SMT-012-060VP is 12v 60w desktop type switching power adapter. It has 18 months warranty and passed CE certification.


2. INPUT REQUIREMENTS of switching power adapter:

2.1 Operating range: 90-264VAC
2.2 Rated Input Voltage :100-240VAC
2.3 Input Frequency Range: 50/60Hz +/-3Hz
2.4 Input In-rush Current: 100A max
2.5 Input Current:1.5A max
 
3.OUTPUT REQUIREMENTS of switching power adapter 12v:


3.1   Output Voltage Regulation 
   The total output voltage regulation shall be +/-5%,including the effects of line voltage variations,load current,ripple and noise,and the AC component of the load current.
 
3.2   Output Voltage Ripple
   The switching power supply shall not exceed the following limits in the indicated voltage for 60Hz or 50Hz ripple,switching frequency ripple and noise measured with 20MHz width.
   Ripple and Noise:50/60Hz Ripple + Switching Ripple and Noise
  
Ripple and Noise are measured at the end of output cables which are added a
0.1uF(104) Ceramic capacitor and a 22uF Electrolytic capacitor.
 
4. EFFICIENCY of 12v laptop adapter:

   When 120VAC line input voltage (100-240 VAC),the efficiency shall be >87% at rating load.
