Needs an output power supply of 10...28 V dc
Primary current: from 2.5 to 1500 A ac, depending on the type
Secondary current: 4..20 mA
Internal diameter: from 35 to 105 mm, depending on the type
Busbar dimensions: from 35 to 105 mm, depending on the type
Used in power lines to obtain a current proportional to the primary current rated at 4... 20 mA in the secondary
