In electronic experiments, equipment debugging, and industrial production, the storage function of a DC stabilized power supply is not just for "saving parameters"—it is a key design that optimizes traditional operations in three core aspects: efficiency, precision, and safety. Compared with the old mode of "re-adjusting parameters every time you use it," it solves many pain points through "one-time setting, repeated use," significantly improving work quality and efficiency. The following will break down its core advantages and explain their value with scenarios.

1. Efficiency Advantage: Save Time and Reduce Repetition

Traditional power supplies require manual adjustment of voltage and current every time they are used, with repeated verification—a tedious process. The storage function leverages parameter reuse, showing obvious advantages in multi-scenario switching and mass production.

(1) Experimental Scenarios: Quick Parameter Switching

When debugging different devices (e.g., 5V, 12V, 24V sensors), traditional operations take 3-5 minutes each time (adjust voltage → adjust current → set protection → verify). With the storage function, 3 groups of parameters are saved in advance, and each subsequent call takes less than 20 seconds. Calculated by switching parameters 10 times a day, traditional methods take 30-50 minutes, while the storage function only takes 3.3 minutes—improving efficiency by over 80% and allowing operators to focus on the experiment itself.

(2) Industrial Scenarios: More Efficient Mass Production

During batch testing of the same product (e.g., chargers), in the traditional process, 10 workstations testing 100 products each day spend a lot of time just adjusting parameters, which easily disrupts the production rhythm. With the storage function, standard parameters (e.g., 19V/2A) are saved, and each test at each workstation saves 2 minutes. 10 workstations save 33.3 hours a day. High-end power supplies can also connect to computers/PLCs for parameter synchronization; when switching production lines, parameter updates for all devices are completed in 5 minutes, avoiding errors and time waste from manual adjustment one by one.

2. Precision Advantage: Prevent Errors and Ensure Consistency

Traditional manual parameter adjustment is prone to human influence, leading to deviations. The storage function uses digital storage and recall to control precision within the minimum resolution of the device, ensuring consistency in each operation.

(1) Reduce Human Errors

During manual adjustment, visual errors (e.g., mistakenly adjusting 12.0V to 12.1V) and "over-adjustment" or loose drift caused by mechanical gaps in knobs can lead to errors of 1%-5%. The deviation between the parameters recalled by the storage function and the initial setting is less than 0.1% (e.g., voltage precision 0.01V, current 0.001A), meeting the needs of high-precision experiments (e.g., sensor signal collection).

(2) Ensure Long-Term Consistency

• Experimental Scenarios: Capacitor life testing requires stable 15V/3A for 30 days. Traditional parameter adjustment after daily restart may have a deviation of 0.2-0.3V; the storage function ensures voltage fluctuation is less than 0.01V in 30 days, making experimental data comparable.

• Production Scenarios: Mobile phone charger testing requires 5V±0.05V and 2A±0.02A. The precision compliance rate of traditional operations is 95%; the storage function saves and locks standard parameters, increasing the compliance rate to 99.9% and reducing rework costs.

3. Safety Advantage: Reduce Risks and Protect Equipment

Traditional manual parameter adjustment is prone to equipment damage due to misoperations (e.g., parameter over-limit, missing protection settings). The storage function reduces risks from the source by presetting safe parameters and binding protection thresholds.

(1) Avoid Damage from Parameter Over-Limits

A 5V sensor will be burned instantly if mistakenly adjusted to 24V power supply. The storage function only recalls verified safe parameters (e.g., 5V/0.5A), fundamentally eliminating such misoperations. After using the storage function, a laboratory reduced the load damage rate from 3-5 times a month to zero.

(2) Quickly Restore Protection Parameters

After a load short circuit triggers over-current protection (OCP), traditional handling takes 5-8 minutes (troubleshoot → reset OCP/OVP); the storage function restores protection thresholds (e.g., OCP 2.2A, OVP 5.5V) within 1 minute, reducing production downtime. Some high-end power supplies can also "memorize fault parameters," helping operators quickly analyze the cause of faults (e.g., load overload, poor line contact).

4. Summary

The storage function of DC stabilized power supplies achieves triple improvements in efficiency, precision, and safety through "parameter reuse": it saves operation time, prevents human errors, and reduces damage risks—turning the power supply from a "passive power device" into an "assistant for improving work quality." It is an indispensable core function in multi-scenario reuse, mass production, and high-precision experiments.
