Repair Lab Power Supplies: Types, Buying Tips & Model Comparisons
A practical, Nepal market–ready guide by GSMBAZAR for mobile & electronics repair professionals.
What a DC Power Supply Does—and Why It Matters
In board-level repair and diagnostics, a reliable DC power supply is essential. It delivers a stable, adjustable voltage and current so you can safely power devices, simulate batteries, and analyze faults without risking damage. Look for constant voltage (CV) and constant current (CC) modes, clear readouts for V/A/W, and protections like over-current and over-voltage.
- Safety & protection: OVP/OCP/OTP reduce accidental damage.
- Precision control: Fine adjustment + CV/CC let you dial in exactly what a board needs.
- Real-time monitoring: Live V/A/W readings help catch shorts, boot loops, and abnormal draw.
- Versatility: One unit can handle smartphone, tablet, small electronics, and prototyping work.
How to Choose Based on Work Type
| Task | What to prioritize |
|---|---|
| Smartphone/board diagnostics | Stable 0–30V range, 5–6A headroom, fast short-circuit response, CV/CC |
| Boot/flash testing | Clean output (low ripple), accurate current readout to observe boot sequence |
| Battery simulation/charging | Higher current (≥5A), precise current limiting, robust OCP |
| Prototyping & lab use | Fine voltage steps, memory presets, reliable cooling, clear display |
| General workshop | Rugged build, easy knobs/keys, clear screen, small footprint |
