Working Principle: Based on electromagnetic induction, when\nthe current in the circuit changes, an induced current is generated.This\nseries of AC current induction switch uses the inductance coil to induce the\namplitude of the AC current to determine whether it exceeds the preset current\naction value to change the output state of a solid state switch, similar to\nthe function of a mechanical switch. Read more Precautions: Before making\nelectrical connections, disconnect all power supplies in the circuit to avoid\nelectric shock accidents.The meaning of different indicators: For NO normally\nopen type, the green light indicates that the switch is off, current flows\nthrough the switch, but the starting value is not reached, and the contact is\noff; The red light indicates that the switch is closed, the current reaches\nthe starting value, and the contact is closed, the switch is in working\ncondition. Read more SZC23 series AC current sensing switch is designed and\nmanufactured to solve the AC current monitoring. It uses the principle of\nmutual inductance to sense the AC straight-through current, isolate the AC\ncurrent, and output a normally open or normally closed switching signal to\ndirectly control various automation industrial equipment, such as flash,\nbuzzer, relay, single-chip or other power load equipment. Compared with\ntraditional mutual inductors, thermal protectors and other devices, using this\ndevice can not only get more accurate and more timely control, but can also\ngreatly simplify the design and reduce costs.Suitable for AC current\nmeasurement and monitoring, AC motor overload protection, electronic switch of\nautomatic control system and so on.

If you use screws to install, make sure to tighten each\nscrew.Connect the core current loop, first disconnect the tested circuit, let\nthe tested circuit pass through the induction hole of the current switch, and\nreconnect the circuit; Connect the load circuit, note that the maximum AC load\nof this series of current switches cannot exceed 0.5A@240V AC\/DC.After\nchecking that the installation connection is correct, turn on the power switch\nand set the upper and lower limits of the induction switch current according\nto the user's needs: NO normally open type If the red light is on at this\ntime, adjust the potentiometer to the H direction until the green light is on\nand stop, then adjust it to the L direction, and then stop when the red light\nis on. If the green light is on at this time, turn the adjustable\npotentiometer to the L direction until the red light just lights up and stop.\nThe alternating point of the red and green lights is the current value of the\ncurrent through the heart. Common Problems and Solutions: After the\npenetration current reaches the set value, the load circuit is not\nautomatically connected: Solution: Check whether the wiring of the output\nsignal is loose and whether the load circuit wiring is loose. If an AC\ncontactor is used, check whether the wiring of the AC contactor is loose and\nwhether the AC contactor is damaged.After the AC feedthrough current is\napplied, the two LED indicators are off: Solution: Check whether the input AC\ncurrent is normal and whether the wiring is loose.After the AC feedthrough\ncurrent is applied, both LED indicators are on: Solution: The input AC\nfeedthrough current is too large, pay attention to the feedthrough current not\ntoo large, if it exceeds the allowable range of the current sensor switch, the\nswitch will be damaged.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003eSelf-powered, no external power supply required.\u003c\/li\u003e\n \u003cli\u003eAction current 0.2-30A AC, adjustable with a potentiometer.\u003c\/li\u003e\n \u003cli\u003eLED indicator can conveniently and intuitively indicate the working status of the switch.\u003c\/li\u003e\n \u003cli\u003eHigh-power MOS tube contactless electronic switch.\u003c\/li\u003e\n \u003cli\u003eThe switch has no limit on the number of opening and closing, and the reaction speed reaches the ms level.\u003c\/li\u003e\n \u003c\/ul\u003e\n\n\n\n\n","published_at":"2021-09-12T00:57:58+10:00","created_at":"2021-09-12T00:57:58+10:00","vendor":"Hilitand","type":"Current Monitoring Relays","tags":["cocoon"],"price":14700,"price_min":14700,"price_max":14700,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":41111082270875,"title":"Default Title","option1":"Default Title","option2":null,"option3":null,"sku":"B07N1P6TWL","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"Current Sensing Switch, Normally Open Current Sensing Relay Adjustable AC 0.2A -30A (SZC23-NO-AL-CH Model)","public_title":null,"options":["Default Title"],"price":14700,"weight":59,"compare_at_price":null,"inventory_management":null,"barcode":"Hilitand8k3b14u2na","requires_selling_plan":false,"selling_plan_allocations":[]}],"images":["\/\/leoforward.com\/cdn\/shop\/products\/B07N1P6TWL.jpg?v=1651434418","\/\/leoforward.com\/cdn\/shop\/products\/514g5zlgpdL.jpg?v=1631430991","\/\/leoforward.com\/cdn\/shop\/products\/6130RU8rJVL.jpg?v=1631430991","\/\/leoforward.com\/cdn\/shop\/products\/7119fKkQSDL_795bb5dd-15bf-4a5c-bc6e-e7bbe1843f83.jpg?v=1631430991","\/\/leoforward.com\/cdn\/shop\/products\/61SB6SYB0YL_5c302dfd-5bc4-4a25-ae01-e5fa10bc5b9a.jpg?v=1631430991","\/\/leoforward.com\/cdn\/shop\/products\/61Ai3Ck1CtL_0015afa3-5949-49e0-b9f6-e4777b1c70cb.jpg?v=1631430991","\/\/leoforward.com\/cdn\/shop\/products\/51Mz_6GOMnL_911b83af-97f8-4835-b12f-3672796a789c.jpg?v=1631430991","\/\/leoforward.com\/cdn\/shop\/products\/51PIkAGpaTL_22d7645b-1ff2-4090-877d-5274a357912c.jpg?v=1631430991","\/\/leoforward.com\/cdn\/shop\/products\/613sCq2v41L.jpg?v=1631430991"],"featured_image":"\/\/leoforward.com\/cdn\/shop\/products\/B07N1P6TWL.jpg?v=1651434418","options":["Title"],"media":[{"alt":"Current Sensing Switch, Normally Open Current Sensing Relay Adjustable AC 0.2A -30A (SZC23-NO-AL-CH Model) -
