Considerations
The following situations should be taken into consideration when
using the power supply.
Inrush current
When the power supply switch is first turned
on, an inrush current is generated. Ensure there
is enough power available for the power
supply when first turned on, especially if a
number of units are turned on at the same
time.
Caution
Allow at least 15 seconds between cycling the
power. Cycling the power on and off quickly can
cause the inrush current limiting circuit to fail as
well as reduce the working life of the input fuse
and power switch.
Pulsed or Peaked
loads
When the load has current peaks or is pulsed, it
is possible for the maximum current to exceed
the mean current value. The 2260B power
supply ammeter only indicates mean current
values, which means for pulsed current loads,
the actual current can exceed the indicated
value. For pulsed loads, the current limit must
be increased, or a power supply with a greater
capacity must be chosen. As shown below, a
pulsed load may exceed the current limit and
the indicated current on the power supply
ammeter.
