Used ICs: IC101: L6599AD; IC202: AZ431LANTR-E1; IC251: AS431AN; IC601: SCY99102BDR2G
AC
100V to AC 240V
Inrush
Current: 80A zero-peak max at cold start and any specified line, load,
temperature conditions.
Power
Output Characteristics
On Condition:
In a moment of Power-ON Signal activated, the current of 3.5V output should be
limited within 40mA(Max) at LCD TV condition for stability. [Do not turn
“Power-ON” Signal on at the load condition of 3.5V output, more than 40mA.]
Total
regulation for each output circuit includes the results of input voltage
variation, load variation, warm-up drift and temperature change.
The
following instruments shall be used for measuring ripple noise.
1.
Probe having impedance ratio of 1:1.
2.
Oscilloscope having frequency characteristic of 100MHz or more.
Ripple
and noise are measured at the end of output cable which are added a 0.1uF
ceramic capacitor and 47uF electrolytic capacitor. (Connected parallel)
Burn-in
More
than 2 hours at 45℃(±5℃), Normal input voltage.
AC
on/off must be test 1 time after burn-in.
80%
Load of specification.
This
Power Supply has protections.
*
Short circuit protection between different output terminals is not considered.
*
Trip point for over voltage indicates the operating point when the output
voltage slowly increases.
*
The conditions of Over Current measurement Multi output(3.5V,12V,24V) is
nominal load state except an over current measurement.
