Bicker UPSI-2406DP2 · backup power supply with supercapacitors
Protect your 24V devices and data from power outages
The Bicker UPSI-2406DP2 keeps your 24V devices running during a brief power outage. It provides a rated output of 96 W and 4 A. Energy is stored in built-in supercapacitors that recharge quickly and withstand up to 500 000 charge and discharge cycles. At a load of 4 A, backup time is approximately 30–35 seconds. This can provide time to save data or shut down safely, provided the connected device can complete the process within the available time. The compact unit mounts on a DIN rail in a control cabinet. FOXON will help you choose the right unit and arrange worldwide shipping.
How long do you need to keep your devices running during an outage?
Tell us which devices you want to back up and for how long. If you know their power consumption in watts, include it; we will help you choose a suitable backup unit and power supply.
Reliable backup for industrial automation
An uninterruptible power supply, or UPS, helps protect industrial computers, machine controllers (PLCs), network devices and measuring instruments against brief power outages. It switches to supercapacitors in less than 600 µs, or 0.6 milliseconds. In backup mode, it regulates the output to 23.5 VDC. Check that this voltage, switching time and available backup time suit your connected devices.
Supplies connected 24V devices with a rated current of 4 A. During supercapacitor operation, it maintains an output of 23.5 VDC.
USB type B connects the unit to a computer. RS232 with a D-Sub connector is available for serial communication. A potential-free relay contact can also signal a power failure.
The built-in supercapacitors withstand up to 500 000 charge and discharge cycles. They provide maintenance-free energy storage, suitable for frequently recurring brief power outages.
For new control cabinets and upgrades to existing equipment
Use the UPSI-2406DP2 when building a new control cabinet or adding backup power to an existing machine. It helps protect devices powered by 24 V against short outages and voltage fluctuations.
A machine controller, industrial computer or PROFINET or Ethernet network switch can therefore ride through a brief outage without an unnecessary restart. If the outage lasts longer, backup power can provide time to save data or bring the machine to a safe stop – always within the available backup time. DIN rail mounting makes installation in a control cabinet easier.
Supercapacitors: ready for frequent brief power outages
Supercapacitors store electrical energy differently from batteries. Their main advantages are fast charging and a high number of repeated uses: they withstand up to 500 000 full charge and discharge cycles. The technical abbreviation EDLC stands for electric double-layer capacitor. Built-in electronics control charging and discharging; cell balancing helps keep the cell voltages balanced.
The UPSI-2406DP2 has a nominal energy capacity of 5.73 kJ, equivalent to 1.59 Wh. Its usable capacity is 3.88 kJ, equivalent to 1.08 Wh. It is primarily suited to brief, frequently recurring outages; choose a suitable battery UPS for longer operation without the main power supply. Actual service life depends on temperature and operating conditions.
How long will your devices keep running during an outage?
The UPSI-2406DP2 provides approximately 30–35 s of backup at an output current of 4 A. The graph shows how backup time increases at lower loads; the vertical axis is in seconds and the horizontal axis in watts. The reference temperature is +25 °C. Actual time depends on charge level, supercapacitor condition, temperature and UPS settings. Add up the power consumption of the devices to be backed up and allow a margin for completing work or shutting down.
View the charge level and settings in your browser
UPScom lets you view the current supercapacitor charge level and configure how the backup power supply responds to an outage. The program is installed on a computer and operated through a web browser. Versions are available for Windows and Linux.
When connected via USB, supported operating systems recognise the device as a UPS without an additional driver. The technical designation is HID Power Class. UPS Gen2 Configuration Software lets you change settings and update the firmware, the unit's internal control software, in Windows. Use UPScom for continuous monitoring, email notifications and running your own program before the computer shuts down.
- monitoring current draw in mA and detecting when it drops below a set threshold,
- shutdown delay, maximum backup time and minimum charge before startup,
- email notifications in case of loss of connection, power outage or system shutdown,
- safe shutdown and, if needed, running a custom script — a prepared sequence of commands — before the computer switches off.
Safe shutdown and automatic computer restart
During a power outage, the UPS notifies the connected computer. With the correct settings, the computer can save data, complete predefined tasks and shut down safely. It must finish within the available backup time: at 4 A, this is approximately 30–35 s. Once power returns, the automatic restart function, called Reboot, can be used. Also check the operating system settings and the industrial computer's (IPC's) automatic power-on settings.
