Every serious mobile repair bench needs one tool that anchors the entire diagnostic workflow — a power supply you can trust completely. The Sunshine P-3005A fills that role. This is not a budget bench supply that guesses at output; it is a precision-engineered, programmable DC power source delivering 0–30V and 0–5A with 10mV and 1mA resolution, built by a brand that has served the global mobile repair industry since 1998.
Built for Real Workshop Conditions
When a dead phone lands on your workbench, your first move is controlled power-on. The P-3005A lets you set exactly the voltage your target device needs — 3.8V for a Samsung motherboard test, 4.2V for an iPhone boot-up check — before you connect anything. That level of control protects the logic board from voltage spikes and helps you immediately read current draw, so you know whether you are dealing with a short circuit, a software fault, or a dead IC before you even open a hot air station or pick up your soldering iron.
The 4-bit digital display reads voltage and current simultaneously with clean, high-visibility LED output. Coarse and fine adjustment controls for both voltage and current channels mean you make big jumps fast and fine-tune precisely — no fumbling, no overshooting your target.
Five-Group Memory System — Your Workflow, Your Settings
Repair shops handle dozens of device models daily, and each model demands a different power profile. The P-3005A stores five independent parameter sets in non-volatile memory. Power-off does not erase your configurations. Whether you recall your Qualcomm boot voltage, your MediaTek diagnosis setting, or your standard PCB test profile, one button press brings it up instantly. This eliminates the repeated re-adjustment that slows down high-volume workshops.
Constant Voltage / Constant Current Modes
The unit operates in CV (constant voltage) and CC (constant current) modes with automatic crossover. When a device draws more current than your set limit — like a board with a shorted IC — the supply switches to CC mode instantly, caps the current, and protects both the device and your supply. This is exactly the behavior you need when diagnosing charging issues or hunting a hardware fault on a logic board without burning components.
Thermal Protection That Thinks for Itself
Inside the P-3005A, a temperature-sensing circuit monitors internal heat continuously. When the internal temperature crosses 40°C during heavy workloads, the cooling fan activates automatically. If the connected load exceeds the machine's maximum capacity, the unit shuts output down immediately and protects itself. This is why Sunshine's design has survived more than a decade of continuous field use in workshops across 100+ countries — the protection system is real, not marketing copy.
Low Noise Output for Sensitive PCB Work
Mobile phone logic boards, especially those with RF components and power management ICs, are sensitive to ripple and electrical noise. The P-3005A delivers a clean, low-ripple DC output that will not inject noise artifacts into your measurements or destabilize sensitive circuits during diagnostics. Technicians working on network issues or display problems caused by power IC faults will immediately appreciate this cleanliness during current monitoring sessions.
Input Voltage Flexibility
The supply accepts both 110V and 220V AC input (switchable), making it fully compatible with Pakistan's standard 220V mains supply and compatible with international workshop setups. The 50/60Hz input frequency support adds further flexibility.
Where It Fits in Your Repair Workflow
The P-3005A connects directly into the heart of your diagnostics process. Use it alongside your multimeter for current leakage testing. Pair it with a PCB holder and microscope for logic board fault isolation. Reach for it before your hot air station or soldering station when a board shows charging issues or hang-on-logo symptoms. It works upstream of your test boxes and downstream of your ISP pinout tools whenever you need controlled power delivery during programming attempts on dead-phone scenarios.
If you handle hardware faults, motherboard short-circuit diagnosis, IC change work, or post-repair verification on any mobile device — Android or iPhone — this supply belongs permanently on your bench, not in a drawer.
