Here are the parameters of the MEANWELL PS-05-12 5W single - output switching power supply:
Input Parameters
Input Voltage Range: 85 - 264VAC or 120 - 370VDC.
Input Frequency: 47 - 440Hz.
Output Parameters
Output Voltage: 12VDC.
Output Current: 0.42A.
Rated Power: 5.04W.
Ripple and Noise: Typically 100mVp - p.
Output Voltage Accuracy: ±2.0%.
