User Manual UPoB
Introduction
Intended use
The UPoB is an automotive universal power bridge that protects the connected system, such
as a X
to override the fluctuations for their duration of time. In case of a complete power f ailure, a
minimal voltage level is maintained until the connected system is shut down safely.
The UPoB is designed for industrial areas and must not be used in residential areas.
You may only operate the UPoB within the scope of the technical specifications provided in
this user manual. Additionally, the use in hazardous areas is not allowed.
Delivery contents

UPoB switches into sleep mode, where it does not send via
CAN and RS232, if:
the output load current drops below approx. 70 mA
UPoB wakes up if:
(Mode is On)
the output load current rises above approx. 80 mA
(Mode is Off)
the input voltage rises above 10.9 V

(All values stated here apply to 0 A output load current. Please refer to the appendix for thresholds of further currents.)
In order for the sleep and mode switches to work as described, the output
switch needs to be On. Otherwise, the UPoB cannot be woken up from
sleep mode if the mode switch is On, for example.

Discharging at high ambient temperatures can destroy the UPoB.
Reset (G)
This button covers the following functions:
restart the UPoB
acknowledge overcurrent event and reactivate voltage output
if connected via service interface (I), switch the UPoB into bootloader mode to per-
form a firmware update (further information in the corresponding chapter)
CAUTION
Device damage due to sudden voltage drop
time. The connected system can be damaged or destroyed due to the sudden voltage drop.
Shut the connected system down safely before pressing the reset
button.
Discharge (H)
This button discharges the capacitors. The Status-LED indicates the current status of the discharging process.
The discharge button is deactivated in sleep mode and when input voltage
or output current is present. An already started discharge process stops
when input voltage or output current is registered.
CAUTION
