SZC23-NO-AL-CH Normal Open AC Current Sensing Switch Adjustable AC 0.2-30A for AC Current Monitoring

SZC23-NO-AL-CH Normal Open AC Current Sensing Switch Adjustable AC 0.2-30A for AC Current Monitoring

Description:
The AC current sensing switch is designed and manufactured to solve the AC current monitoring. It uses the principle of mutual inductance to sense the AC straight-through current, isolate the AC current, and output a normally open or normally closed switching signal to directly control various automation industrial equipment, such as flash, buzzer, relay, MCU and other power load equipment. Compared with traditional mutual inductors, thermal protectors and other devices, using this device can not only get more accurate and more timely control, but can also greatly simplify the design and reduce costs.

With high precision, stable performance and long service life, it is an ideal choice for automated industrial control equipment and power monitoring.

It can be widely used in substations, frequency conversion speed control devices, inverter devices, electrolytic plating, electric locomotives, street lamp monitoring, coal mines and other automation industries that require current monitoring.

Features:
- Self-powered: no external power supply required.
- Adjust action current AC 0.2-30A with a potentiometer.
- LED indicator can conveniently and intuitively indicate the working status of the switch.
- High-power MOSFET contactless electronic switch.
- The switch has no limit on the number of opening and closing, and the reaction speed reaches the ms level.
- Straight-through structure design, isolation withstand voltage up to 2000V.
- Hysteresis is less than 1% and it can be used under strong magnetic conditions.
- The outer casing is made of self-extinguishing material ABS.
- AC DC load that can be connected to the switch is rated at 0.5A at 240VAC/DC.
