This power supply is a professional-grade tool designed for electronic engineers, lab personnel, and repair professionals. Its core selling points are "high precision, intelligence, and multi-scenario adaptability." The product details page will present its full value from the following dimensions:

I. Main Visual and Product Positioning

1. Core Positioning

The title directly states "Programmable Intelligent DC Regulated Power Supply," highlighting its core features: 2.8-inch touchscreen | APP control | multi-functional programmable, while emphasizing its professional attributes of "high stability, high precision, safety, durability, and programmable numerical control."

2. Model

MP305B (Rechargeable): Built-in high-capacity battery supports mobile use without mains power, suitable for outdoor debugging, portable repair, and other scenarios.

II. Core Functions and User Experience Details

1. 2.8-inch Capacitive Color Touchscreen

High-definition display: Real-time display of output voltage (green), current (yellow), power, as well as parameters such as operating time, accumulated energy, and protection status, providing clear and intuitive data.

Touch Operation: Supports click and swipe switching functions, combined with a physical knob for auxiliary adjustment, providing smooth and precise operation and avoiding the lag of traditional buttons.

Interaction Logic: The interface is clearly divided, including shortcut buttons for "Save/Load Presets," "Mode Switching," and "Protection Settings," allowing professional users to quickly get started.

2. Four Working Modes, Multi-Functional Use

The details page will highlight the practicality of mode switching:

Linear Regulated DC Power Supply Mode: Provides continuously adjustable output from 0~30V/0~5A, with low output ripple and low noise, meeting the needs of precision circuit testing.

Programmable DC Power Supply Mode: Supports custom voltage/current change curves (such as stepped or ramped output), and allows setting parameters such as delay and cycling, suitable for aging tests and dynamic characteristic verification.

USB-C PD Power Mode: Integrates PD fast charging output, capable of powering mobile phones, laptops, and other devices, balancing utility and versatility.

Universal Charger Mode: Supports constant current and constant voltage charging for various battery types (such as lithium batteries and lead-acid batteries), suitable for battery activation after electronic device repair.

3. Intelligent Interconnection and Programmable Control

APP Host Computer Control: Connects to a mobile phone/computer APP via Bluetooth, allowing remote parameter adjustment, output status monitoring, and work log export, suitable for batch testing or unattended operation scenarios.

Preset Storage Function: Supports saving multiple sets of voltage/current parameters, which can be loaded with one click when recalled, reducing efficiency loss from repeated adjustments.

Safety Protection Mechanism: Built-in OCP (overcurrent protection), OVP (overvoltage protection), and OTP (overheat protection) functions, with real-time screen alarms when protection is triggered to prevent equipment damage.

4. Efficient Heat Dissipation and Stable Output

Heat Dissipation System: Adopts a combination of aluminum alloy heat sink body and silent high-speed fan, quickly conducting and dissipating heat, maintaining stable temperature even during long-term high-load operation, and avoiding output drift caused by overheating.

Linear Output Characteristics: Emphasizing "low ripple and low noise" linear voltage regulation technology, the output voltage accuracy reaches ±0.01V, and the current accuracy reaches ±0.001A, meeting laboratory-level testing requirements.
