Dc 5-60v 5a Intelligent Semiconductor Electronic Fuse Module Battery Motor Power Supply Short Circuit Protection Switch Board

Product Features:Style A1. If the current exceeds the set value, the output will be quickly cut off, effectively protecting the power supply and backend load from damage2. When connecting large capacitive loads, power on smoothly to effectively suppress surge peaks and avoid system impact3. Dual monitoring of overvoltage (OVP) and undervoltage (UVP), with immediate cut-off in case of abnormal voltage4. The module is equipped with a built-in temperature control mechanism, which automatically protects against temperature exceeding limits, ensuring continuous and stable operation5. Output an alarm signal when there is a malfunction, facilitating the linkage response of the upper computer and quickly troubleshooting and locating problemsProduct IntroductionElectronic fuse module, also known as electronic fuse or solid-state insurance module, is a circuit board with a dedicated power protection chip as its core, used to replace traditional glass tube and ceramic disposable fuses for DC power circuit protection.Difference from traditional fusesTraditional fuses: rely on metal wires to generate heat and melt, burn out in one go, and must be manually replaced after failure. They have slow response and can only provide overcurrent protection.Electronic fuse: It relies on semiconductor chips and MOS transistors for protection, without physical melting. After the fault is resolved, it can be automatically/manually restored to use and belongs to recoverable protection devices.Product SpecificationsWorking voltage: DC 5-60VCurrent limiting range: 5ARecovery Type: Automatic RecoveryIndicator light status: Blue light on, working normally, red light on, short circuit protection, red light on, blue light flashing regularly, output overcurrent protection in progressStatic power consumption: working 2mA; turning off sleep 21 μ AWorking temperature -20 ℃~+60 ℃Protection functions: overcurrent protection, short circuit quick protection, 4.5V undervoltage protection. 60V overvoltage protection, chip overheating protectionPrecautions1. The input voltage range is DC 5-60V, and the transient maximum does not exceed 65V. Exceeding this range will permanently damage the module.2. The output capacity of the power supply should be greater than the current limit set by the module; If the current of the power supply itself is very low, it will be clamped by the power supply during a short circuit, and the module protection function will be abnormal.3. The output voltage follows the input voltage and does not increase or decrease.4. When selecting the current limit value, do not set it exactly equal to the rated current of the load. It should be greater than the normal operating current, otherwise the surge during power on may cause false protection tripping.5. Do not connect the input and output in reverse. Connect IN to the power supply and OUT to the load; Does not support reverse current injection (output voltage higher than input). It is recommended to parallel Schottky diodes at the output end of inductive loads (relays, motors) to absorb reverse negative pressure spikes and prevent chip damage.6. The working environment temperature should be between 20 ℃ and+60 ℃. Do not work at full load for a long time in a high-temperature sealed environment.7. Multiple modules cannot be connected in parallel for current expansion, as uneven current flow between modules can result in one module being prioritized for protection.8. Only used for DC circuits, AC input is prohibited.Packing ListElectronic fuse module * 1Product Features:Style B1. With the dual support of precise overcurrent monitoring and rapid short-circuit cutting, the output is instantly turned off when the current is abnormal2. Soft start slow boost, built-in surge suppression mechanism, effectively avoiding the damage of surge current to the system3. OVP overvoltage and UVP undervoltage dual threshold real-time monitoring, and once the input voltage exceeds the limit, the output is immediately cut off4. If the temperature rise of the module exceeds the standard, the protection mechanism will be triggered to avoid performance degradation or device damage caused by continuous overheating5.
