Features: This listing is for one Sub-Mini Switching Power Supply Transformer Regulated LED Lighting 180-220V for CCTV Security Camera, LED.
Specification: Condition: New Power: 12V 5A /8.3A/10A/12.5A/16.5A/20A/30A Output Voltage: 12V Efficiency: 80% Output Ripple Noise: 100mV Output Voltage Accuracy: 10% Load Regulation Rate: 5% High quality and high performance. Protections: overload/over voltage/short circuit.
About Calculate Method: If Your LED Strip 60LEDs/m, and each LED 0.2W, then calculate max LED Strip Length: 0.2W/LED × 60LEDs/m=12W/m, for example,24W÷12W/m=2m, so, support the LED Strip(60LEDs/m, 0.2W/LED) Length (Max)=2m. AC: Alternating Current DC: Direct Current L/N: Connect Alternating Current -V (COM): Output Negative + V: Output Positive (The output polarity cann't be reversed.) FG: Connect Ground Wire ADJ: Output Voltage Trimmer
