Reliability
Reliability of electronic semiconductor equipment depends heavily on the
temperature of the components. The lower the temperature of the components, the
better the reliability. The Agilent E3631A incorporates circuitry to reduce the internal
power dissipation of the power supply and therefore reduce the internal heat of the
power supply. Maximum internal power dissipation occurs at maximum current. The
internal power dissipation further increases as the output voltage is lowered. A fan
internal to the Agilent E3631A is essential to keep internal temperatures low. To assist
in cooling the Agilent E3631A the sides and rear of the Agilent E3631A should be
kept clear.
