modname=ckeditorIntroduction 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
The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.
In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.
All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.
This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
