depending on the load, up to the kV Setpoint. The
operation is different than the voltage regulation
mode in that, when the kV Setpoint is reached,
there is no “over-voltage” function and the unit
maintains the output voltage at the setpoint and
allows the current to drop. It stays in this mode
until the load changes such that the current in-
creases up to its setpoint, then it limits at the set-
point and the voltage drops. The big difference
between voltage and current regulation is that the
Current Setpoint is used to set a limit and not an
Over Current shutdown point. The actual Over
Current threshold is set 30% (SW7-5 OFF) above
the Current Setpoint so that in a dynamic situation
where the current can actually rise above the limit
point, the Over Current function is still active.
VERSION 3.8 SOFTWARE
This version adds some switch settings for the
new HP505 cascade. The HP404 settings hav-
ing zero voltage corrections factors (“K”) may be
used for HP505. For voltage correction using the
HP505, switches must be set per Figure 6. Note
that this changes the function of SW7-1 from node
addressing to cascade selection. It is not needed
for node addressing.
VERSION 3.9 SOFTWARE
This version adds appropriate switch settings for
the new RP404 cascade. These can be found
in Figure 6.
