Product introductionThe minimum voltage difference between the input voltage and theoutput voltage is 4V (when the output is 5V, the input is DC9V-90V,when the output voltage is 12V, the input voltage is DCl6V-90V, whenthe output voltage is 24V, the input voltage is DC16V-90V.(The inputvoltage is DC30-90v) The output voltage is 24V/12V/5Voptional (forother voltages, please contact the customer to order) The maximum output current is 3A (that is, the constant current valueis 3A, when the customized voltage is greater than 12V,the outputcurrent is less than 3A, the power is not recommended to exceed 30W,12V and 5V can reach 3A, 24V is 2A) Typical operatingfrequency: 140KHz High efficiency: up to 95% (the smaller the pressure difference, thehigher the efficiency) Reduce frequency at light load, improve light load efficiency Low standby current Built-in overtemperature,overcurrent, output short circuit protection Built-in soft start Constant voltage constant currentoutput Workingtemperature: industrial grade (-40°C to +85°C) Module volume: 42*30*17mm
Instructions for use1. First connect the connection line between the module and thepower supply, and then poweron. Remember! Remember! (lftheinput terminal is connected with electricity, it is prone to sparking,especially when the input power supply voltage is high, it will evenburn the pads ofthe module) 2. After selecting a suitable power supply, use a multimeterorvoltmeter to measure whether the output voltage ofthe module isconsistent with the voltage required bythe device. 3. Connect electrical equipment or (load) to the output terminal ofthe module.

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.
