DESCRIPTION SWITCHING MODE

AC ADAPTER

REVISED DATE:

shown below when measured under constant load range of 0.01 ~2A

with an oscilloscope with at bandwidth of 20MHz.

TABLE 2.2.5

Output # Voltage Maximum peak to peak ripple and noise

1 +12V 120 mV

NOTE: Test measurement will be made at the output connector on the power

Supply output cord. With used an aluminum Electrolytic capacitor of 10uf and

ceramic of 0.1uf parallel on output terminal can prevent unknown noise pick up.

2.3 Transient Response and Deviation

The load regulation for +12V is less than +/-10% while the measuring is down by

changing the measured output loading from +20% to +80% of rated load .

2.4 Turn on, Hold up Time

During turn on and turn off, no voltage shall exceed its nominal voltage by more

than 10% and no output will change its polarity with respect to its return line. All

outputs shall reach their steady state values within 2 seconds of turn on and the

hold up time for the output must be at least 10 mS tested at 110VAC/50HZ input

with 80% maximum load on output.

2.5 Efficiency

The efficiency (watt out/watt in) shall be a minimum of 78.6 % under line

input 115Vac/60Hz and full load.

3.0 PROTECTION

3.1 Input Current

An input fuse with a rating of 2A/250V Amps, shall be provided to protect the

power supply and the input wiring. Note: The fuse shall be an unchangeable unit.

3.2 Output Voltage (OVP)

The power supply shall shut down all outputs when any output voltage reaches to

it’s over voltage protection trigger point. ( Maximum=130% output voltage)

Note: This is not a repeatable test, when it triggers it is a perennial shut down.

3.3 Output Current (OCP)

Overload conditions shall cause both the output current and the output voltages to

decrease. Removal of an output overload conditions shall permit automatic

recovery of the output voltage. The over current protection point Maximum=300%

for all outputs . Note : The total output power should not over Rated power to

operate ,otherwise will caused the power supply to damage.

3.4 Short Circuit Protection (SCP)

The power supply shall be protected from damage of accidentally short on the

output terminal.
