B Introduction and description
Read carefully before initial operation!
This manual shall help the user to get familiar with the product and its components and features. It shall pro-
vide information as accurately and completely as possible.
The manual as well as all documents has to be read and followed strictly before installation. Otherwise in cer-
tain situations warranty and guarantee can be cancelled partly or completely. Any liability on the part of Bicker
Elektronik is excluded for possible existing errors as well as non-compliance with the instructions for use and
installation.
B1 Description of the product and its functions
The UPSI-2412 (hereinafter also called UPS) is a DC/ DC UPS system with numerous digital features and high
performance. The UPS can be operated with different energy storage devices (hereinafter also called batte-
ry(s)), which are different in technology, capacity and chemistry. Only energy storage devices made by Bicker
Elektronik are to be used, due to the charging settings are made according the recognization of the used bat-
tery type. The primary use of the UPS is to secure the supply during power failures and/ or voltage fluctuations.
The application which should be protected is connected to the output of the UPS.
The UPS requires a rated dimensioned power supply of 24V DC at the input. After the input voltage is applied,
the UPS works in normal mode automatically. The input voltage is passed through to the output and the
connected energy storage device is charged simultaneously. The charging current depends dynamically on
the load current at the UPS output. The green status LED lights up continuously when the UPS is in this state.
In the event of a voltage drop or a voltage fluctuation of the input voltage (below undervoltage limit),
the UPS is switched to battery mode (also backup mode). In this state, the application at the UPS output
is supplied via the energy storage device. The backup time (also buffer time) depends on the used ener-
gy storage, the value of the output current and the software settings of the UPS. An important feature is
that the output voltage in battery mode is always regulated to 23.5V DC and does not decrease as the
voltage of the energy storage device drops. If the UPS operates in battery mode, the status LED is slowly fla-
shing (1Hz flashing). When the UPS is used with LiFePO4 battery and it is discharged completely in battery
mode, the recharging has to happen as soon as possible.
When the input voltage returns, the UPS is automatically switched back to normal mode and charging of the
energy storage device is continued.
The UPS can also be used for user-initiated shutdowns of the supply voltage or cycles. Application examples
are the replacement of larger batteries in vehicles in which the electronics should continue to be supplied, the
opening and closing of safety valves after a malfunction or the shutdown of a system.

Revision 1 17
F General Data
F1 Installation advice
Installation and operation of this device is only allowed to be executed by a qualified
electrician! The application has to be separated from any power during the mounting process.
Wires have to be connected safely and must not have contact with sharp edges. Pay attention
to correct polarity! Before commissioning, check all the connections for correctness!
F2 Convection and installation position
When installing in the overall system, it has to be ensured that
the required distances to neighboring parts and boards are main-
tained. Sufficient ventilation holes or open ventilation areas should
be provided during installation in order to avoid air congestion or
the like. The device can optionally be installed in the system with
suitable heat conducting pads (gap pad/ gap filler) in order to
compensate for temperature increases of the components due
to closer/ narrow placement to neighboring components. This is
recommended on the bottom side in the area of the converter
(choke L1, MOSFETs Q3-Q6, Q39) and in the input area (choke L2).
The functional grounding of the UPSI-2412 is provided on the
input side (VIN – ). So that the EMC filter on the circuit board can
work correctly, the output GND (VOUT) should not be connec-
ted directly to the input GND (VIN – ). The mounting hole next to
socket X1 is connected to VIN – , the remaining mounting holes are
isolated.
It is recommend, installing the board vertically in the overall
system with the input/ output socket X1 pointing upwards. This
installation position favors the heat dissipation of the circuit board
hot spots in the area of X1 and the converter.
The following distances to neighboring devices
are recommended:
Top side circuit board:
–>Neighboring component: 30 mm min.
Bottom side circuit board:
–>Neighboring component: 10 mm min.
Left/right:
–>Neighboring component: 4 mm min.
