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 E3633A and Agilent E3634A power supplies
incorporate 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 power supply is
essential to keep internal temperatures low. To assist in cooling the power supply, the
sides and rear of the power supply should be kept clear.
