Product Description

LEM LF 306S Current Transformer is a high precision panel mount device designed for electronic measurement of DC, AC, and pulsed currents. The device provides galvanic isolation between the primary and secondary circuits, ensuring safety in industrial applications.

With a primary current rating of 300A and supply voltages of 12V and 15V, it supports precise current sensing in control and monitoring systems. The 25.5mm bore diameter allows secure conductor passing while maintaining measurement integrity.

The transformer operates reliably over a broad temperature range from -25°C to 70°C, with a protective plastic enclosure rated UL94-V0 for flame retardancy. It offers high noise immunity, low temperature drift, and an optimized response time with minimum operating frequency at 150 kHz, making it suitable for dynamic current measurement environments.

Its compliance with EN 50178:1997, IEC 61010-1, UL, and CE standards guarantees safety and quality for industrial, laboratory, automation, and process control settings. Accurate and stable measurement of DC, AC, and pulsed currents with galvanic isolation.

Supports primary currents up to 300A with 12V and 15V supply voltages. Robust UL94-V0 plastic body construction for durability and safety. Wide operating temperature range from -25°C to 70°C. Minimum operating frequency of 150 kHz for broad frequency bandwidth.

Compact panel-mount design with dimensions 95mm(L) x 110mm(W) x 34.3mm(D). Compliance with major international safety and quality standards.

This LEM LF 306S Current Transformer is ideal for use in industrial automation, electrical measurement, process monitoring, and control systems where precise current sensing and electrical isolation are required.
