Ext. Control: AI Interface (Option)
Example:
EPS/MP 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 voltage of the unit.
Example:
EPS/MP 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 (U
OVP
)
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 rest this error, standby mode must be activated. Adjustment range is 0 V up to the
maximum rated voltage of the device + 20%.
Example:
EPS/MP 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

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
)
Present set point of the output voltage. Measurement value refers to the rated voltage of the device.
Example:
EPS/MP 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
)
Present set point of the output current. Measurement value refers to the rated current of the device.
Example:
EPS/MP 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
Monitor Actual Value P (P
mon
)
Present set point for output power. It is calculated by the controller from measurement values of output voltage and
output current. Measure value refers to the rated power of the device.
Example:
EPS/MP at 15 kW rated power, AI adjusted to 10 V, voltage at output P
mon
= 5 V.
Present output power P
out
= 5 V
*
15 kW ÷ 10 V = 7.5 kW
