1. Based on the required working voltage, first adjust the " coarse adjustment" knob, then gradually adjust the " fine adjustment" knob, ensuring proper coordination. For instance, if a 12V working voltage is necessary, set the " coarse adjustment" knob to the 19V position, and then adjust the " fine adjustment" knob to 12V. The " coarse adjustment" knob should not be set to the 10V position. Otherwise, the output voltage will not reach 12V.
2. Adjust to the required working voltage before connecting the load. Aviation power supply
3. During the entire application process of the AC adjustable voltage power supply, if it is necessary to switch to the "粗调" (粗调) setting, first disconnect the load. Wait until the output voltage is adjusted to the required value before reconnecting the load.
Throughout the entire application process, in the event of a load short circuit fault or during maintenance due to load, the load should first be disconnected, followed by pressing the "Reset" button. Alternatively, you can also turn on the power supply again, and the working voltage will be restored to operation. Connect the load after the fault is detected.
When using a AC adjustable voltage power supply to串联 various switch mode power supplies with different rated voltages, the output current is the rated current of the path with the lowest rated current among them. 400HZ variable frequency power supply
6. Each power supply unit features a gauge indicating the output current or voltage of its respective circuit, which is typically placed in the working voltage indicator section, distinguishing between A/V conditions.
Each circuit features two output terminals, red and black, with the red terminal indicating “+” and the black terminal indicating “-”. The center of the control panel contains a black terminal marked “ground,” which indicates that this terminal connects to the housing and has no electrical connection to any output circuit, serving solely as a security line. Often, people mistakenly assume that the “ground” mark indicates a grounding device, while “+” and “-” denote the positive and negative poles of a dual-channel switch power supply output that powers a dual-power switch operational amplifier system.
8. The dual-voltage operation is not suitable for series applications. It is strictly prohibited to use it in series. Switched-mode power supplies are demand equipment, hence, it is not allowed to have a long-term short-circuit fault at the output terminal. 400HZ power supply
