Please note when placing an order:

1. PS1 is a customized product, please leave a message in the order after taking the photo: the product brand and model + voltage required to supply power. Such as: QA100+9V..

2. In order to avoid that the interface, connection method, and voltage are not in line with your needs, we will not ship orders that are not indicated in the message..

PS1 solves the following problems for QA390.

1. Instead of the linear power supply, plug in the AC power directly, and completely isolate the influence of the AC power, so that the QA390 can be completely changed without shutting down for many years..

2. The transient response is greatly accelerated, and the current margin "makes the electricity flow unimpeded."

3.Because the power supply current margin is larger, the energy is more sufficient, and the transient state is faster.

Output voltage and plug can be customized

1. Although PS1 has only one power output, its output voltage can be customized

2. We can customize and modify the output voltage to 5V, 7V, 9V or even any voltage not higher than 12V. All voltages can provide 2A, even short-term output current of 3A.

3.A parallel output of USB A port is also provided on the machine modified to 5V output.

4. In addition to customizing the voltage, we can also customize the output plug of the DC line, which will be made according to the model of the powered device in your order message, or you can directly contact customer service for consultation

5. By customizing the voltage and plug, PS1 can supply power to any DC input equipment with a voltage not exceeding 12V and a current not exceeding 2A

Design features:

1. It is always 100% isolated from the mains (including the isolation of the global ground loop), completely blocking the interference of the mains noise.

2. Use two sets of 14.8V high-rate batteries with a current output capacity of more than 100A as the ping-pong buffer regeneration output of the power supply.

3.Using 6 LT3045 low noise LD outputs in parallel, the theoretical noise is only 0.33uV

4. Use the preferred large-capacity electrolytic capacitor and copper foil oil-immersed capacitor to compensate for low frequency and high frequency bandwidth

5. Use multiple single-chip computers to intelligently manage battery balance charging and ping-pong buffer switching.

6. Use dozens of low internal resistance and high current MOSs for switching between battery packs and output sources.

7. In order to sound better than QA390 internal battery power supply

8. The switch can select the output source for battery or DC input