Connections are available via USB type B and the RS232 serial interface. If you want to send data to a machine controller or another system, check its communication support and the required software. A serial connector alone does not guarantee compatibility.
Connections for computers, machines and power failure signalling
Practical features that help in real operation
The UPSI-2406DP2 monitors the load of connected devices and the supercapacitor charge level. Depending on its settings, it can bridge a brief outage or provide time to finish work and shut down, provided sufficient energy is available.
Charging takes approximately 4 min 30 s at the maximum charging current. The time varies with input voltage, connected load and charge level. At higher loads, supplying the devices takes priority and charging is reduced.
Shutdown can be configured according to the remaining charge, maximum permitted backup time, a schedule or a drop in load. The UPS also supports a shutdown command via an external signal. The connected computer or machine controller must complete the necessary tasks before power is disconnected.
Dynamic Powerboost allows a temporary current draw of 4–6 A. It is available from firmware 2.2.1. The UPS continuously evaluates the energy drawn over the last 58 s; this does not mean that 6 A is continuously available or that 58 s is guaranteed at maximum current. Use the rated 4 A for system design and check the required backup time as well.
Immunity and protection functions
The UPSI-2406DP2 operates at −20 to +65 °C. Certifications: ETL UL 61010-1 / UL 61010-2-201, CSA C22.2 61010-1-12 / CSA C22.2 61010-2-201 and CB Scheme IEC 61010-1 / IEC 61010-2-201. The aluminium housing has an IP20 rating and measures 63 × 120 × 100 mm, excluding front connectors and the DIN rail bracket.
Allow space around the unit for cooling. For effective cooling, use vertical mounting on a horizontal DIN rail, with 20 mm clearance on the left and right and 50 mm above and below the unit. Do not cover the ventilation openings. Very low or high temperatures may reduce backup time.
Immunity to short sequences of fast electrical interference pulses according to EN 61000-4-4: 2 kV. Surge immunity according to EN 61000-4-5: ±0.5 kV between L–N conductors and ±1 kV between L–PE/N–PE. Criterion A applies in both cases: normal operation within the specified limits. The unit meets conducted and radiated emission requirements according to EN 55016-2-3.
The output has overcurrent and short-circuit protection. Input reverse-polarity protection applies when connecting a unit that is still switched off; it does not protect against reversed input polarity during backup operation. In the event of a fault, the output disconnects and the LED indicates the status. Always check the wiring before commissioning.
The UPS lets you set the power supply duration after an outage and detect a low load from connected devices. Once work is complete, it can disconnect the output and conserve the remaining energy. Energy storage undervoltage protection is also included.

Frequently Asked Questions
How long can the UPSI-2406DP2 keep a device running during an outage?
At a current of 4 A, backup time is approximately 30–35 s under reference conditions of +25 °C. Backup time increases at lower loads. Charge level, temperature and settings also affect it. Send us your devices' total power consumption and the required operating time during an outage – we will help you choose.
How do I connect the UPS to a computer or control system?
You can connect to a computer via USB type B; a supported operating system recognises the unit as a UPS (HID-UPS). Another option is RS232 with a D-Sub connector. For a custom control system, check the communication protocol and software. A relay contact can also signal an outage.
Can the unit be started manually without input power?
This model does not support manual startup from its energy storage without input power. Commissioning begins by connecting a suitable power supply. Automatic backup during an outage and restarting when power returns are separate functions.
What happens when current draw is low or the energy storage is discharged?
The UPS detects when the current draw falls below a set threshold. After connected devices have shut down safely, it can disconnect their power and prevent unnecessary consumption of the remaining energy. The energy storage also has undervoltage protection.
Should you choose a UPS with a battery or a supercapacitor?
A LiFePO₄ battery is suitable for longer operation during an outage. A supercapacitor is a different way of storing electrical energy: it is mainly suited to short, very frequent outages. The main factor when choosing is how long your devices need to work without the main power supply.
Can this UPS safely shut down any computer?
Not automatically. Measure the power consumption and the time needed for the specific computer to save data and shut down. At 4 A, the UPSI-2406DP2 provides approximately 30–35 s of backup. If you need more time, choose a suitable battery version. Test the settings and the entire procedure in your application.
What can the relay contact switch?
The potential-free contact is used for operational signalling. The contact is rated for 24 VDC / 1 A or 125 VAC / 0.5 A. Signalling by closing or opening the contact (NO/NC) can be configured in software. Observe the applicable electrical limits and insulation requirements when wiring it.
