The return values in the variables
CurrentSet
and
CurrentLimit
are currents in A. The latter is the limit of the output current, the value
CurrentSet
is the current that was previously set by the function
COM_HVPSU2D_SetPSUOutputCurrent
. However, it is adjusted to
be lower than or equal to the current limit
CurrentLimit
.
The direct command (

) contains one decimal character (
n
) for
the variable
PSU
. The response (

) contains the
decimal character (

PSU
followed by 2 x 6
hexadecimal digits for the variables
CurrentSet
(
SSSSSS
) and
CurrentLimit
(
LLLLLL
). The current values are in µA,
for the parameter unit conversion, see function
COM_HVPSU2D_GetPSUOutputCurrent

Saves the measured values of the PSU module with the number
PSU
in the variables
Voltage
,
Current
, and
VoltDropout
, and returns
an error code according to Tab. 10.
The variable
PSU
is the number of the PSU module, for more details,
see function
COM_HVPSU2D_GetPSUOutputVoltage
.
The return value in the variable
Voltage
is the measured value of the
output voltage in V, the value in the variable
Current
is the meas-
ured value of the output current in A. The value in the variable
Volt-
Dropout
is the measured value of the voltage dropout on the output
voltage regulator, The voltage dropout and the output current deter-
mine the power dissipation of the PSU module. For the device to func-
tion properly, the voltage dropout should not be lower than 5-10 V.
