Description

The LV 25-1200 is a high-precision voltage transducer developed by LEM for non-intrusive voltage monitoring in high-voltage AC/DC systems. Based on closed-loop Hall effect technology, this module ensures reliable voltage measurement up to ±1800 V with full galvanic isolation between primary and secondary circuits. Its compact design integrates both the primary resistor and sensing electronics, offering a robust solution for electrical isolation in demanding industrial and power conversion environments.

Features

Closed-loop Hall effect sensing for accurate voltage detection
Nominal voltage input of 1200 V RMS with ±1800 V measuring range
Galvanic isolation up to 4.1 kV (1 min AC test), 12 kV impulse withstand
High linearity (≤0.2%) and low offset drift over temperature
Reinforced insulation according to EN 50178 and UL 508
Low power consumption: nominal secondary current 25 mA
Supports ±12 to ±15 V supply operation

Applications

AC motor drives and inverter systems
DC motor controllers and static converters
Uninterruptible power supplies (UPS)
High-voltage welding equipment
Industrial voltage monitoring and diagnostics

Mechanical Characteristics

The LV 25-1200 is constructed in a flame-retardant insulating housing rated to UL 94-V0. The module mounts via four 4.2 mm holes using M4 screws and requires a dedicated holder to ensure proper mechanical stability. Both primary and secondary terminals are designed with Faston 6.3 × 0.8 mm connectors, simplifying integration into standard power busbars. The total mass of the device is approximately 60 grams, and general mechanical tolerances are maintained within ±0.3 mm. The transducer’s dimensions are optimized for PCB or chassis mounting with minimal space requirements.
