Power Supply Specification
Power supply constitutes an essential part of the panel PCs, so we make this
section to let you know more about the power supply used in them. It is a
universal 250W AC switching power supply (default).
Industrial Features:

℃
operating temperature
l
High reliability “Ball Bearing” cooling fan
l
High precision and stable DC outputs for long term operation
General Specifications:
Ripple and Noise:
The peak-to-peak ripple and noise for +12V is less than
140mV. The other outputs are less than 1% of each output voltage at rated load.
Measurement is done by 15MHz-band width limited oscilloscope and terminated
at each output with a 47 uF capacitor.
Line Regulation:
The output line regulation for +12V is less than +/-2%, for
other outputs are less than +/-1% while measuring at rated load and +/-10% of
input voltage changing.
Load regulation:
The output voltage load regulation is less than the values in the
following table by changing each output load +/-40% from 60% rated load, and
keep all other outputs at 60% rated load.
