Switching Power Supply Specifications 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 powereddown state of all power rails. The 5 VSB pin should deliver 5V ± 5% at a minimum of 3.0 A for PC board circuits to operate. Conversely, PC board should draw no more than 3.0A maximum form this pin. This power may be used to operate circuits such as soft power control. 3.
Switching Power Supply Specifications 4.2 Output Protection 4.2.1 Under voltage protection The +5V/+12V/+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 8.5~9.5V at 12V, 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. 4.2.
Switching Power Supply Specifications 6. Environments 6.1 Temperature and Humidity 6.1.1 6.1.2 Operating Temperature Relative Humidity Storage Temperature Relative Humidity 0 to 45 oC (See Figure 2) 20 to 90 % -40 to 70 oC 20 to 95 % noncondensing 6.2 Altitude The power supply can operate normally at any altitude between 0 to 10000 feet. 6.3 Vibration and Shock Sweep and resonance search for each of X,Y,Z, axis at the sweep. RATE of 1/OCTAVE/Min. Frequency Duration Amplitude 5-55-10 Hz 30 minutes 0.
Switching Power Supply Specifications 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.
Switching Power Supply Specifications 10. MTBF The MTBF of the power should be 100,000 hours min. 11. Burn-In 11.1 Input Voltage Applying 220Vac for 230V model. 11.2Test Condition Applying 75% loads for the power supply in 45 (+/-5) oC chamber for 4 hours. 12.Harmonics The product shall meet requirement for EN61000-3-2 & EN61000-3-3 :1995 standard of class D, test at 230Vac 50Hz. 13.
