PSI 9000 15U/24U Series
After setting it up, the function can be loaded.
► How to load a function
1.
After setting the values for the required signal generation, tap on the
touch area .
The device will then load the data into the internal controller and changes the
display. Shortly afterwards the static values are set (power and voltage or cur -
rent), the DC output is switched on and the touch area enabled.
Only then can the function be started.
The static values are applied to the DC output immediately after loading the function, because
it switches the DC output on automatically in order to set the start situation. They represent
start and end values for the progress of the function, so that tit doesn’t need to start from 0.
Only exception: when applying a function to the current (I), there is no adjustable static current
value, so the function would always start from 0 A.
► How to start and stop a function
1.
The function can be started either by tapping or pushing the “On/Off” button, if the DC output is
currently switched off. The function then starts immediately. In case START is used while the DC output is
still switched off, it will be switched on automatically.
2.
The function can be
stop
ped either by tapping or operating the “On/Off” button. However, there
is a difference:
a) The
button stops only the function, the DC output remains ON with the static values.
b) The “On/Off“ button stops the function and switches off the DC output.
A device alarm such as overvoltage, overheating or power failure stops the function progress
automatically and the DC output is switched off.
3.10.5 Sine wave function
The following parameters can be configured for a sine wave function:
Value Range Description
I(A), U(A) 0...(Nominal value - (Off)) of U, I A = Amplitude of the signal to be generated
I(Off), U(Off) (A)...(Nominal value - (A)) of U, I Off = Offset, based on the zero point of the mathematic sine
curve, may not be smaller than the amplitude.
f (1/t) 1...1000 Hz Static frequency of the signal to be generated

A normal sine wave signal is generated and applied to
the selected set value, e.g. voltage (U). At a constant
load resistance, the output voltage and thus also the
output current will follow a sine wave.
For calculating the maximum power output the amplitude
and offset values for the current have to be added.
Example: an output voltage of 100 V is set together with
sin(I) with an amplitude of 30 A and an offset of 50 A.
The resulting maximum power output is then achieved
at the highest point of the sine wave and is (30 A + 50
A) * 100 V = 8000 W.
