The analog interface (15-pole D-sub socket on the rear panel) is used to control the functions voltage setting, current setting as well as OUTPUT ON/OFF and, depending on the unit type, special functions. The current actual values are provided as analog voltages and the latest control modes as digital signals.
For most models, the analog programming can be installed later at our site.
Analog programming
| Description | Control output variants | |
| Non-isolated | Due to the direct coupling of the analog signals, the device characteristics like accuracy, linearity, stability, and temperature coefficient remain unchanged.
Please note that the power supply units which are equipped with the non- isolated analog programming option CANNOT be operated potential-free! |
0 – 10V (Standard) 0 – 10V (for PLC) 0 – 5V 4 – 20mA |
| Isolated | All signals are 2kV isolated from the output potential via fiber optic.
With isolated analog programming there is no galvanic connection between the pins of the programming interface and the output sockets. On request, we can also supply a fiber optic option with isolation capabilities up to 200kV and more. |
0 – 10V (Standard) |
| Floating (max 600V) | The analog signals for voltage and current setpoint as well as voltage and current monitors are isolated from the output potential via isolation amplifiers.
Digital signals are isolated via optocouplers. Floating analog programming has the advantage of faster data transmission compared to isolated analog programming. |
0 – 10V (Standard) 0 – 10V (for PLC) |

FAQ
- Can I install analog programming later for most models?
Yes, analog programming can be installed later at the site for most models. Please consult XP Power Sales directly for more details or resources. - Are the analog signals isolated from the output potential?
Yes, the analog signals for voltage and current setpoints are isolated from the output potential via isolation amplifiers. Digital signals are isolated via optocouplers.
