Product Specification
| Description | Current Sensors RoHS | Mfr. Part # | LZSR150-P/SP1 |
| Model Number | LZSR150-P/SP1 |
The LZSR 150-P/SP1 is a closed-loop, multi-range current transducer designed for the electronic measurement of DC, AC, and pulsed currents. It provides galvanic separation between the primary and secondary circuits, featuring a voltage output and unipolar supply voltage. Its advantages include very low offset drift and excellent dv/dt immunity, making it suitable for demanding industrial applications such as AC variable speed and servo motor drives, battery-supplied systems, Uninterruptible Power Supplies (UPS), Switched Mode Power Supplies (SMPS), welding power supplies, and solar inverters. The transducer offers a higher measuring range and is built to meet various international standards.
