protection           input over current protection
    afuse resistorin the input circuit loop, if any input over current occurs,the fuse will opened. the power supply will work after a new fuse being installed.
output over voltage protection
if any over voltage occurs, the power supply shouldclamp. the power supply will be automatically recovered after the over voltage fault being removed.
output current protection
if any over current occurs, the power supply should latch off before any output exceeds its limit below:
nominal current
over current range
0.55
0-0.6a
the power supply will be automatically recovered after the over voltage fault being removed.
output short circuit protection
short circuit occurred on +9v output should not cause any damage to the power supplybut shut down the power supply. the power supply will be automatically recovered.
over load protection
   an over protection will be effected when overloading reaches 110%-130% max. load. the power supply will be automatically recovered.
efficiency/rise temperature & noise5.1 efficiency
   the efficiency to meet energy star 2.0
5.2 rise temperature & noise
   rise temperature is less than40℃when this power supply works in 25℃ambient temperature.
safety requirement7.1 insulation withstand voltage
there shall be no abnormality when 3000vac(sensing current10ma) is impressed across ac connector and dc terminal for one minute.
7.2 insulation resistance
shall be 100mω or more, measure with 500vdc connected between input connector and dc terminal.
7.3 leakage current:≤0.25ma,100vac, full load
8.  burn-in test
100% burn-in tested at max load under 40+/-5 degree centigrade.
9. weight: this power supply is about45g
