Product Specification
| Description | Current Sensors RoHS | Mfr. Part # | LT58-S7/SP8 |
| Model Number | LT58-S7/SP8 |
The LT 58-S7/SP8 is a closed-loop (compensated) current transducer utilizing Hall effect technology for precise electronic measurement of DC, AC, and pulsed currents. It provides galvanic isolation between the primary and secondary circuits, offering excellent accuracy, linearity, low temperature drift, and a wide frequency bandwidth. This transducer is suitable for industrial applications, including AC and DC motor drives, UPS, SMPS, and welding power supplies.
