPM-4A is a CT-25 current transformer for a measuring range from 70 mA to 210A included in the delivery.
The current transformer ratio of 5/5 A to 10000/5 A and the demand time can be programd.
