UPSI-2412D

Intelligent DC-UPS / 240W / 24V 10A / DIN Rail version / DC-DC

Avoid system failures and data loss!
Modular DC emergency power supply with 10A protects against power failure, voltage drops and flicker

The intelligent DC UPS UPSI-2412D for flexible system integration reliably bridges power failures and faults, so that the uninterruptible 24 VDC power supply with up to 10A is guaranteed at the output at all times.

In normal operation, the UPSI-2412D forwards the DC input voltage directly to the output, charges the connected energy storage device in parallel and monitors all relevant parameters, currents and voltages. In the event of a voltage drop or power failure, a MOSFET disconnects the input within a few microseconds and the connected load is supplied without interruption from the energy storage device and the UPSI-2412D provides a constantly regulated DC output voltage.

Flexible use of suitable energy storage

So that the UPSI-2412D can be used flexibly with different storage technologies, three charging methods with individual adjustment of the end-of-charge voltage are implemented: Constant Current, Constant Voltage and Constant Power. The integrated microcontroller (µC) recognizes the type and data of the energy storage so that the charging and discharging parameters can be individually adjusted.

Supercaps (ultracapacitors)
In the area of short and medium bridging times, with the BP-SUC series we offer absolutely maintenance-free supercaps as highly efficient and particularly long-lasting energy storage devices with more than 500,000 charge and discharge cycles.

LiFePO4 battery cells
Lithium-ion technology with high energy density is ideal for longer bridging times. Our high-performance battery packs of the BP-LFP series impress in safety-relevant applications with a high cycle stability (6,000 charging and discharging cycles) and an integrated battery management system (BMS).

Lead batteries
With the UPSI-2412D it is also possible to use selected lead-acid battery storage systems - please contact us, we will be happy to advise you!

Plug & Play for quick and easy installation

The UPSI-2412D has an integrated USB interface for connection to an IPC system and is recognized directly by the operating system as a UPS - without additional drivers or software installation.

Intelligent PowerSharing Function

On the input side, this implemented function ensures that the upstream AC/DC power supply does not have to be oversized, but that the input power is kept constant and appropriately distributed to the load and battery charger. This means that if the load at the output is low, more energy flows into the charger and vice versa.

Battery start function

For mobile applications, the UPSI-2412D has the option of starting the supplied application with a maximum load current of 7 A from the battery, without a mains-side power supply being available or connected. To do this, the 'BS' button is pressed for more than 2 seconds. We recommend the LiFePO4 battery pack BP-LFP-2725 for this purpose.

Relay contact for PowerFail

The functionality and behavior of the 2-pin relay connection in the event of a power failure can be defined using the 'UPSGen2 Configuration' software: 'Normally Open', 'Normally Closed' or 'Shutdown Pulse'. When the relay closes, the resistance between the two pins is ⁓ 0 Ohm, otherwise the contacts are 'Open Load'.

Minimum load detection

In the 'UPSGen2 Configuration' software, the minimum output current to the DC load in UPS battery operation can be set and monitored via the load sensor. If the load at the output falls below this limit value, the energy storage device is automatically disconnected from the charging and control unit after 10 seconds, so that no unnecessary and gradual discharge of the energy storage device can take place. The DC UPS can also be switched off in a defined manner.

'UPSGen2 Configuration' software –
Extended functionality and monitoring

The free 'UPS Gen2 Configuration' software is available for download and is used to setup and parameterize the DC UPS system as well as for real-time monitoring. The UPS and battery status displays include all relevant voltages, currents as well as battery temperature, state of charge (SOC), runtimes and cycles. The pre-programmable parameters include load sensor (mA), shutdown delay, maximum backup time, minimum load capacity before system start, ignition timer and restart delay. Self-sufficient operation is then possible with the set values.

Timer function for controlled system shutdown according to the time specified

The new "Shut Down OS in" parameter can be used to set the time until the computer system is shut down and switched off in the event of a power failure. In addition to the operating system setting with regard to „State Of Charge“ of the energy storage device ("Shut Down OS at SOC"), the new function can now be used to define a specific time for the controlled shutdown in UPS backup mode.

Shutdown & reboot function for IPC systems

In the event of a ‘PowerFail, the DC UPS signals the failure of the supply voltage via the integrated interface, so that a controlled shutdown of the computer system is initiated and valuable data is saved. The integrated reboot function of the DC UPS automatically initiates the restart of the supplied IPC after the supply voltage has returned, without the need for costly on-site intervention by a service employee, e.g. with completely self-sufficient computer systems in inaccessible locations.

DC UPS systems for maximum reliability of 24VDC applications

In the area of uninterruptible power supply, our DC UPS systems can be used in a variety of applications for a wide variety of industries and fields of application: Industry 4.0, automation, medical and laboratory technology, transportation, traffic monitoring, energy, communication, vending, POS / payment systems, security technology, mobile systems and much more.
