Programming/Monitoring V/C Analog Interface (Ureg /Ireg) (Umon/Imon)
The standard programming of the HSEUiREG Series is an analog interface. The output voltage is linearly
proportional to the adjusted analog control signal. If the control signal 0V and/or 0A applies the power supply
delivers 0V at the output. The power supply is already working from 0V output voltage and low load with high
precision.
The monitor signal is analog linear to the output voltage. The monitor signal for current and voltage is the real
value that is measured directly at the output of the power supply. If a sense line is connected to compensate for
the voltage drop across the load lines, the monitor signal is exactly the value that is measured at the connection
point of the sense line. The description of the power supply in the sense operation is carried out in a separate
section.
The analog inputs and outputs are non-floating. The mass is connected to the DC negative output.
The adapter provides the ability to select the desired input / output via a DIP switch. The burden of the control
voltages is 1M
Ω
. The burden of the current interface is 500
Ω
. The latency to full compensation of V/C on the
interface from 0-100% is 15ms for all HSEUiREG models.
If the power supply is operated with a low load, the down-programming time up to the desired set point may be
very long. The power supply has large built-in capacitors and an enormous energy reserve. A similar effect
occurs by skidding input energy, which is not easily removed from the power supply. A PowerSink (PS) modul
can be ordered as an option for each HSEUiREG power supply unit. The PS option is used for fast down
programming and the degradation of skidding energy fed. The option must be equipped in the factory.
For further information about the PS option, please refer to the technical details in a section PS-option.
Compensation of Load Line Drop Voltage (Sense +/-), standard operation mode
The HSEUiREG power supply has a Sense Mode to compensate for the voltage drop over long load lines. The
compensation amounts to a maximum of 2V per load line. Under certain circumstances, it can be expected to
apply more complicated external interference suppression. If sense is not used, Sense + and Sense - shall
necessarily be connected by short bridges to AUX + and AUX - (factory setup). Make sure that +/- connections
are matching!
WARNING!
Reverse polarity of the sense lines can cause damages to the power supply unit.
Sense operation: Remove the bridges between Sense +, Sense -. Connect the sense lines directly to the load.
Pay attention to the polarity of plus and minus of the load to prevent damage to the power supply. To avoid
interference, twist the sense lines. To reduce inductive effects, we recommend that the load lines position is
close to each other. To supply a pulsating load, the use of an electrolytic capacitor and a cermic capacitor has
proved. The internal Over Voltage Protection (OVP) of the power supply controls the DC power directly to the
DC output terminals. In case of an error the OVP acts automatically (see OVP values corresponding table).
The sense terminals are directly connected to the power outputs.
