B1 Description of the product and its functions

The UPSI-1208IP-11U and UPSI-2406IP-12U (hereinafter also called UPS) are DC / DC UPS systems with nume-
rous digital features and high performance. The UPSI-1208 or UPSI-2406 is combined with 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 devices have IP65/67 protection and have been developed for the specific use under extreme conditions.
The UPS requires a rated dimensioned power supply of 12 V DC or 23.5 V 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 integrated 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 energy
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 12 or 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 fla-
shing (1 Hz flashing). After having been operated completely in battery mode, the recharging of the LiFePO4
battery 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.
A pressure compensating element on the connection side of the housing prevents condensation inside the
device.
