Blink output on backup
When this option is enabled, during backup, the output voltage switches on/off periodically with the
timing defined on "Blink output on backup Ton" and "Blink output on backup Toff" (see no. 42 and no.
43 in section 6.2). This function may be used on illumination application where is necessary to inform the
person in the building that the lighting is running on batteries.
5.2
DC-DC mode
The UPS module can be used as a high performance DC-DC converter. An example of DC-DC connection
is given on Figure 11.
Any voltage between 10 V to 55 V can be converted to any voltage between 10 V to 55 V (step-up and
step-down operation) with up to 20 A input or output current.
Input and output are protected against over current with user settable limits. See section 5.3 for more
details.
When used as a DC-DC converter, the input supply must be connected to the battery connector as shown
on Figure 11.
