The S-200-12 is an industry-standard, enclosed 200W AC-to-DC switching power supply that outputs a regulated 12V DC. It is widely used to run low-voltage hardware such as LED strip lights, CCTV security cameras, and 3D printers. 
Key Specifications
Output Voltage: 12V DC (usually adjustable via an integrated trimming potentiometer from ~10V to 14V).
Output Current: 16.5A to 16.7A maximum.
Total Power: 200 Watts.
Input Voltage: Dual-voltage compatible (110V AC or 220V AC), manually selectable via a side slide switch.
Cooling: Housed in a ventilated aluminum mesh casing for passive heat dissipation.
Protections: Built-in safety features against short circuits, overloads, and over-voltages. 
 
Product Availability & Recommendations
The "S-200-12" model nomenclature is used by several electronic component manufacturers and distributors, ranging from generic industrial brands to premium manufacturers. 
Generic S-200-12 Regulated Switching Power Supply:
Standard, cost-effective industrial unit built with an aluminum mesh box structure.
Ideal for hobbyist or budget-conscious installations where high-tier brand certification is not mandatory.
Can be purchased from general online platforms, with options listed on Dick Smith, eBay, and Amazon Australia. 
 
Terminal Wiring Layout
The unit features an open terminal block protected by a plastic flip-cover. Wiring must be completed manually using the screw terminals, typically organized as follows: 
AC Input Terminals:
L (Live/Line): Connects to the active AC wire (typically Brown or Black).
N (Neutral): Connects to the neutral AC wire (typically Blue or White).
⏚ / FG (Frame Ground): Connects to the earth safety wire (typically Green or Yellow/Green).
DC Output Terminals:
-V / COM: Negative DC output lines connecting to your LED negative terminal.
+V: Positive DC output lines connecting to your LED positive terminal. 
V+ ADJ: A small plastic dial (potentiometer) located next to the terminals used to fine-tune the 12V output voltage.
⚠️ Safety Warning: Ensure the mains power is completely disconnected before touching any terminal screws. Always double-check that the manual input voltage switch (110V vs 220V) matches your wall outlet voltage before powering the unit up to avoid immediate component damage.
