Current Sensing Relay AC Current Sensing Switch 0-30A Normally Open Current Sensor Monitoring Relay (M3050) — Open-Box, 5% Off

Multi-Purpose: M-3050 AC current sensing switch is specially designed and manufactured to solve AC current monitoring. It uses the principle of mutual inductance to sense AC direct current, isolate the AC current, output normally open or normally closed switch signals, and directly control various automated industrial equipment, such as flash lamps, buzzers, relays, microcontrollers or other power load equipment.

Upgrade: Compared with traditional transformers, thermal protectors and other devices, using this device can not only get more accurate and timely control, but also greatly simplify the design and reduce costs. Self-powered, no external power supply required. Input through current: 0-30A AC Rated load: 0.3A@240V AC/DC.

High Performance: The switch has no limit on the number of times of opening and closing, and the response speed reaches the millisecond level. The hysteresis is less than 1% and can be used under strong magnetic conditions. Through structure design, isolation withstand voltage up to 2000V.

LED Indication: The action current is 0-30A AC, which can be adjusted by the potentiometer. The LED indicator light can easily and intuitively indicate the working status of the switch.

ABS material: High-power MOS tube non-contact electronic switch is used, and the shell is made of self-extinguishing material ABS, which is heat-resistant, acid-alkali-resistant, high impact strength and stable in performance.

The M series AC current sensing switch is designed and produced to solve the monitoring of AC current. It isolates the AC current through the induction of the AC through-core current, outputs a normally open or normally closed switch signal, and directly controls various automation and automatic industrial control. devices, flashers, buzzers, relays, microcontrollers, or other electrical load devices. Compared with traditional transformers, thermal protectors and other devices, the use of this device can not only obtain more accurate and timely control effects, but also greatly simplify the design, reduce costs, and improve the overall competitiveness of the product. It has the advantages of high precision, stable performance and long service life, and is an ideal choice for automatic industrial control equipment and power monitoring. It has been widely used in automation industries such as substations, frequency conversion speed control devices, inverter devices, electrolytic plating, and electric locomotives.
