5A Mini Smart Electronic Fuse Module DC5–60V Overcurrent Short Circuit Protection Industrial Power Control Circuit Safety Device

Quantity : 1 High-concerned chemical : none is_d : Yes Supply Voltage : DC5-60V Type : Module Brand Name : diymore Origin : Mainland China Condition : New

Features 1. Dual protection featuring precise overcurrent monitoring and rapid short-circuit disconnection; instantly shuts off the output when current abnormalities occur 2. Soft-start with gradual voltage ramp-up and a built-in surge suppression mechanism effectively prevent damage to the system caused by inrush current 3. Real-time monitoring of dual thresholds for OVP (overvoltage) and UVP (undervoltage); output is immediately cut off once the input voltage exceeds the limits 4. The protection mechanism is triggered when the module’s temperature rise exceeds the threshold, preventing performance degradation or component damage caused by sustained overheating 5. Real-time output signals are generated when a protection event occurs, enabling rapid fault source localization and more efficient operations and maintenance Differences from Traditional Fuses Traditional fuses: Rely on a metal wire that melts due to heat; they are single-use and must be manually replaced after a fault; they have a slow response time and provide only overcurrent protection. Electronic fuses: Rely on semiconductor chips and MOSFETs for protection; there is no physical melting; they can be automatically or manually restored to once the fault is resolved; they are considered recoverable protective devices. Parameter Operating Voltage: DC 5–60 V Current Limiting Range: 5 A Quiescent Current: 1.38 mA (active); 21 μA (off/sleep) Operating Temperature: -20°C to +60°C Protection Functions: Overcurrent protection, fast short-circuit protection, 4.5V undervoltage protection, 60V overvoltage protection, and chip overheating protection Precautions 1. The input voltage range is DC 5–60V; the maximum transient voltage must not exceed 65V, as exceeding this limit will permanently damage the module. 2. The power supply’s output capacity must exceed the module’s set current limit; if the power supply’s current is too low, it will be clamped during a short circuit, causing the module’s protection functions to malfunction. 3. The output voltage follows the input voltage; it does not step up or step down the voltage. 4. Do not set the current limit exactly equal to the load’s rated current; it must be greater than the normal operating current, otherwise the inrush current upon power-up may trigger a false trip. 5. Do not reverse the input and output connections; connect “IN” to the power supply and “OUT” to the load. The module does not support reverse current injection (output voltage higher than input voltage). For inductive loads (relays, motors), it is recommended to connect a Schottky diode in parallel across the output terminals to absorb reverse negative voltage spikes and prevent damage to the chip. 6. The operating ambient temperature range is 20°C to +60°C. Do not operate at full load for extended periods in high-temperature, enclosed environments. 7. Do not connect multiple modules in parallel to increase current capacity, as current will not be distributed evenly among the modules, causing one of them to trigger protection first. 8. For DC circuits only; AC input is prohibited. Package include Electronic Fuse Module *1
