01 / OVERVIEW
Measure current without opening the primary circuit.
|
The primary conductor passes through the central aperture. A magnetic compensation circuit develops a secondary current proportional to the primary ampere-turns, maintaining electrical isolation between the high-current conductor and the measurement electronics.
The sensor supports bidirectional DC, alternating current and impulse current with rapid response and a broad frequency range.
|
| AC and DC measurement One sensor covers steady and changing current. |
High electrical isolation Primary and secondary circuits remain separated. |
Fast dynamic response Suitable for control and protection loops. |
| CURRENT RANGE | |
| Nominal primary current | 500 A.t rms |
| Continuous measuring range | 0 to +/-1200 A.t |
| AC peak range | 0 to +/-1275 A.t |
| OUTPUT AND SUPPLY | |
| Nominal output at 500 A.t | 100 mA |
| Supply voltage | +/-15 to +/-18 Vdc |
| Current consumption | 20 mA plus output current |
| ACCURACY AND SPEED | |
| Accuracy at 25 degrees C | Maximum +/-0.5% of nominal current |
| Linearity | Better than +/-0.1% |
| Response time | Better than 1 microsecond |
| Bandwidth | DC to 100 kHz |
| ENVIRONMENT AND CONNECTION | |
| Isolation test | 6 kV rms, 50 Hz, 1 minute |
| Operating temperature | -40 to +85 degrees C |
| Connector for suffix -600 | RSD-46607-001 |

03 / SENSING LOOP
Ampere-turns define the effective range.
|
A single conductor pass gives one primary turn. Additional passes multiply the effective ampere-turn value and reduce the conductor current required to reach the same secondary output. |

| 01 | Can CSNK500M-600 replace a standard CSNK500M directly? | The electrical ratio is shared, but suffix -600 uses connector RSD-46607-001. Confirm the harness and pin orientation. |
| 02 | How do additional conductor passes affect CSNK500M-600? | Each aperture pass adds one primary turn. Two passes produce 500 A.t from 250 A of conductor current. |
| 03 | Which burden can CSNK500M-600 drive at 1275 A.t peak? | At a +/-18 V supply, keep the measuring resistance at 5 ohm maximum at the AC peak limit. |
| 04 | Can CSNK500M-600 measure bidirectional DC? | Yes. Secondary-current polarity follows the direction of the primary current, supporting positive and negative DC. |
| 05 | What can alter CSNK500M-600 accuracy after replacement? | Supply imbalance, excessive burden, connector polarity, residual offset and conductor placement should be checked during validation. |
