    ‌LV25-500/SP1 Product Details: Precision Voltage Sensing for Industrial Applications

    ‌

    LV25-500/SP1 ‌Key Features‌
    Closed-loop Hall effect technology ensures complete electrical isolation between primary and secondary circuits, enhancing system safety;
    High measurement accuracy with linearity error below 0.9%, delivering faithful reproduction of voltage signals up to 500 V;
    Wide temperature stability with reliable operation from -25°C to +70°C, suited for demanding industrial environments;
    Robust noise immunity achieved through dual-core magnetic structure and dynamic compensation circuitry, effectively suppressing common-mode interference and external magnetic fields;
    Fast dynamic response under 40 microseconds, enabling precise detection of transient voltage spikes and high-frequency pulses;
    Modular mounting compatibility supporting both PCB surface mounting and panel mounting for seamless integration into control units.

     

    LV25-500/SP1 ‌Technical Specifications‌

    ‌Rated Input Voltage‌: 500 V (DC/AC/Pulse)

    ‌Secondary Rated Output Current‌: 25 mA

    ‌Supply Voltage Range‌: 12 V to 15 V DC (bipolar)

    ‌Bandwidth‌: DC to 100 kHz

    ‌Isolation Voltage‌: 2.5 kV AC (compliant with EN50178 industrial safety standard)

    ‌Temperature Drift‌: ±0.06 mA/°C (within 0–25°C range)

    ‌Operating Temperature Range‌: -25°C to +70°C

    ‌Package Type‌: Compact PCB/panel-mount design, minimizing space requirements

     

    LV25-500/SP1 ‌Applications‌
    Widely deployed in industrial automation and power electronics systems:

    ‌Variable Frequency Drives and Servo Systems‌: Real-time DC bus voltage monitoring to ensure stable motor operation;

    ‌Renewable Energy Inverters‌: High-precision DC voltage acquisition in photovoltaic and wind power systems to maximize energy conversion efficiency;

    ‌Uninterruptible Power Supplies (UPS)‌: Accurate feedback of input/output voltage states to enable intelligent switching and protection logic;

    ‌Welding Power Supplies‌: Delivers stable voltage feedback under high-current transient conditions;

    ‌Rail Transit Traction Systems‌: Used in locomotive and metro propulsion converters, auxiliary converters, and battery charging controls;

    ‌Battery Management Systems (BMS)‌: Monitors high-voltage battery pack voltages to ensure safe and reliable energy storage operation.

     

    ‌Why Choose LV25-500/SP1 This Model‌
    As a global leader in current and voltage sensing, LEM leverages over 40 years of engineering expertise to deliver unmatched reliability in the LV25-500/SP1;
    Its closed-loop Hall architecture delivers superior linearity and thermal stability compared to open-loop alternatives, eliminating the need for periodic recalibration;
    Certified with UL94-V0 flame-retardant housing and 2.5 kV isolation, it meets stringent safety requirements in medical, energy, and rail applications;
    Seamlessly integrates with mainstream industrial controllers, PLCs, and DSP-based systems, reducing development time and simplifying system commissioning;
