The LEM HAS 100-S/SP50 is a current transducer for electronic measurement of DC, AC or pulsed currents in high power and industrial applications. This transducer provides galvanic isolation between the primary circuit (where the current is measured) and the secondary circuit (where the measurement signal is outputted).

Applications

• Variable Speed Drives: Measuring motor current for control and protection.
• Welding Equipment: Monitoring welding current for precise control of the welding process.
• Uninterruptible Power Supplies (UPS): Monitoring battery charging and discharging currents.
• Switched Mode Power Supplies (SMPS): Measuring input and output currents for power supply control and protection.
• Battery Chargers: Monitoring charging current to optimize charging profiles and prevent overcharging.

Features

• Closed Loop (Compensated) Current Transducer: Provides high accuracy and linearity over a wide current range.
• Galvanic Isolation: Offers high isolation voltage between the primary and secondary circuits, ensuring safety and preventing ground loops.
