Description
Product Overview
The FTVOGUE AC Current Sensing Switch NO is a high‑performance, self‑powered device designed to detect alternating current ranging from 0.5 A to 50 A without the need for an external power supply. Its compact dimensions of 2.56 × 0.98 × 1.89 inches and lightweight construction (0.35 oz) make it easy to install in tight panels. The switch features a normally‑open (NO) contact configuration, a rated load of 0.3 A at 240 VAC, and a fast millisecond‑level response time, ensuring rapid and reliable actuation. An integrated LED indicator provides immediate visual feedback on the switch status, simplifying troubleshooting and system monitoring.

FAQ
What does “self‑powered” mean for this switch?
Self‑powered means the switch harvests the energy from the line it monitors, so no separate power source or wiring is required to operate the sensing circuitry.
Can the threshold be adjusted while the device is in service?
Yes, the threshold is adjustable from 0.5 A to 50 A using the built‑in potentiometer, allowing on‑site tuning without removing the unit.
Is the LED indicator suitable for use in noisy industrial environments?
The LED provides a clear visual cue that can be seen even in bright or noisy settings, and it can be linked to external monitoring systems for remote status alerts.
What is the maximum load the switch can handle?
The switch is rated for a load of 0.3 A at 240 VAC, making it ideal for control and signaling applications rather than direct power switching.
How does the device ensure long‑term reliability?
By using a contactless MOS‑tube design, the switch eliminates mechanical wear, and the solid‑state components are rated for unlimited cycling, ensuring consistent performance over the product’s lifespan.
