above input voltage range.
Input voltage range for PAH0S8 Series is indicated below.
Basically，ripple voltage (Vrpl) which results from rectification
When this value is exceeded, the output ripple voltage be-
Note that sudden input voltage change may cause variation
Also, input voltage waveform peak value must not exceed
Allowable input ripple voltage : 4Vp-p
Input Voltage Range : 36 - 76VDC
