PWX750ML
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 PWX750ML 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 PWX750ML 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)
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)
• The specifications of the PWX750ML apply to the rear panel output terminals.
AC input
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).
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 PWX750ML 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.
