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-2406IP-38AC (hereinafter also called UPS) is a AC / DC UPS systems with numerous digital features and
high performance. The UPSI-2406 is combined with an upstream AC/DC converter as well as an already inte-
grated LiFePO4 energy storage. 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 device has IP65 protection and has been developed for the specific use under extreme conditions.
The device requires a rated dimensioned AC voltage (100…240 V AC nominal) at the input. After the input
voltage is applied, the UPS works in normal mode automatically. The output is activated and the integrated
energy storage device is charged simultaneously. The input current is dynamic and depends on the load
current at the output and the current battery charge current. The green status LED at the bottom of the device
lights up continuously when the UPS is in this state.
If the input voltage drops below the lowest nominal value, the UPS is switched to battery mode (also back-
up 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 value of the output current (= load current) of the UPS.
An important feature is that the output voltage in battery mode is always regulated to approximately
23.5 V 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 flashing (1 Hz flashing). After having been operated completely in
battery mode, the recharging of the LiFePO4 battery has to happen within two weeks.
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.
A pressure compensating element on the bottom side of the housing prevents condensation inside the device.
