Operating the device
11.3 Notes & limitations
•
If the output condition shall not be restored to ON after the
device is powered, disable this feature. See section „7.1.
Defining operation parameters“
, item „Output condition after
‚power on‘“.
•
During remote control via an analog interface the preset
values of current and power (see above) can not be restored
after switching the output off, because the set value input
PSEL and CSEL constantly set new values and thus the
preset values in OFF mode will be the last one that were
present on the inputs.
•
If PV mode is activated in the setup (menu „Options“), the
function manager (SEQ) is not accessible.
12. HS - High speed ramping
The power supply features an integrated HS feature which pro-
vides improved dynamics of the output voltage due to reduced
output capacities.
This is a permanent modification which can not be deactivated
and will effect some of the standard technical specifications.
See table on the next page.
Voltage overshoot!
Power supplies with High Speed option can produce
very high voltage overshoots on the output, if the load
changes. The electric strength of connected loads must
be observed!
12.1 Restrictions
•
Remote sense operation and series connection are not avail-
able and not allowed!
•
The fall time t

is load depending and can be calculated by
the user from the given output capacity
•
In case the given time and power dissipation for permanent
pulsed operation are not adhered, the warranty claim expires

Recommended minimum output voltage resp. minimum actual
power the device should be operated with. Below these values
the output ripple is expected to be even higher than stated in
the table above.
