ANALOG INPUT
Set points are adjusted as dc voltage (0-5 V or 0-10 V) on the analog inputs. The voltage range can be chosen in the
configuration menu. To save all changes after changing the voltage range, the unit must be restarted.
Set Point U (U
Set
)
Set point output voltage. The set point refers to the rated voltage of the unit.
Example:
LAB/HP/E at 600 V output voltage, AI is adjusted to 10 V, desired output voltage = 100 V.
U
set
= 10 V
*
100 V ÷ 600 V = 1,667 V
Set Point I (I
Set
)
Set point output current. The set point refers to the rated current of the unit.
Example:
LAB/HP/E at 100 A output voltage, AI is adjusted to 10 V, desired output current = 2 A.
I
set
= 10 V
*
2 A ÷ 100 A = 0.200 V
Set Point OVP (OVP
set
)
The output is deactivated immediately if the output voltage exceeds the adjusted value. This error is indicated on the
display with the word „Error“. To reset this error, standby mode must be activated. Adjustment range is 0 V up to the
maximum rated voltage of the device + 20%.
Example:
LAB/HP/E with 600 V output voltage, AI is adjusted to 10 V, desired OVP voltage = 650 V.
Adjustment range: 600 V + 20% = 720 V
U
set
= 10 V
*
650 V ÷ 720 V = 9.028 V
ANALOG OUTPUT
On the analog outputs, present measurement values are displayed as dc voltage values (regardless of the actual
operation mode). Therefore, the AI interface can be used for monitor purposes. Maximum voltage is 5 V / 10 V.
Monitor Set Point U (U
mon
PRESET)
Present set point of the preset output voltage. Measurement value refers to the rated voltage of the device.
Example:
LAB/HP/E at 600 V output voltage, AI is adjusted to 10 V, voltage at output U
mon
= 2 V.
Present set point: U
set
= 2 V
*
600 V ÷ 10 V = 120 V
Monitor Set Point I (I
mon
PRESET)
Present set point of the preset output current. Measurement value refers to the rated current of the device.
Example:
LAB/HP/E at 100 A output current, AI adjusted to 10 V, voltage at output I
mon
= 2 V.
Present set point: I
set
= 2 V
*
100 V ÷ 10 V = 20 A
