Variable DC Bench Power Supply for Mobile Repairing – 15V 2A / 30V 5A Adjustable Digital Lab Power Supply in Pakistan

Overview 

A precision Variable DC Power Supply is the ultimate diagnostic station for smartphone, tablet, and laptop repair technicians. It delivers clean, regulated, and adjustable direct current (DC), allowing you to safely power up bare motherboards without needing a charged battery. By closely watching the digital LED display, a technician can pinpoint if a phone has a dead boot IC, a shorted capacitor, or a corrupted software loop simply by reading its real-time milliampere (mA) current draw.

Why Every Mobile Technician Needs This Tool 

• Battery Elimination: Safely boot up iPhones, Samsung, and other Android devices directly from the motherboard pads.

• Fault Diagnosis: Analyze precise boot currents. For example, a sudden high current draw right at power-up immediately reveals a hardware short-circuit.

• Short Circuit Invalidation: Deliver low voltage and high current directly to a shorted line to isolate heating components (often used alongside rosin atomizers or thermal cameras).

Key Features 

• Dual Digital Displays: Large, high-visibility LED readouts show output Voltage (V) and Current (A) simultaneously in real-time.

• Fine and Coarse Tuning: Equipped with dedicated knobs for both rough adjustments and ultra-fine modifications down to 0.01V.

• Automatic Short-Circuit Protection: Instant cut-off feature prevents accidental reverse-polarity or excessive current spikes from destroying sensitive mobile CPUs.

• Constant Voltage & Constant Current (CV/CC): Seamlessly switches between constant voltage mode (for general powering) and constant current mode (for battery boosting and safe troubleshooting).
