Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IP+ | passive | Current sampled positive input, part of the primary conductor (pins 1-2) with 0.9 mΩ typical resistance, rated -600 to 600 VPK relative to GND. |
| 2 | IP+ | passive | Current sampled positive input, part of the primary conductor (pins 1-2) with 0.9 mΩ typical resistance; current flowing from IP+ to IP- is positive. |
| 3 | IP- | passive | Current sampled negative input, part of the primary conductor (pins 3-4) with 0.9 mΩ typical resistance, isolated 3500 VRMS from pins 5-8. |
| 4 | IP- | passive | Current sampled negative input, part of the primary conductor (pins 3-4) with 0.9 mΩ typical resistance; do not shunt resistors between IP+ and IP-. |
| 5 | GND | power_in | Ground reference for the supply and signal pins. |
| 6 | VZCR | output | Zero current reference signal output, source current max 400 µA and sink current max 3000 µA. |
| 7 | OUT | output | Analog voltage output equal to VCC/2 + 0.040×IP(A) V for the 50A version, 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 operating range with 7 V absolute maximum. |
