An SMPS converts AC mains power (like 100–240 VAC) into regulated DC output with high efficiency and compact size. The current rating (in amps) tells you how much load the supply can drive.
For example:
-
5 A output → Suitable for lighting strips, CCTV, small LED loads
-
10 A output → Larger LED systems, modules, small appliances
-
16 A/25 A outputs → Heavy loads like industrial LEDs, motors, controllers

Common Ratings & Their Uses
💡 5 A SMPS
-
Output: 12 V DC @ 5 A (≈ 60 W)
-
Best For:
• LED strip lighting (up to ~6 m of ~14.4 W/m LED)
• CCTV cameras and accessories
• Small LED modules -
Features: Compact, budget-friendly, low heat
💡 10 A SMPS
-
Output: 12 V DC @ 10 A (≈ 120 W)
-
Best For:
• Longer LED strips (up to ~12 m)
• LED signage lighting
• Camera + DVR + accessories combined loads -
Features: More headroom for stable voltage under heavier loads
💡 16 A SMPS
-
Output: 12 V DC @ 16 A (≈ 192 W)
-
Best For:
• Dense LED installations (high wattage strips)
• Industrial control circuits
• Powering multiple devices from one supply -
Features: Good for mid-range commercial installs
💡 25 A SMPS
-
Output: 12 V DC @ 25 A (≈ 300 W)
-
Best For:
• Large LED arrays
• Stage lighting controllers
• Power hub for multiple circuits -
Features: High capacity, often bulkier, may include cooling fan

🧠Why Choose SMPS?
✔ Efficient: Much lower energy loss than old transformers
✔ Lightweight & Compact
✔ Stable DC Output for electronics
✔ Protection Features (over-current/voltage)
📌 Usage Tips
🔹 Always choose an SMPS with 20–30 % higher current than your load so it runs cool and lasts longer.
Example: If your LED load is 8 A → choose a 10 A or 12 A supply.
🔹 Check output voltage (5 V, 12 V, 24 V) matches your device.
🔹 Ensure good cooling — larger units often have fans.
