Introduction to parameters:
Operating voltage: 1.5V – 36V
Working current:
12V 25°C without cooling measures ≤15A (15A long-distance running test for 30 minutes)
12V 25℃ heat sink + air cooling ≤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
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.
The potential is obvious, it can be directly connected into the circuit like a diode, and the static working voltage
The flow is 0, but there are also disadvantages. If your product is sensitive to the following
sense, then it is not applicable to this module
a) It is sensitive to the fluctuation of the output voltage. When the module is working, there is a certain The time voltage drop is above 0.3V, generally not exceeding 0.7V, this time Very short, accounting for about 2% of the entire working time, that is to say For 100S, the pressure drop will be greater than 0.3S for about 2S, but every The time when the second

El paquete ha llegado, todo está bien. Lo probaré. Hasta 100 caracteres.
Probé dos diodos OR-ing, la fuente de alimentación cambia automáticamente entre 19v y 12v para estabilizar la potencia. La fuente de alimentación prioritaria funciona en estos diodos. Compré estos como reemplazos para diodos Schottky porque la alta corriente y Schottky se calientan mucho, estos diodos ideales apenas se calientan.
