Precautions:
(1) The module has no over-voltage protection, so please check and compare the power supply carefully before powering on, otherwise the module will be damaged.
(2) The heating of the linear power supply is mainly determined by the output voltage difference and the load current. Please select and use the power supply module reasonably. Generally, a 30% margin needs to be reserved.
(3) The module is a step-down module, and the input voltage needs to be more than 1V above the output to ensure stable output.
(4) The module will heat up during use. Buyers are requested to enhance heat dissipation according to the actual situation. When carrying a large load, the user can appropriately add more heat sink.
(5) When using the module, it is recommended to add 100uF or larger electrolytic capacitors to the input and output terminals.
(6) It is recommended to use our transformer and rectifier filter module to form a precision power supply.

FAQ:
Q1: Can the module power audio equipment?
A1: Yes. It is a high-quality power module designed to power RF equipment and high-end audio equipment.

Q2: Can the four outputs of the module be connected in parallel?
A2: When the four output voltages are the same, the four outputs can be connected in parallel, and the maximum output current is 2000mA. It is not recommended to use the maximum current, and a certain margin needs to be left.

Q3: Why can't the nominal ripple parameter be tested?
A3: First of all, it should be tested in a correct way and you can search the power supply ripple measurement method on the Internet. Secondly, the linear power supply can only suppress the ripple noise of the input signal, but it is not unlimited. If the switching power supply input is used and the noise is large, the linear power supply will not play a major role. Therefore, the general linear power input is rectified and filtered through a transformer. Our shop has a complete set of transformer rectification filter linear power supply solutions and modules.
