SPECIFICATION SFX-L Form Factor SST-SX500-LG 500W Switching Power Supply With Active PFC 80 Plus Gold 1. General 1.1 Scope This specification defines the performance characteristics of a single phase 500 watts, 5output 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 7.0A 90 - 264Vrms 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.
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. TTL level "H" 2.0 V - 5.25 V "L" 0.0 V – 1.0 V 3.
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.
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 16.0V at 12V, 4.5V at 3.3V. 4.2.3 Over Power Protection The power supply can be used electronic circuit to limit the output current against exceeding 50% 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.
6.1.2 Storage o Temperature -40 to 70 C Relative Humidity 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. Product Safety 7.1 Safety Requirement CE 7.2 Leakage Current The AC leakage current is less than 3.5mA when the power supply connect to 253Vac/50Hz .
8. 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.
9. MTBF The MTBF of the power should be 100,000 hours min. 10. Harmonics The product shall meet requirement for EN61000-3-2 & EN61000-3-3 :2003 standard of class D, test at 230Vac 50Hz. 11. Power Factor The power supply with active power factor correction, and meet the EN61000-3-2 standards, The power factor is greater than 0.95 at 230V/50Hz, Max. load. 12. Mechanical Specification 125 mm (W) × 63.
