Normally Open Current Transformer Adjustable AC SZC23-NO-AL-CH Senser Swtich

 
Product Features
1. Self powered, without the need for external power supply.
2. The operating current of 0.2A-30A AC can be adjusted through a potentiometer.
3. The LED status indicator light can conveniently and intuitively indicate the working status of the switch.
4. High power MOS transistor contactless electronic switch.
5. The switch has no limit on the number of making and breaking times, and is designed with a through core structure, with isolation and withstand voltage up to 2000V.
6. If the hysteresis is less than 1%, it can be used under strong magnetic field conditions.
 
Product Introduction
SZC23-NONC-AL-CH AC Current Sensing Switch is designed and produced to solve AC current monitoring. It uses the principle of mutual inductance to induce AC through core current, isolate AC current, output a switch signal, and directly control various automated industrial control equipment, flashing lights, buzzers, relays, microcontrollers, or other power load devices. Compared with traditional transformers, thermal protectors, and other devices, The use of this device can not only achieve more accurate and timely control effects.
 
operational principle
Based on electromagnetic induction, induced current is generated when the current in the circuit changes. This series of AC current induction switches uses an inductance coil to induce the amplitude of AC current, determine whether it exceeds the preset current action value, and change the output state of a solid-state switch, similar to the function of a mechanical switch.
 
Typical Applications
AC current monitoring and detection.
Current overload protection.
Used as an electronic switch for automatic control systems.
Equipment linkage, etc.

matters needing attention
Before making electrical connections, all power sources in the circuit should be disconnected to avoid electric shock accidents. The meanings represented by different indicator lights:
For NO normally open type, a green light indicates that the switch is open, there is current flowing through the switch, but it has not reached the starting value, and the contact is open; The red light indicates that the switch is closed, the current reaches the starting value, and the contacts are closed, indicating that the switch is in working condition.
 
Installation and usage instructions:
1. Disconnect all power sources in the circuit and fix the AC current sensing switch in a suitable position through the mounting hole on the base. If tied with a rope, make sure to tie the rope firmly. If installed with screws, make sure to tighten each screw.
2. Connect the core current circuit, disconnect the tested circuit first, let the tested circuit pass through the induction hole of the current switch, and reconnect the circuit:
3. Connect the load line and note that the maximum AC load of this series of current switches cannot exceed 0 5A0240VAC/DC.
4. After checking the installation wiring, turn on the power switch and set the upper and lower limits of the induction switch current according to the user's own needs
