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

load current.

 

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
