Handling
Powering the device
The device does not feature a power switch. When
connecting it to mains, it is immediately ready to
work.
After switching mains off the device stores the last
state (selected mode, output condition) in order to
restore it automatically at the next start. Thus it can
continue to work after an interruption like a blackout
etc.
Charging a battery (only models up to 65V)
In order to use the battery charging feature, the
pushbutton „Output Voltage Range“ is used to select
one of the xed voltages while the output is switched
off. For example, at a 32V model the 24V selection
is dedicated to trickle charge and the 27V to normal
charge.
Charging works with either constant voltage or with
constant current, but without temperature compen-
sation and without a charging prole. Thus it is only
recommended for common lead batteries.
In case it is required to limit the charging current, the
device has to be controlled remotely via the analo-
gue interface. The CSEL input can control the output
current within 0...100%.
Adjusting the output voltage
Models with up to 65V output voltage feature a selec-
table voltage range, that is adjustable with the built-in
trimmer. This is a 10-turn trimmer and a complete
rotation from left stop to right stop corresponds to
0...100% nominal voltage.
At models with more than 65V the output voltage is
seperated into three selectable voltage ranges, each
approximately 1/3 of the nominal voltage. For details
see the „Technical specications“. The built-in trimmer
is a 10-turn type and a complete rotation from left stop
to right stop corresponds to the selected range.
Switching output on or off
The pushbutton „Output On“ is used to switch the
power output on or off, if not inhibited by an error
(OVP or OT) or the device being in remote control.
The voltage set by the trimmer or the selected xed
voltage at models up to 65V will then be put out im-
mediately.
The output can also be switched off at any time via
pin 8 „Rem-SB“ of the analogue interface and then
on again.
Attention! The pin overrides button „Output On“.
When the output is switched on, the LED „CC“ will
indicate constant current operation (LED is on) or
constant voltage operation (LED is off).
Selecting a voltage range
The pushbutton „Output Voltage Range“ is used to
select the output voltage ranges. The output has to
be off in order to select the voltage range.
Remote control
Set values can be put in externally via the pins VSEL
and CSEL and with analogue voltages of 0...10V.
The power output values are put out as monitor si-
gnals VMON and CMON in a range of 0...10V.
In order to control the set values remotely, the „remo-
te“ control has to be activated rst. This is done by
pulling pin 7 „Remote“ to low. If required, one of the
set values can be bridged to the reference voltage
VREF and will thus be 100%.
Remote control is indicated by the LED „External“.
For pin assigment of the analogue interface see next
page.
Application examples for the analogue interface
Remotely switching output on / off
Digital input (DI)
The input can be used to switch off the device output
at any time. After this, switching it on again is only
possible by releasing the contact or switch.
The contact/switch on pin 8 overrides button „Output
On“.
Switching to remote control by pin 7 is not required.
