TNN 500AF

High-Efficienc , Fanless Power Suppl
The po er supply uses high-efficiency FET
components and Heat Source Contact (HSC)
technology, eliminating the need for a fan, and
has a 10% higher po er conversion efficiency
(80%) rating than conventional po er supplies.
Heat from the po er supply is transferred
directly to the high-capacity heatsink plates,
here it is dissipated by natural convection,
making the po er supply free of noise and
vibration.
- High-capacity active PFC inductors, separate s itching transformers for each po er rail
(+12V, +5V, +3.3V), and 2-FET for ard converter design all ork to create a superior
level of stable po er quality.
- Conventional po er supplies tend to have lo er output voltage due to line-dropping
phenomenon. The TNN Po er Supply extends the output voltage sensors up to the
motherboard connection for +3.3V, +5V, and +12V rails to prevent this, enhancing
output voltage accuracy and assuring system stability.
※
Data above ere measured according to INTEL ATX v2.03/ATX12V po er supply specs.
Measurement specifications : For each DC output, a bypass made up of one 0.1μF
ceramic capacitor and one 10μF electrolytic capacitor is connected and measured ith
an oscilloscope (input impedance 1MΩ) at a frequency band idth of 20MHz. The
aveforms may differ under different measurement conditions.

3) Electricity Conservation
Since TNN 500AF is equipped ith a high-efficiency po er supply and does not use any
fans, it utilizes 10 to 15% less po er compared to a conventional computer system under the
same configuration.
