Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IP+ | passive | Current sampled positive input, one of two pins (1-2) of the primary conductor with 0.9 mΩ typical resistance, rated 600 VPK relative to GND. |
| 2 | IP+ | passive | Current sampled positive input, one of two pins (1-2) of the primary conductor with 0.9 mΩ typical resistance, rated 600 VPK relative to GND. |
| 3 | IP- | passive | Current sampled negative input, one of two pins (3-4) of the primary conductor; current flowing from IP+ to IP- is positive. |
| 4 | IP- | passive | Current sampled negative input, one of two pins (3-4) of the primary conductor; current flowing from IP+ to IP- is positive. |
| 5 | GND | power_in | Ground reference for the signal side, isolated from pins 1-4 by 3500 VRMS. |
| 6 | VZCR | output | Zero current reference signal output of 2.500 V typical, with 400 µA max source and 3000 µA max sink current. |
| 7 | OUT | output | Analog voltage output equal to VCC/2 plus sensitivity times IP (400 mV/A for 5A to 40 mV/A for 50A parts), with load of at least 1.5 kΩ and at most 1 nF. |
| 8 | VCC | power_in | Power supply input, 4.5 V to 5.5 V recommended (7 V absolute maximum). |
