3.2 Remote On/Off Controlled mode
The PSON# signal is required to remotely turn on/off the power supply, PSON# is
an active low signal that turns on the output power rails. When this is not pulled low
by the system, or left open, the outputs (except the +5VSB) turn off. This signal is
pulled to a standby voltage by a pull-up resistor internal to the power supply.

3.4 Rise Time
DC output rise time is less than 20 mS at nominal line and full load.
3.7 PG-OK
PG-OK is a power good signal and should be asserted high by power supply to indicate
that the +5 VDC and +3.3 VDC outputs are above the under-voltage thresholds of the
power supply. When this signal is asserted high, there should be sufficient mains energy
stored by the converter to guarantee continuous power operation within specification.
Conversely, when either the +5VDC or the +3.3VDC output voltage falls below the under
-voltage threshold, or when mains power has been removed for a time sufficiently long
so that power supply operation is no longer guaranteed, PG-OK should be deasserted to
a low state. See Figure 1 for a representation of the timing characteristics of the PG-OK,
PS-ON, and germane power rail signals.
3.8 3.3V Sense
A default 3.3V sense line should be implemented pin 13 of the connector.
3.9 Capacitive Load
The power supply should be able to power up and operate normally with the following
capacitances simultaneously present on the DC outputs.

4. PROTECTION
3.5 Hold-up Time
DC +5V output maintains at least 8mS after power off which hold within para
3.1 under 230V/50Hz condition.
3.6 5VSB
5VSB is requierd for the implementation of PS-ON described above. 5VSB is
a standby voltage that may be used to power circuits that require power input
during the powered-down state of all power rails. The 5 VSB pin should deliver
5V ± 5% at a minimum of 2.5 A for PC board circuits to operate. Conversely,
PC board should draw no more than 2.5A maximum form this pin. This power
may be used to operate circuits such as soft power control.
05
4.1 Input Protection
In primary circuit of the power supply , a protected fuse is inserted.
Only internal fault of the power supply will cause the fuse blown.
Any overload or short circuit at DC output will keep from fuse brown or fire hazard.
4.2 Output Protection
4.2.1 Under voltage protection
The +5V/+3.3V DC output are protected against the under voltage condition.
Range value can't be exceed 3.3~3.7V at 5V terminal and 2.0~2.4V at 3.3V.
4.2.2 Over Voltage Protection
The +5V/+12V/+3.3V DC output are protected against the over voltage condition.
Maximum value can't be over 6.5V at 5V terminal and 15.5V at 12V, 4.3V at 3.3V.
06
4.2.3 Over Power Protection
The power supply can be used electronic circuit to limit the output current against
exceeding 60% of surge output power or protected against excessive power delivery
since short circuit of any output or over total power at high line.
4.2.4 Short Circuit Protection
Short circuit placed on +5V,+12V,+3.3V,-12V will latch off. +5VSB will auto-recovery.
5. START STABILITY
5.1 No Load Start
When power is applied to ST50F-ES & ST40F-ES with no load connected or
under minimum load connected, neither damage to power supply nor hazards
to users will occur.
5.2 Cold Start
The power supply shall operate properly when first applied at normal input voltage
and or so maximum load after 4 hours storage in 0 C environment.

9. POWER GOOD SIGNAL
A TTL compatible signal for the purpose of initiating an orderly start-up procedure
under normal input operating conditions. During power up, this signal is asserted
( low ) until +5V is under regulation and AC reaches min. line specification range.
After all voltage are going appropriate level, the system may have a turn on delay
of 100mS, but no greater than 500mS. During power off the signal should go to low
level before +5V is out of regulation. The low level is 0 to 0.8V and high level is 4.75
to 5.25V. The " Power Good "signal can drive up to 6 standard TTL loads.
