Frequently Asked Questions

What is the operating supply voltage range for the LEM HTFS transducer?

The transducer requires a single +5V DC supply, with a specified operating range from 4.75V to 5.25V. It is critical to stay within this range to ensure specified accuracy and proper ratiometric output behavior.

How do I interpret the voltage output signal from this current sensor?

The HTFS provides a ratiometric voltage output. At zero primary current, the output is typically at half the supply voltage (e.g., 2.5V with a 5V supply). The output voltage will increase or decrease linearly from this midpoint proportionally to the measured current, up to the full-scale range.

What does 'galvanic isolation' mean for this sensor, and why is it important?

Galvanic isolation means there is no direct electrical connection between the high-current primary circuit being measured and the low-voltage secondary output circuit. This protects sensitive control electronics from high-voltage transients, ground loops, and faults, enhancing system safety and signal integrity.

Can this sensor measure both AC and DC currents accurately?

Yes, the Hall effect-based closed-loop design of the LEM HTFS transducer allows for accurate measurement of DC, AC, and complex pulsed or mixed current waveforms within its ±300A range and up to its specified bandwidth, which is defined by the fast 7µs response time.

How should I mount and secure the transducer on my PCB?

The module is designed for PCB mounting and is secured using M3 nuts and screws through its mounting holes. Ensure proper mechanical fixation to prevent vibration-related issues and maintain the specified air gap/creepage distances for the high-voltage isolation.
