Input Current: 

1. Output Power 
Voltage (+12Vdc) Min Load ( 0A ) Max Load( 2A ) Peak Power( 3.5) Output Power( 24W)
2. Load Characteristic /Regulation rate 
Voltage (+12Vdc) Min No load(12.0V) Max No load voltage(12.4V) Line Regulation( ±3% ) Load Regulation( ±5%)
3. Ripple and Noise
Test Condition :

Voltage- Max Ripple & Max Noise :12.0Vdc 120mVp-p
4. Start Delaying Time 
When Input 115Vac and Output reach to max load,  max start time 2S
5. Rising Time 
When Input 115Vac and output reach to max load ,the max time is 40mS 
6. Keeping  time 
When input 115V and output reach to max load, min keep time 5mS。
5mS Min. At 115Vac input and output Max. Load.
7. Efficiency 
When input 100Vac and output reach to max load ,min 80%
When input 240Vac and output reach to max load , min 85% 
8.Overswing  
When power start or turn off ,max 15% 

Protection :
1.Short-Circuit and Over voltage production :
When output occurs short circuit ,the power will start protection circuit ,and will auto-recovering  when the short circuit be removed 
2. Over Current Protection 
When output current surpss rated data , the power will start protection circuit ,after solving short-circuit ,the power will recover automatically .
3. Over Voltage Protection 
When Output voltage over rated data, the power will start protection circuit  ,after ending the problem ,it will recover automatically  

Environment requirement 

1. work temperature : 0℃ - 40℃
2. Storage temperature : -20℃ - 85℃
3. Storage humidity: 5% - 90%RH
4. Insulation Withstand: AC 3000V(Min),5mA(Max)
5. Insulation Interference: DC 500V  100MΩ(Min)
