DC Power Supply Specifications
Safety considerations
The U3606B is a safety class I instrument, which means it
has a protective earth terminal. The terminal must be
connected to an earth ground through a power source with a
3- wire ground receptacle.
The DC power supply performance specifications are listed
in the following pages. Specifications are warranted in the
temperature range of 0 °C to 55 °C with a fix resistive load.
Supplemental characteristics — which are not warranted, but
are descriptions of performance — are determined either by
design or testing.
Specifications assumptions
• Specifications stated are after 60 minutes of warm- up
with no load.
• Operating temperature at 18 °C to 28 °C (64.4 °F to
82.4 °F)
• Accuracy is expressed as: ±(% of output + offset) at 23 °C
± 5 °C
• Temperature coefficient: Add [0.1 × (the specified
accuracy) / °C] for 0 °C to 18 °C and 28 °C to 55 °C
• Relative humidity (RH) up to 80% at 30 °C, proportional
to 50% for 30 °C to 55 °C
