LA 125-P/SP4 Description

Short technical summary and product information.

The LEM LA 125-P/SP4 is a closed-loop Hall effect current sensor capable of measuring DC, AC, and pulsed currents up to a nominal 125A. It provides reinforced galvanic isolation between primary and secondary circuits.

 

This sensor features a high accuracy of ±0.5% and a linearity of ±0.1%, with a fast response time of 0.5µs. It operates over a wide frequency range from DC to 150kHz and supports bidirectional current measurement. The operating voltage range is ±12V to ±15V, and it functions reliably within an operating temperature range of -40°C to 85°C.

 

Designed for through-hole mounting, the LA 125-P/SP4 comes in a module, single pass-through package. Its robust construction and precise measurement capabilities make it suitable for various industrial applications requiring accurate current monitoring.

 

Compliance includes RoHS3 status, MSL 1 Unlimited, and REACH Unaffected, though these are currently unverified.
