Package Included:
- 1 x Set of Linear Power Supply Module

Note: Other items pictured are not included, for demonstration purposes only.

Precautions:
- The module has no reverse connection and over-voltage protection, please check carefully and then power on the power supply, otherwise the module will be damaged.
- Linear power supply heating is mainly determined by output voltage difference and load current. Please select and use the power supply module reasonably. Generally, a margin of 30% is required.
- It is a step-down module, input voltage needs to be greater than output voltage by more than 1V to stabilize the output.
- The module heats up during use, please increase heat dissipation accessories according to the actual situation. When use with a large load, please appropriately add heat sink.
- When using the module, it is recommended to add 100uF or larger electrolytic capacitors to input and output terminals. Pay attention to the polarity of the positive and negative power supplies when adding capacitance. When using an electrolytic capacitor with a negative power supply, the positive electrode of the capacitor is connected to GND, and the negative electrode of the capacitor is connected to the negative electrode of the module output.
- It is recommended to match our transformer and rectifier filter module to form a precision power supply. If necessary, please contact us.

FAQ:
Q1: Can the module be powered by a single power supply?
A1: No. The module must use dual power supplies to normally output positive and negative voltages.

Q2: Can the module supply power to audio equipment?
A2: This power module is a high-quality power module, designed to power radio frequency equipment and high-end audio equipment.

Q3: Why can't I test the nominal ripple parameters? The measured ripple is relatively large.
A3: First, you need to have a correct measurement method. You can check the power ripple measurement method on the Internet. Secondly, the linear power supply can only suppress the ripple noise of input signal, but not infinitely. If you are using a switching power supply input, the noise is large, then the linear power supply can not play an important role. Therefore, the general linear power input is rectified and filtered through the converter. We have a complete set of transformer rectification and filtering linear power solutions and modules.
