Especificaciones:

  • Remote ON/OFF Control : The power supply shall accept a logic open collector level which will disable/enable all out put voltage (excluding +5V standby)

  • Output voltage hold-up time :

    • 15.0mS minimum: at 115V / 50 Hz

    • 12.0mS minimum: at 230V / 50 Hz.

  • Operation at no load : The power supply will be capable of being operated with no load on any or all outputs without damage.

  • Over voltage protection :

    • +5V : 6.5V(max.)

    • +3.3V : 4.6V(max.)

    • +12V1 : 15.5V(max.)

    • +12V2 : 15.5V(max.)

  • Over current protection : There shall be protection from an output over-current event. The power supply may shutdown from such an event and require power-on restart. Testing consists of application of the listed over-current value with maximum load on all other outputs. Over-current test values: (maximum load)

    • +3.3V : 80A(max.)

    • +5V  : 68A(max.)

    • +12V1 : 45A(max.)

    • +12V2 : 45A(max.) 

  • Short current protection : A short circuit at any output shall cause no damage to the power supply nor blow the primary fuse. The power supply may shut down in the event of a short circuit and require power-on restart. A short circuit consists of application of a test resistance of less then 0.05 ohms at each output with maximum load on all outputs.

  • Output risetime : The cold-start enable output voltage risetime of all outputs shall be measured with maximum load on all outputs. Riseti me (10-90%):

    • +3.3V   20mS (max.)

    • +5V     20mS (max.)

    • +12V    20mS (max.)

    • +12V   20mS (max.)

    • +5Vsv  20mS (max.)

  • Output overshoot : No output voltage shall overshoot or generate spikes at turn-on or turn-off, during momentary power loss, output short, or realistic input voltage or output load changes. Overshoot is defined as any output that exceeds the voltage tolerance plus or minus an additional 5%.

  • Efficiency : Overall efficiency must be 70% min. measured at normal AC mains voltage and frequency with maximum loads on all outputs.

  • Power good signal : 115/230V (full load): 100-500mS

  • Temperature range :

    • operating 0 o C~50 o C

    • storage -20 o C~+65 o C

  • Relative Humidity : 90%

  • Safety requirements : TUV EN60950, NEMKO + CB REPORT, IEC 60950, UL 60950

  • Dielectric strenght : Primary to frame ground: 1800 Vac for 1 sec. Primary to secondary: 1800 Vac for 1 sec.

  • Insulation resistance : Primary to secondary: 20 Meg. ohms min. Primary to frame ground: 20 Meg. ohms min.

  • Ground leakage current : The power supply ground leakage current shall be less than 3.5mA

3.3V & +5V total output not exceed 200Watt
