Master High Voltage with Precision – LEM LV100-2000/SP10 High-Accuracy Voltage Sensor

In power electronics systems, precise and reliable high-voltage measurement is the cornerstone of safe equipment operation. Whether in your PV inverter, energy storage system, or industrial drive, every millivolt of accuracy matters – it can impact system efficiency or even determine equipment safety.

The LEM LV100-2000/SP10 is built for these challenges. As a flagship product of LEM, the world leader in electrical measurement, this closed-loop Hall-effect voltage sensor is tailormade for demanding industrial and renewable energy applications.

LV100-2000/SP10 Key Specifications

LV100-2000/SP10 Four Core Advantages

1. ±0.3% High Accuracy – Zero Deviation Every Time

Using closedloop Halleffect compensation, the LV100-2000/SP10 delivers industryleading accuracy – ±0.3% at room temperature. With builtin temperature compensation (±0.01%/°C), it outputs true, reliable voltage data regardless of environmental changes.

2. 6 kV Reinforced Isolation – A Solid Safety Barrier

6 kV withstand voltage means industryleading electrical isolation. The primary highvoltage circuit is physically separated from the secondary lowvoltage side, effectively eliminating breakdown risks. For indirect measurement in systems above 10 kV, this sensor represents the highest commitment to circuit safety.

3. < 50 µs Fast Response – Capture Every Dynamic Event

What does < 50 microseconds response time mean? When voltage fluctuations or spikes occur, feedback reaches the controller within milliseconds, allowing the system to react before a fault escalates. Combined with a DC~20 kHz wide bandwidth, even highorder harmonics are captured.

4. Triple Noise Immunity – Accurate Even in Harsh EMI Environments

Builtin EMC filter (meets EN 6100062/4)

Double shielding between primary and secondary

Flameretardant housing (UL94 V0) for harsh industrial use

Whether inside a drive cabinet, highvoltage switchgear, or railway traction system, the signal stays clean and stable.
