Deutronic DBL - Operation Mode; SUPPLY MENU: Power Supply Mode; CHARGE MENU: Battery Charging Mode

Deutronic DBL Manual (MPC4) - 14VDC - EN - 10 / 20 - 10 / 2006
5) Operation Mode
5. a) SUPPLYMENU – for power supply mode
Parameter Nominal value Value / Setting range / Information
Output voltage U 2 to 15,5 V [*]
Note: The limiting value for max. voltage 15,5V is a SAFETY LIMITATION
and can be adjusted due to long load cables.
See 5. c)DEVICEMENU – for device specific parameter setting

max
[*] depends on charger version (for details see data sheet)
Note: I
max
is depending on the preset voltage
and limited via a dynamic temperature control
[*] Note: Should the preset power of the battery charger be higher than the nominal power of the device,
the DBL adjusts automatically the limiting values, if needed.
Example: If the voltage is in the threshold and the output voltage U is heightened further, so automatically the max.
current I
max
is reduced and vice versa.
5. b) CHARGEMENU – for battery charge mode
Parameter Value Setting range / Information
Charging voltage U U
tri
to U
max
(U = typ. 14,2 .. 14,8 V)
Note: In chapter 5. c) DEVICEMENU the max. charging voltage U
max
is fixed (standard value is 15,5V)
Trickle voltage U

to U (U
tri
= typ. 13,2 V)
Note: Limiting values for the trickle charge voltage are starting voltage and
adjusted charging voltage.
Starting voltage U
min
5V to U
tri
(U
min
= typ. 5 .. 11,5 V)
Minimum voltage of the battery - this defines the voltage
limit which must be exceeded by the battery before starting to
charge.
Note: The starting voltage is a SAFETY FUNCTION which ensures that
for charging really an acceptable battery is connected.
Due to safety reasons in operation mode AUTOMODE no batteries are
accepted which have a lower voltage level than 11,0VDC. However should
a deep discharged car battery be charged, the operation mode has to be
set from AUTOMODE to CHARGEMODE.
