Feature:1. Numerical control adjustment, precise and fast, can be boosted or stepped down, output voltage 0.5‑30V arbitrarily adjusted, limit current 0‑4A arbitrarily adjusted.2. Input terminal anti reverse protection, reverse connection will not burn, the output ripple is small, with π‑type filtering.3. Anti backflow at the output terminal, no need to add an anti‑backflow diode when charging the battery4. Possess a variety of software protection mechanisms, the protection threshold is adjustable, thicker heat sink, more stable module performance5. After the module's operating parameters exceed the protection threshold, the output is automatically turned off.Specification:Item Type: Power ModuleMaterial: ABSInput Voltage: DC 5.5-30V/6.0-36VOutput Voltage: DC 0.5-30V（4KX)/DC 0.6-36V(5KX）Output Current: 0-4A/0-5AOutput Power: 35W（4KX)/80W(5KX）Voltage Display Resolution: 0.01VCurrent Display Resolution: 0.001AConversion Efficiency: About 88%Purpose: Change the VoltageCompatible: For Electronic Equipment, Mechanical Engineering, Motors.Package List:1 x Power ModuleNote:In order to ensure the accuracy of calibration, calibration voltage‑voltage above 12V can start calibration; calibration current‑current above 1A can start calibration.1. Module input IN‑ must not be short‑circuited with output OUT‑, otherwise the constant current function will fail.2. Please make sure that the power of the power supply is always greater than the power required by the output load!3. If the module wants to output at full load, the input voltage must be above 8V. When the input voltage is 5V, the output power is about 15W. The maximum current value of the module is 4A, provided that it is limited by the maximum output power, for example, when the output is 17V, the current should not be greater than 2A.4. When using this module over 3A, 35W, please strengthen heat dissipation5. The module has an input under‑voltage protection function, the default is about 4.8V (can be set), when the value is lower than this value, it will automatically disconnect the output (note that the voltage at the module port is lower than the under‑voltage protection threshold, when the input current is compared When it is large, don't ignore the partial voltage on the input wire).
