Modular 24V emergency power supply for fail-safe systems in industrial, medical and process technology

The intelligent DC emergency power supply UPSI-2412 from Bicker Elektronik in combination with suitable LiFePO4 or Supercap energy storage devices, reliably bridges power failures and brownouts, so that the uninterruptible 24 VDC power supply of process-relevant systems is guaranteed at all times. These include sensitive control and regulation systems, embedded IPCs, gateways, motors, actuators, sensors, monitoring and safety technology. In this way, costly system downtimes and data loss can be effectively avoided. The DC UPS board UPSI-2412 is designed for flexible open-frame system integration in customer-specific applications and enables individual emergency power supply solutions for long-term use in the fields of Industry 4.0, medical and laboratory technology, renewable energy, control and regulation technology, safety, vision and inspection systems.

DC emergency power supply with regulated output voltage

In normal operation, the UPSI-2412 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-2412 provides a constantly regulated DC output voltage.

Intelligent PowerSharing function

This implemented function at the DC input ensures that the upstream AC/DC power supply does not have to be overdimensioned, but that the input power is kept constant and distributed accordingly to the load and the charger. This means that when there is a low load at the output, more energy flows into the charger and vice versa.

Flexible use of suitable energy storage devices

To ensure that the UPSI-2412 can be used flexibly with different storage technologies, three charging processes with individual adjustment of the end-of-charge voltage and a charging current of up to 4.5A are implemented: Constant Current, Constant Voltage and Constant Power. The integrated microcontroller (µC) recognizes the type and data of the Bicker energy pack, so that the charging and discharging parameters can be individually adjusted.

Supercap energy storage – fast charging and absolutely maintenance-free

In the area of short and medium backup times, Bicker Elektronik offers with the BP-SUC series absolutely maintenance-free Supercaps as highly efficient and particularly long-lasting energy storage devices with more than 500,000 charge and discharge cycles. Supercaps (EDLC) are based on electrophysical principles and are charged and ready for use within a very short time. Under comparable operating conditions, Supercap energy storage devices have a service life that is up to ten times longer than classic lead-acid batteries. Energy packs with Supercapacitors also impress with their high current carrying capacity, power density and reliability.

LiFePO4 battery packs – particularly safe and durable

Lithium iron phosphate technology with a high energy density is ideal for longer backup times. The high-performance battery packs of the BP-LFP series convince in safety-relevant applications with a particularly stable battery chemistry, high cycle stability and a long service life of at least 10 years. The integrated battery management system (BMS) with cell balancing ensures that all cells are charged evenly so that the full capacity of the battery pack can be used over the long term. In contrast to lead-acid batteries, high-quality lithium iron phosphate cells have an approx. 15-20x longer service life and cycle stability. In addition, 100% of the full nominal capacity of the LiFePO4 battery pack can be drawn continuously. Conventional lead-acid batteries have significant limitations in terms of DoD (Depth of Discharge) and number of cycles. When calculating the TCO (Total Cost of Ownership) over the entire period of use of at least 10 years, there is a clear cost advantage compared to lead-acid batteries, especially since the effort for maintenance and battery replacement for LiFePO4 is eliminated during this period.

Battery start function

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

Plug & Play for quick and easy installation

The UPSI-2412 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.

‚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.

Potential-free 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.

Quality, safety and reliability – Made in Germany

The company Bicker Elektronik grants a three-year warranty on the DC-UPS UPSI-2412, as well as a long-term availability of at least 5 years. This provides optimal investment protection for applications with a long runtime. System developers also benefit from personal design-in advice and first-class service and support from the power supply specialists at Bicker Elektronik. On request, the development engineers implement customer-specific special solutions and also offer extensive laboratory and measurement services for complete customer systems.
