Introduction
Intended use
The UPoB is an automotive universal power bridge that protects the connected system, such
as a XORAYA data logger, against voltage fluctuations and power failures. The device is able
to override the fluctuations for their duration of time. In case of a complete power failure, 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 (Universal Power Bridge)
power cable
COM breakout cable
user manual
USB driver
Check to ensure that the delivery is complete and all hardware components are in sound
condition. If the delivery is incomplete or supplied components are damaged, contact X2E
immediately. Do not use damaged components.

General safety instructions
The UPoB is only intended for use by qualified personnel. Read the user manual and espe-
cially this chapter thoroughly before operating.
CAUTION
Electric shock due to damaged components
Damages to the UPoB or the power cable can result in electric shock.
Check all components regularly for damages.
Only connect the UPoB if all components are undamaged.
CAUTION
Device damage due to vibrations, dirt or liquids
Excessive vibrations, dirt or liquids may result in malfunction or destruction
of the UPoB.
Avoid exposing the UPoB to excessive vibrations, dirt or liquids.
Keep the UPoB clean, especially plugs and sockets to ensure a reli-
able contact.
Never open the UPoB.
CAUTION
Device damage due to electrostatic discharge
Electronic components can be destroyed by electrostatic discharge.
Avoid touching connectors and connector pins.
Ground yourself before carrying the UPoB in your hands.
Operate the UPoB in an ESD-compliant environment.

Product overview
Identification
The identification plate and the buffer capacity label are located on the bottom side of the
UPoB.
The identification plate contains information about:
device type
serial number
configuration
date of manufacture / last modification
Configuration consists of three blocks:
product ID
product variant
hardware revision
This user manual applies to the Universal Power Bridge in hardware version 0302 and firm-
ware version 000307.
This label indicates the total capacitance of the integrated capacitors.

Pin Function
A1 KL31
A2 KL30
Switching on/off threshold
Vin ≥10.9 V: UPoB switches on
Vin ≤10.0 V: UPoB switches off (if capacitors com-
pletely discharged)
Charging threshold
Vin ≥11.3 V: capacitors charging
Vin ≤11.0 V: capacitors stop charging
The capacitors get their maximum charging voltage
of 10.0 V if the input voltage is 12.0 V or higher.
Mode-changing thresholds
Vin ≤10.0 V: UPoB switches into bridge mode
Vin ≥10.3 V: UPoB switches back into normal mode
(All values stated here apply to 0 A output load current. Please
refer to the appendix for thresholds of further currents.)

Configuration (B)
Switch Function when On
Trigger (1) sends trigger signal if the capacitance drops below the config-
ured trigger level (D)
Sleep (2) 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
Mode (3) mirrors the state of the input voltage at the output
deactivates the voltage output if:
the input voltage drops below 10.0 V
activates the voltage output if:
the input voltage rises above 10.9 V
Output (4) voltage output (F) activated
(All values stated here apply to 0 A output load current. Please refer to the appendix for thresh-
olds of further currents.)
Impact of the output switch on other modes
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.
