Introductions
The DP-660 is a dual output, DIN-Rail mounted, 65 watts switching power supply.
It has over voltage protection in main output and over load latch off mode
protection on all output.

At Factory, all outputs in 60% rated load conditions, the +24V output is set
to between 23.76V and 24.24V and 5V is checked to be within the specified
voltage accuracy range.
Peak load can test for 10 sec. Typical when other output at rated load, AC
input at 115VAC.
2.2
Ripple and noise
the peak-to-peak ripple and noise for each output is less then 1% of output
voltage at rated load. Measuring is done by 15MHz bandwidth limited
oscilloscope and terminated each output with a 0.47uF capacitor.
2.3
Line regulation
the line regulation for each output is less then +/- 1% while measuring at
