NX-3500 Real Silent Power Supply 350Watt Special Edition

The Nexus NX-3500 Special Edition is the latest edition to the Nexus Real Silent power supply series. The Nexus NX-3500 Special Edition is equipped with a large 12 cm fan which provides sufficient airflow to cool the power supply at very low speed and at a very low noise level. This power supply configuration produces only 19.2 dB(A) in idle mode and will be inaudible when mounted in a computer system as the fan will be located on the inside of the computer case. The NX-3500 has longer power cables and is SATA ready!

• Real silent power supply, only 19.2 dB(A) in idle mode

• Real silent large 12 cm orange fan

• High efficiency, Excellent air flow

• Output over voltage protection

• Short circuit protection on all output

• Reset Table power shut down

• Approved by: TÜV, CSA, UL, NEMKO, FCC, C-tick, BSMI, CE

• 100% burn-in under high ambient temperature (50^oC)

• Vacuum-impregnated transformer

• MTBF: 100K hours at 25^oC

• 100% Hi-pot tested

• Line input fuse protection

• Longer power cables

• SATA ready!

• 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: 10.0mS 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.)

  • +12V : 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 : 81A(max.)

  • +5V    : 65A(max.)

  • +12V  : 30A(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.)

  • -5V       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 65% min. measured at normal AC mains voltage and frequency with maximum loads on all outputs.

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

• Temperature range:

  • operating 0^oC~50^oC

  • storage -20^oC~+65^oC

• Relative Humidity: 90%

• Safety requirements: TUV, NEMKO + CB REPORT

• 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 0.5mA

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