Featuring adjustable sensitivity, rapid sub-50ms response, and robust relay switching capable of handling up to 10A loads, it’s ideal for intelligent motor protection, overcurrent detection, and automation projects. Its durable metal build and fixed mounting holes make it a reliable choice for professional-grade electrical control systems. ## Description Parameter: Product Name: 0-5A AC Current Detection Sensor Module Output mode: relay switching output. Relay load: AC 250V 10A Max , DC 30V 10A Max. Operating voltage: DC 5V / 12V / 24V ± 0.2V. (Select the corresponding version of the product according to your needs). Working current: <10mA. Response time: <50ms. Induction sensitivity: Potentiometer is adjustable. The overcurrent signal setting is adjustable and the resolution is set to 0.3A. The main chip: op amp, transformer. The current detection resolution can be changed by the resistance parameter setting. With fixed mounting holes. The main chip: op amp, transformer. Module size: 48x40x30mm (length x width x height). Working temperature: -10 - +50 °C. Working humidity: 5-95% RH. Application: Intelligent trolley motor over-current detection, motor stall protection current detection, short-circuit protection detection, etc. Package Included: 1pcs NOYITO 0-5A AC Current Detection Sensor Module Review: It serves the pupose - Working perfectly, tried to use it to detect the AC blower for boost fans on/off. The hole for current detection is too small Review: The five volt power connections that I got are cheap, attaching poorly, than pictured. - The five volt power supply connector shown product page shows a little white plastic box on the circuit board, to guide the two little female wires inside a white plastic plug into position. The product I received did not have that little white plastic box - and the two wire power wire did not have that white plastic plug. It was just two pins sticking out of the board, for ground and 5 volt VCC, and two even more tiny little female plugs, one on the end of each wire. They do not make a firm connection. One of the wires attached enough to not simply fall out if the board was held upside down, and the wire did not even hold that well. Looks like they saved a couple more cents on the product, since taking the image shown on the product page. I've jury rigged a tighter connection by fattening the two pins sticking up from the board with a bit of solder, and glued the wires even tinier two little female plugs holding the power wires onto the board. I don't yet know if that will work ... it might. This is on the 5 volt variant. I will be using this to control a 5 volt Noctua fan (from my ample supply of computer parts) to cool the evaporator coils on a Midea WHS-65LB1 Compact Refrigerator when the condenser motor is running, without blowing room temperature air over the same area that should be cooler than room temperature when the condenser motor is not running. I want the fan to come on only when this board senses the 1 amp 120 volt A/C on the hot wire side of the power feeding the Midea's condenser motor. The evaporator coils are hidden in the left side (looking from the front) of that model refrigerator. When the condenser motor is running, one can feel that left side wall of this refrigerator get perhaps 20F degrees hotter than room temperature, which is how I know that the (otherwise well hidden) evaporator coils are hidden in that wall. The fan will be blowing on a large rectangular passive heat sink that I will be gluing directly to the bare aluminum of that wall, with thermally conductive glue, after first scraping off the thermally resistant paint in that location. The cooling cycle should be more efficient, cooling quicker, with this fan blowing there, and the refrigerator should not be having (warmer than inside the refrigerator) air blowing on its left wall when the motor is off. ## Features - Current detection range: AC 0-5A. - Operating voltage: DC 5V / 12V / 24V ± 0.2V.
