Converter Operation - Victron energy Buck-Boost 25A Manual De Instrucciones

Input and output fuse
Use the following input and output fuse and cable intersection depending on the TS-Buck/Boost type:
Buck-Boost type
400
800
1600 *)
*) CAUTION! When using the 1600 type, a dynamo is required with sufficient load capacity to maintain the 120 A
flow
which the converter needs to be able to supply (at 100 A charging current).
First connect all GND cables to the converter, the battery and the chassis, and then only the positive (+) cable.
This is important because in the converter everything refers to GND.
When the two plus (+) cables are connected without GND, the potential difference between the plus (+) connections
ensures uncontrolled and unsecured currents!
Always check that the GND connection on the middle M8 connection is correctly connected.
The converter has no reverse polarity protection!

Converter operation

The Buck-Boost DC-DC converter operates on the principle of buck-boost.
This means that the input voltage may be both higher and lower than the set output voltage. The amount
of the charge current remains in both situations always fully under control.
A brief overview of possible conversions:
Buck-Boost type
400 charging current max.
800 charging current max.
1600 charging current max.
Charging current limiter
The output current is determined by the following factors:
Setting:
Temperature:
TSConfig application
The Buck/Boost converters can be configured extensively with TSConfig software. This software also includes a
monitor window, where real-time operation of the converter can be tracked.
The following image shows a screenshot of the TSConfig software:

100A
The maximum desired charging current (0..50A) is set via the USB connection
(with the Windows application TSConfig).
If the converter temperature comes close to the set maximum temperature, the charging
current is automatically limited. As a result, the temperature of the Buck/Boost inverter is
never inadmissibly high.
