Precision Control for Delicate Electronics
The K3010D is engineered to provide stable, low-noise power for sensitive diagnostic tasks. Unlike basic adapters, it features Dual-Mode functionality, automatically switching between Constant Voltage (CV) and Constant Current (CC). This is a critical safety feature: in CC mode, the unit will automatically lower the voltage if a circuit draws more current than your pre-set limit, preventing “fried” components and melted traces during initial power-up tests.
Key Technical Pillars & Semantic Entities:
-
High-Resolution Display: The 4-digit LED screen provides a resolution of 0.01V and 0.01A, allowing for the minute adjustments necessary when troubleshooting mobile phone logic boards or small microcontrollers.
-
Intelligent Thermal Management: An integrated 8cm smart fan only activates when internal temperatures rise, ensuring silent operation during low-load tasks while providing aggressive cooling during 10A high-load sessions.
-
Advanced Protection Suite:
-
OCP (Over-Current Protection): Limits output to protect the load.
-
OTP (Over-Temperature Protection): Safely shuts down if the unit overheats.
-
OPP (Over-Power Protection): Prevents the unit from exceeding its 300W capacity.
-
-
Fine & Coarse Adjustment: Equipped with separate potentiometers (or digital encoders) for both voltage and current, enabling the user to quickly dial in a rough value and then “zero in” on an exact target.
-
Lightweight Switching Design: At roughly 1.35kg to 2.0kg, it is significantly more portable than older linear power supplies of the same power rating, making it easy to move around a crowded workshop.
Technical Specifications:
| Parameter | Specification |
| Output Voltage | 0 – 30V (Adjustable) |
| Output Current | 0 – 10A (Adjustable) |
| Output Power | 300W Max |
| Input Voltage | AC 110V/220V $\pm$ 10% (Switchable) |
| Display Accuracy | $\pm$ 0.5% $\pm$ 1 digit |
| Ripple & Noise | $\le$ 10mVrms (Voltage) / $\le$ 20mArms (Current) |
| Protection | Short circuit, Overload, Over-temp, OVP |
Safety Reminder: Always verify the 110V/220V selector switch on the rear of the unit matches your local mains voltage before plugging it in. Running a 110V-set unit on 220V power will blow the internal fuse and likely damage the switching circuitry.
