Product Information


Specification
Brand : Cunyuer
BulletPoint1 : SELF-POWERED WORKING: Eliminates external power requirements while detecting AC currents. Provides circuit protection in industrial environments. Hysteresis is less than 1% and can be used under strong magnetic conditions
BulletPoint2 : ADJUSTABLE CURRENT SETTING: Features potentiometer for precise 0.2-30A adjustment. Integrated current sensing relay with LED indicator light can conveniently and intuitively indicate the working status of the switch in the circuit status
BulletPoint3 : CONTACTLESS ELECTRONIC DESIGN: Utilizes high-power MOS tube current sensor technology to prevent mechanical touch wear. Ensures stable switching performance of sensor switch for long-term industrial use
BulletPoint4 : SPECIFICATION: The maximum rated load is 0.5A, 240V AC/DC, and the accuracy is 1%. The relay tester works in an environment ranging from -20 to 60 ℃. Straight through structural design, with insulation withstand voltage up to 2000V
BulletPoint5 : INDUSTRIAL APPLICATION: Designed for AC pressure switch integration in monitoring systems and protection circuits. The current sensing switch structure can withstand harsh electrical environments

ProductDescription : SZC23 series 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, single-chip or 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.
