In electronic experiments, industrial testing, or DIY scenarios, DC regulated power supplies are indispensable "energy cores". However, traditional DC regulated power supplies often trap users in a "functional but not user-friendly" dilemma—poor precision with knob adjustment, easy loss of data recorded manually on paper, and single-channel output unable to meet the power supply needs of multiple devices. These pain points not only reduce work efficiency but may also affect test results due to operational errors.
As a brand focusing on DC regulated power supplies for 11 years, KUAIQU has launched a range of upgraded models based on in-depth insights into user needs, addressing traditional pain points from three dimensions: operational convenience, data management, and functional adaptability. Combined with real models and functions from the official website, this article details the "user-friendly" new experiences brought by KUAIQU's new models.
I. 3 Major Pain Points of Traditional Power Supplies: Turning "Power Supply" into a "Troublesome Task"
In laboratory or workshop scenarios, the limitations of traditional DC regulated power supplies are particularly evident, mainly focusing on three aspects: operation, data, and functions:
- Tedious Adjustment, Poor Precision: Relying on mechanical knobs to adjust voltage/current, the single fine-tuning range is large (e.g., to adjust from 12V to 12.05V, the knob needs to be twisted repeatedly). Without digital display, adjustments depend entirely on experience, leading to "a tiny error causing a huge mistake" in precision testing.
- No Data Recording, Difficult Traceability: Key data such as output voltage and current cannot be stored. Each test requires manual recording in a notebook. Subsequent report sorting is time-consuming, and data gaps may occur due to blurred handwriting or omissions.
- Single Function, Poor Adaptability: Most have single-channel output. To power multiple devices such as microcontrollers and sensors simultaneously, additional power supplies are needed, which not only occupy desktop space but also increase wiring complexity. They also lack protection functions for specific scenarios—for example, overcharging or reverse connection during battery charging may burn the device.
II. KUAIQU's New Models: 4 Upgrade Directions, Covering Full-Scenario Power Supply Needs
Targeting the pain points of traditional power supplies, KUAIQU has integrated differentiated innovative functions into 6 series of new models based on actual user operation scenarios. Below, combined with official website models and core upgrade points, we match the needs of different scenarios:
Applicable Scenarios: Electronic DIY, small-scale laboratory testing, power supply for low-power devices

Core Upgrade: Bid Farewell to Knobs, Precise and Convenient
- Encoder Adjustment: Replacing traditional four-knob resistor adjustment, it supports "coarse adjustment + fine adjustment" dual modes. Press the knob to switch digital bits and rotate to set values 0-9. The target voltage of 12V can be accurately adjusted to 12.00V with an error ≤0.01V, avoiding deviations from "adjustment by feel".
- 18W Dual Fast Charging Ports: Equipped with USB-A + Type-C ports, supporting protocols such as QC3.0/PD3.0. During testing, it can charge mobile phones and tablets simultaneously without additional power strips.
- Multiple Protection + Output Switch: Three-fold protection (OVP overvoltage, OCP overcurrent, short-circuit protection). It automatically cuts off power and sounds an alarm in case of short circuits. The independent OUTPUT switch solves the problem of "burning the load due to forgetting to turn off the output when switching parameters", eliminating the need for frequent wiring disconnection.
Scenario Test: When powering a 5V/0.5A microcontroller, traditional knobs take 1 minute of repeated adjustment. The SPS-C305S accurately sets it to 5.00V within 10 seconds via the encoder. With the USB port charging the debugging mobile phone at the same time, desktop neatness is improved by 60%.
Applicable Scenarios: Charging and maintenance of lithium batteries/lead-acid batteries/lithium iron phosphate batteries

Core Upgrade: Intelligent Charging, Safe and Non-Damaging
- Multi-Battery Type Adaptation: One-click switching between "lithium battery/lead-acid battery/lithium iron phosphate battery" modes, automatically matching the corresponding charging curve (e.g., constant current and constant voltage for lithium batteries, three-stage charging for lead-acid batteries). A 12V/12Ah lithium iron phosphate battery automatically cuts off power after being fully charged to avoid overcharging and bulging.
- Real-Time Ah Capacity Display: The 4-digit LED screen synchronously displays the charging capacity (e.g., "11.8Ah"), allowing intuitive judgment of battery charging progress without additional multimeter measurement.
- Reverse Connection Protection: When the battery positive and negative poles are reversed, the power supply has no output and triggers an alarm, avoiding the problem of burning the battery protection board due to reverse connection in traditional power supplies.
User Feedback: An electric vehicle repair shop uses the SPPS-C3010C to charge customers' batteries. Charging efficiency is increased by 30%, and there have been no battery damage disputes caused by improper charging in half a year.
Applicable Scenarios: Simultaneous power supply for multiple devices (e.g., microcontroller + sensor), DC motor drive, precision experiments

Core Upgrade: 4-in-1 Mode, 1 Device Equals 4
- Dual-Channel Independent + Series-Parallel Output: Supports three modes: "independent (2 channels of 30V/10A), series (60V/10A), parallel (30V/20A)". When powering a 12V motor + 5V sensor, the independent mode can output 12.00V/2A and 5.00V/0.3A simultaneously, eliminating the need for 2 power supplies.
- 8 Groups of Data Storage: M1-M4 keys store common parameters, such as "motor test 12V/2A" and "sensor 5V/0.5A". One-click recall is available for subsequent use, saving repeated adjustment time.
- Negative Voltage Output: Suitable for DC motor forward and reverse scenarios. The CH2 channel can be set to -12V to directly drive the motor to change direction without additional wiring to modify polarity.
Efficiency Comparison: Traditional single-channel power supplies take 30 minutes of wiring + adjustment to power 3 devices. The SPPS3010-2KD completes all settings in 10 minutes through the dual-channel independent mode, improving work efficiency by 200%.
