LEM LV 25-P-1 Voltage Transducer

The LEM LV 25-P-1 is a high-accuracy voltage sensor. It safely measures AC, DC, and pulsed voltages using total electrical isolation.

Key Specifications

Voltage Measuring Range: 10 to 500 V
Secondary Nominal RMS Current: 25 mA
Supply Voltage: ± 12 V to ± 15 V DC
Accuracy: ± 0.8% to ± 0.9% of nominal voltage
Isolation Voltage: Up to 4.1 kV
Operating Temperature Range: -25°C to +70°C (or up to +85°C in some versions)

Flexible Voltage Ranges: It natively measures a small primary current of 10mA. By changing a single external resistor, you can set it up to measure voltages anywhere from 10V up to 500V.
Compact PCB Mounting: Designed with pins to solder directly onto your circuit board. It takes up very little space, making it perfect for compact industrial layouts.
Smart Fluxgate Tech: Uses advanced closed-loop technology. It quickly balances out internal magnetic fields to deliver highly stable, lightning-fast voltage readings.
Safety First: Keeps your dangerous high-voltage lines completely separate from your delicate low-voltage microcontrollers. This protects your electronics and the people using them.
