In the Nominal Values group
the nominal values of the
output voltage, the maximum
current which the power
supply will source before it
switches into constant-
current mode, and
voltage rise and fall rates are
entered.
If the No Ramp at Switch Off
check box is checked, the
Ramp Down value is only
used if the nominal voltage is
changed. If the voltage is set
to 0, the channel ramps down
to zero and than switches off.
But using the OFF button to
switch off cuts off the output
voltage immediately.
The voltage regulation
parameters can be modified
with the Moderate
Regulation check box. If
unchecked, the standard (PI)
regulator is used. This is the
fastest regulation, but may
start ringing with wires to the
load longer than 1 meter.
In this situations
advanced (PID) regulator of
the Moderate Regulation
should be used.
If the load is connected with really long or high-inductance cable, the Slow Regulation check box
should be checked additionally. This increases the time constant of the I-Regulator.
The Control and Status group has buttons to switch the channel on or off. In case of any errors they
are displayed here, too.
The Supervision group contains all items which the microcontroller can observe. In case of
exceeding a limit, a dedicated action can be assigned to each item.
It is possible to
ignore the failure (not possible at max. terminal voltage, max power and max. temperature:
●
the power supply has to protect itself)
switch this channel off
●
switch all channels with the same group number off
●
switch all channels of the power supply off
●
The Identification group contains just a single item, the group number of the channel.
Many SNMP network commands can address a single channel (identified by the channel number) or
a group (identified by the group number), so it is possible to access different channels with only one
network message.
