VAC offers a wide range of current sensors for DC and AC measurements in PCB and panel mount versions.

The principle of the closed-loop current sensor invented by VAC is to have a magnetic probe (i.e., a flux gate probe) as a zero-field detector, which is characterized by maximum accuracy in current detection. The electronic components of VAC current sensors are almost entirely concentrated in specialized ICs.
All VAC sensors can detect high continuous and peak currents in a compact package size. Our current sensors are used in many different customer applications, the most typical are:
- Variable speed drive
- Photovoltaic inverters
- Wind energy converters
- Welding inverters
- Switch-mode power supply
-Ups
VAC current sensors offer certain advantages over commonly used closed-loop sensors that use Hall-effect devices for zero-field detection. Their standout features are:
- Current ratings from 6 A to 1000 A and peak currents up to +2500 A in a compact design
- +5 V power supply type with voltage output. Optional internal or external reference voltage
- Suitable for ± 12 V, ± 15 V, or ± 24 V supply with current output
- Excellent measurement accuracy with minimal DC offset and very low hysteresis
- Negligible output noise
- Very low temperature dependence and long-term drift output signal
- Low rise time, wide frequency range
- Low-cost design
- Low-cost, high-volume production sites
-Market compatible size and nailing
