This board continuously monitors current draw and instantly triggers an onboard relay when the load exceeds your custom-set threshold, physically cutting power or sending a fault signal before your components can fail.\u003c\/p\u003e\n\u003cp data-path-to-node=\"6\"\u003eEquipped with an onboard potentiometer, you can easily dial in the exact current limit up to 5A. The module typically outputs a digital signal and flips the relay's Normally Open (NO) and Normally Closed (NC) contacts, making it incredibly versatile. You can use it to directly interrupt the power line of a faulting device, or wire the relay to a GPIO pin on an Arduino, ESP32 or STM32 to trigger an interrupt and log the fault in your system.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003e\u003cb data-path-to-node=\"7\" data-index-in-node=\"0\"\u003ePerfect For:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"8\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,0,0\"\u003e\u003cb data-path-to-node=\"8,0,0\" data-index-in-node=\"0\"\u003eIoT Energy Metering:\u003c\/b\u003e Integrate active fault protection into your custom AC and DC energy meters to safeguard both the meter and the connected appliances.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,1,0\"\u003e\u003cb data-path-to-node=\"8,1,0\" data-index-in-node=\"0\"\u003eMotor \u0026amp; Pump Protection:\u003c\/b\u003e Automatically cut power to mechanical loads (like those used in fluid or LPG monitoring systems) if a stall or jam causes a dangerous current spike.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,2,0\"\u003e\u003cb data-path-to-node=\"8,2,0\" data-index-in-node=\"0\"\u003eFailsafe Automation:\u003c\/b\u003e Create standalone safety cutoffs for custom  hardware, power harvesting setups, or prototyping testbenches.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp data-path-to-node=\"9\"\u003e\u003cb data-path-to-node=\"9\" data-index-in-node=\"0\"\u003eTechnical Specifications:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"10\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"10,0,0\"\u003e\u003cb data-path-to-node=\"10,0,0\" data-index-in-node=\"0\"\u003eDetection Range:\u003c\/b\u003e 0 to 5A (AC or DC, depending on the specific sensor IC onboard)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"10,1,0\"\u003e\u003cb data-path-to-node=\"10,1,0\" data-index-in-node=\"0\"\u003eThreshold Adjustment:\u003c\/b\u003e Onboard precision potentiometer\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"10,2,0\"\u003e\u003cb data-path-to-node=\"10,2,0\" data-index-in-node=\"0\"\u003eRelay Capacity:\u003c\/b\u003e 10A @ 250V AC \/ 10A @ 30V DC\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"10,3,0\"\u003e\u003cb data-path-to-node=\"10,3,0\" data-index-in-node=\"0\"\u003eModule Operating Voltage:\u003c\/b\u003e Typically 5V or 12V DC (check your specific variant)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"10,4,0\"\u003e\u003cb data-path-to-node=\"10,4,0\" data-index-in-node=\"0\"\u003eOutputs:\u003c\/b\u003e Relay contacts (NO, NC, COM) and Digital Out (DO) for microcontroller interfacing\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"10,5,0\"\u003e\u003cb data-path-to-node=\"10,5,0\" data-index-in-node=\"0\"\u003eResponse Time:\u003c\/b\u003e Rapid hardware-level switching\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"K-TECHNICS","offers":[{"title":"Default Title","offer_id":42845466001479,"sku":null,"price":650.0,"currency_code":"KES","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/7637\/2039\/files\/5A-overcurrent-protection.webp?v=1780597668","url":"https:\/\/www.ktechnics.com\/products\/5a-ac-dc-overcurrent-protection-sensor-module-with-relay-output","provider":"K-TECHNICS","version":"1.0","type":"link"}
