KV_84853A ±9V High Power Linear Power Module Ultra-low Ripple Positive and Negative Dual Power Supply Module AC DC

Description:
- This module uses ultra-high performance LDO chips to provide a complete solution for high-precision power supply simulation applications. This module is suitable for ripple sensitive application scenarios, such as audio amplifiers, operational amplifiers, ADCs, DACs, and other high-performance analog circuits. This module supports multiple voltage outputs (±5V, ±9V, ±12V, ±15V optional), and can be switched by welding the corresponding jump point. The output current can reach ±3A, and its extremely low ripple makes it suitable as a post voltage regulator for switching power supplies, further optimizing the quality of the output power supply.

Precaution:
- The module belongs to the step-down type, and the input voltage needs to be greater than the output 1V to achieve stable output.
- When working at high power for a long time, it is recommended to control the input and output pressure difference within 3V, or use a cooling fan to increase heat dissipation.
- Heating is an inevitable characteristic of LDO linear power supply. When outputting full load current or large current, please control the input and output pressure difference and heat dissipation.
- The heating of the module is mainly determined by the input and output voltage difference and the load current. Please choose and use the power module reasonably, and generally reserve a certain margin.

FAQ:
Q: Why can't the output of the module reach ±12V when selecting a ±12V output for the skip point and ±11V for module input power supply?
A: The module belongs to the step-down type, and the input voltage needs to be greater than the output 1V to achieve stable output.

Q: Can positive and negative voltages simultaneously output maximum current?
A: Sure, provided that the power of the input voltage is sufficient.

Q: Why does the maximum output power of the module not reach the nominal value when I use it?
A: To achieve high output power, the input power of the module must be greater than the output power.

Q: Can the module power audio devices?
A: This power module is a high-quality power module that can provide power for RF devices and high-end audio devices.

Q: Why can't the nominal ripple parameters be tested?
A: Firstly, a correct measurement method is required, such as searching for Power Ripple Measurement Method. Secondly, the difference in input and output voltage, as well as the carrying current, also have a certain impact on the output ripple.
