EMI Standards :Reference EN50082-1
Safety Standards:The adapter shall be meet certified with the following safety standards ,UL61347-1,EN61347-1, GB4943-2001
DC Output Cable
Wire : (Optional) SPT-1 20AWG*2C L=1200mm Color: Black
Plug : (Optional) 5.5*2.1*10mm
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
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.
Short Circuit Protection
If short circuit occurs,all the output should be protected. After the fault, the
adapter automatically recovers.
The Output over shoot at turn-on shall not exceed 10% of normal voltage value
with or without the load connected.
The start-up time is less than 2 second.
