PWX
Unless specified otherwise, the specifications are for the following settings and conditions.
• Loads are pure resistive loads.
• The warm-up time is 30 minutes (with current flowing).
• After the PWX has been warmed up, it must be calibrated correctly in a
23 °C ± 5 °C environment according to the procedures given in the operation manual.
• Values indicated by “TYP” are typical values. They are not guaranteed performance values.
• Values indicated by “rtg” are rated values.
• Values indicated by “rdng” are readout values.
• The PWX operates over a wide range of output voltage and output current within rated output power.
However, the current that can be output with rated output voltage and the voltage that can be output with
rated output current are limited by the rated output power.
• The current that can be output with rated output voltage and the voltage that can be output with rated
output current are as follows.
Maximum output current with rated output voltage = Rated output power/rated output voltage.
Maximum output voltage with rated output current = Rated output power/rated output current.
• Rated load and no load are defined as follows:
In constant-voltage mode (when the output current is set to a value greater than or equal to the max-
imum output current with rated output voltage)
Rated load: Refers to a resistive load that, when the rated output voltage is applied, makes the
flowing current 95 % to 100 % of the maximum output current with rated output
voltage.
No load: Refers to a load through which no output current flows. In other words, refers to an
open load (no load being connected).
In constant-current mode (when the output voltage is set to a value greater than or equal to the max-
imum output voltage with rated output current).
Rated load: Refers to a resistive load that, when the rated output current flows, makes the voltage
drop to 95 % to 100 % of the maximum output voltage with rated output current.
Including the voltage drop in the load cables, the PWX output voltage must not exceed
the maximum output voltage with rated output current.
No load: Refers to a resistive load that, when the rated output current flows, makes the voltage
drop to 10 % of the maximum output voltage with rated output current or 1 V
whichever is higher.
• The specifications of the PWX apply to the rear panel output terminals.
