LEM LV 25-P is a closed-loop Hall effect voltage transducer for accurate electronic measurement of DC, AC, and pulsed voltages with galvanic separation between the primary and secondary circuits. It is designed for PCB mounting and is suitable for nominal voltage measurement from 10 V to 500 V when used with an external primary resistor R1 selected by the user. The transducer operates from a bipolar ±12 to ±15 V DC supply, delivers a 25 mA secondary nominal current, and is used in industrial applications such as drives, power supplies, UPS systems, renewable energy equipment, and welding power electronics.
