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 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.

Specification assumptions:

• Specifications stated are after 60-minutes of warm-up and with no load

• Operating temperature at 18 to 28 °C (64.4 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 to 18 °C and 28 to 55 °C

• Relative humidity (RH) up to 80% at 30 °C, proportional to 50% for 30 to 55 °C
