The power supply fan speed is regulated in reference to its internal temperature
 sensor.  Our special low-friction fan turns slowly at low temperatures, reducing power
 consumption and greatly reducing fan noise. Conversely, the fan is allowed to spin
 up its speed in response to temperature increase.  The fan speed ranges roughly from 700
 RPM to a full speed of 2800 RPM.

 The AFC feature, in general, extends fan life, cuts down energy consumption, and
 reduce the chance of over-heating.   AFC is one step above the basic low friction
 "Noise Killer" fan deployment.

Noise Report

The above report is based on a HPC-300-102 operating under 24 degree C ambiant
temperature.  We tested the noise level 100cm away from the power supply, simulating
a normal usage environment.

• OVER-VOLTAGE PROTECTION
  The +5V/+12V/+3.3V DC output are protected against the over voltage condition.
  Maximum value can't be over 6.8V at 5V terminal, 15.6V at 12V and 4.5V at 3.3V.

• OVER-POWER PROTECTION
  The power supply can be used electronic circuit to limit the output current
  against exceeding 60% of surge output or protected against excessive delivery
  since short circuit of any output or over total power at nominal line.

• SHORT-CIRCUIT PROTECTION
  Short ciecuit placed on any DC output will shut down all DC outputs and latch
  Standby power will be auto recovery.

For example, all units are burned in for over 4 hours in a 45 ^oC to 50 ^oC (105 ^oF to 122 ^oF) environment and then individually tested to our specifications and all safety related standards.
