1. Since the module design does not require a common ground at the beginning, it is not possible to add a diode on the board tube, and the output capacitor to prevent damage caused by transient overvoltage, so the user When in use, there may be instantaneous high-voltage pulses, or the use voltage is close to In the case of 35V, it is recommended to add diodes and The output capacitor protects the module. 2. The voltage drop of the module is about 0.3V when the module is unloaded or the load current is extremely small. When the load current When it is greater than 10ma (12V voltage test), the voltage drop will drop significantly and is related to the current small related. 3. Since the module does not need to be grounded, it is superior to modules that need to be grounded. Operating voltage:1.5V-36V Working current: 12V 25 without cooling measures less than equal 15A (15A long-distance running test for 30 minutes) 12V 25 heat sink + air cooling less than equal 30A (30A long-distance running test for 30 minutes) If the theoretical heat dissipation is good, it can be above 50A, but the heat dissipation condition is limited to above 30A No long-distance running test Static current: 0ma (no load state, there will still be current when the load is in sleep state) Positioning method: welding fixed Different batches may have different appearances, but will not affect normal use.
