In order to further improve the user's operation experience of APM Power Supply, the following summary shares some user-friendly menu instructions, solves your daily questions, and makes your operation easier.
1. Function of limit setting
After setting the maximum and minimum limits of voltage or current, you can safely turn the knob to adjust the voltage or current on our AC Power Supply or DC Power Supply, without worrying about unexpected operation leading to over or below the required parameter output, Nice!
2. Function of quick recall function
Common voltage of daily test or debugging circuit, user stores the frequently used data 3.3V, 5V, 12V, 24V, 48V, etc. in the power supply's memory. When switching the test voltage, user can press the numeric key directly after entering the quick recall mode, can quick recall the data which are stored in [1]~[9], Nice!
3. Custom power on settings
The user can define the power setting parameter value (voltage & current), working mode (external control or panel operation) and even power output state (on or off) at the next power on, which saves the complicated configuration or setting process after each power on and is Nice!
4. Output Foldback protection function
Generally speaking, DC power supply has two output modes: constant voltage (CV) and constant current (CC). Under certain voltage and current conditions, according to the load conditions, the power supply can work in these two modes, and realize automatic switching. In practical application, if the load has strict requirements on the working mode of the power supply, it must work in a certain mode, and this automatic switching has its limitations. For example, for LED type load test, it is necessary to ensure that the power supply works in constant current (CC) mode; otherwise the object to be tested will be damaged. After adding this part of protection function, when the power output mode is converted, the power output can be turned off immediately or after a certain delay according to the parameters set by the Foldback function.
5. Measure Average Function on time setting
In the actual test process, if the DUT has a sharp change in voltage and current,, the averaging times can be adjusted to be FAST, MEDIUM or SLOW to make the displayed value more stable.
This setting does not affect the setting of the power supply and the response speed.
6. Timer Control function
This function is applicable to unattended occasions, activate the timer and the output, the screen will show the countdown of the timer. Once it reaches down to zero, the supply will turn off the output automatically. And the full protection of the power supply will make sure the safe usage of this function.
7. Key lock function
The current series of Ac Dc Power Source supports buttons, knobs, touch screens and other operating media for users to set parameters intuitively and quickly. In order to avoid the danger of disoperation or touch in the output process, the user can press lock to lock the above operation medium after setting parameters. Press the unlocking key when the parameter setting needs to be modified.
