SPECIFICATION SilverStone Strider Essential ST50F-ESB ST40F-ESB ATX12V 2.3 Switching Power Supply With Active PFC 80 Plus Bronze PS/2 1. General 1.1 Scope This specification defines the performance characteristics of a single phase 500/400 watts, 5 output power supply. This specification also defines worldwide safety and electromagnetic compatibility requirements for the power supply which is intended for use in computer products. 2. Input Characteristics 2.
2.3 Max. Input AC Current Max. Input Current Measuring Range 8A 103.5 - 253 Vrms 2.4 Inrush Current The power supply must meet inrush requirements for any rated AC voltage, during turn on at any phase of AC voltage, during a single cycle AC dropout condition, during repetitive ON/OFF cycling of AC, and over the specified temperature range. The peak inrush current shall be less than the ratings of its critical components (including input fuse, bulk rectifiers, and surge limiting device). 2.
SST-ST40F-ESB Output Load Range Peak Regulation Ripple & Noise Voltage MIN MAX +5V 0.2A 20.0A - ±5% 50mV +3.3V 0.1A 20.0A - ±5% 50mV +12V 0.6A 30.0A - ±5% 120mV -12V 0.0A 0.3A - ±10% 120mV +5Vsb 0.0A 2.5A 3.5A ±5% 50mV P-P Max. Maximum continuous total DC output power should not exceed 400W. Maximum continuous combined load on +3.3VDC and +5VDC outputs shall not exceed 103W. Maximum combined load on 12V outputs shall not exceed 360W.
3.5 Hold-up Time DC +5V output maintains at least 16mS ,after power off , under 230V/50Hz 75%Load 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.
4. Protection 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.
6. Environments 6.1 Temperature and Humidity 6.1.1 Operating Temperature Relative Humidity o 0 to 40 C 20 to 90 % 6.1.2 Storage Temperature Relative Humidity o -40 to 70 C 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 0.35 mm 7. Conducted EMI CE , FCC 8.
8.4 Dielectric Voltage Withstand The power supply shall withstand for 1 minute without breakdown the application of a 60Hz 1500V AC voltage applied between both input line and chassis (20mA DC cut-off current). Main transformer shall similarly withstand 3000Vac applied between both primary and secondary windings for a minimum of one minute. 9. Power Good Signal A TTL compatible signal for the purpose of initiating an orderly start-up procedure under normal input operating conditions.
10. MTBF The MTBF of the power should be 50,000 hours min. 11. Burn-In 11.1 Input Voltage Applying 220Vac for230Vac model. 11.2 Test Condition Applying 75% loads for the power supply in 40 (+/-5) oC chamber for 4 hours. 12. Harmonics The product shall meet requirement for EN61000-3-2 & EN61000-3-3 :2003 standard of class D, test at 230Vac 50Hz. 13. Power Factor The power supply with active power factor correction, and meet the EN61000-3-2 standards, The power factor is greater than 0.
