96 W 24 VDC / 4 A Bicker UPS with Li-Ion battery

The UPSI-2406DP1 is an intelligent industrial DC/DC UPS backup power supply for equipment powered by 24 VDC. It offers a nominal output current of 4 A, power of 96 W, and an integrated Li-Ion battery with a capacity of 2.5 Ah / 37 Wh. It is designed for DIN rail mounting in a control cabinet.

The UPS is connected between an external 24 VDC power supply and the protected device. In normal mode, it passes the input voltage to the output while charging the integrated Li-Ion battery. The charging current dynamically adapts to the current consumption of the connected load.

When the input voltage fails or drops below a specified threshold, the UPS automatically switches to backup mode. It then powers the connected device from the battery and regulates the output voltage to 23.5 VDC.

All three models are intelligent DC UPS units for 24 VDC systems, mount on a DIN rail, and support USB, RS232, HID UPS, controlled shutdown, Reboot, Load Sensor, and other configurable functions. The main differences are the energy storage technology, available power, and backup time.

• UPSI-2406DP1: 24 VDC / 4 A / 96 W, integrated Li-Ion battery, 2.5 Ah / 37 Wh. At a current draw of 4 A, it provides approximately 12 minutes of backup time. It is suitable where several minutes of operation during a power failure are required.
• UPSI-2406DP2: 24 VDC / 4 A / 96 W, integrated supercapacitors, 5.73 kJ / 1.59 Wh. At 4 A, it provides approximately 30–35 seconds of backup time, but supports up to 500,000 charge and discharge cycles. It is particularly suitable for frequent short power failures.
• UPSI-2406DP3: 24 VDC / 6 A / 144 W, integrated LiFePO₄ battery, 2.5 Ah / 33 Wh. It offers a higher nominal current and power than DP1 and DP2 and, at 6 A, provides approximately 11 minutes of backup time.

The UPSI-2406DP1 is therefore particularly suitable for 24 VDC devices with current consumption of up to 4 A where several minutes of backup power are required. The UPSI-2406DP2 is more suitable for very frequent short power failures, while the UPSI-2406DP3 is intended for equipment with higher consumption of up to 6 A.

Yes. The UPSI-2406DP1 is a DC/DC UPS, not an AC/DC mains power supply. It requires an external 24 VDC power supply.

For full functionality at nominal load, the manufacturer recommends an upstream power supply rated at least 24 V / 5 A / 120 W. If you want to use the Dynamic Powerboost function, use a power supply rated at least 24 V / 6.25 A / 150 W.

The nominal input voltage is 24 VDC and the permitted input range is 22.5–30 VDC. In normal mode, the output follows the input voltage with a drop of up to 0.5 V depending on the load.

In backup mode, the UPS provides regulated 23.5 VDC regardless of the gradual battery-voltage decrease during discharge.

The switch from normal to backup mode takes less than 600 µs, or less than 0.6 ms. The connected 24 VDC device can therefore continue operating without a typical restart caused by a power failure.

No. The UPSI-2406DP1 does not support startup solely from the integrated battery without input power. It is put into operation by connecting a suitable external 24 VDC power supply.

The UPSI-2406DP1 contains an integrated Li-Ion battery with a nominal voltage of 14.8 V and a capacity of 2.5 Ah / 37 Wh. The manufacturer specifies a lifetime of up to 500 charge and discharge cycles.

Backup time depends on the consumption of the connected device, temperature, current charge level, and battery condition. At the nominal output current of 4 A, the manufacturer specifies an approximate backup time of 12 minutes at +25 °C.

Backup time increases at lower current draw. It may decrease at very high or low temperatures.

The manufacturer specifies an approximate charging time of 55 minutes at maximum charging current. The actual time depends on the battery discharge level, input voltage, and the current that the UPS simultaneously supplies to the connected device.

The UPS continuously monitors the battery condition and has undervoltage protection set to 10.8 V. When this limit is reached, it ends backup operation to prevent excessive battery discharge.

It depends on the required backup time and frequency of power failures. The Li-Ion battery in the UPSI-2406DP1 provides approximately 12 minutes of backup time at 4 A, making it suitable for bridging a longer power failure or safely shutting down a system.

The UPSI-2406DP2 with supercapacitors provides a much shorter backup time but supports a very high number of charge and discharge cycles. It is therefore particularly suitable for recurrent short power failures.

The UPS is designed for DIN rail mounting according to EN 60715. The manufacturer recommends vertical mounting on a horizontal DIN rail to ensure proper cooling by natural convection.

For adequate cooling, the manufacturer recommends leaving at least 20 mm of free space to the left and right of the UPS and at least 50 mm above and below the device. Ventilation openings must not be covered.

The UPS itself has an IP20 protection rating and is therefore not intended for unprotected outdoor installation. The manufacturer permits use indoors and outdoors only if the UPS is installed in a suitable enclosure that provides protection against water, fire, and electrical hazards.

The operating temperature of the UPSI-2406DP1 is 0 to +50 °C. The storage and transport temperature is −20 to +50 °C. Available battery capacity and backup time can change at very high or low temperatures.

The UPS dimensions are 63 × 120 × 100 mm without front connectors and the DIN rail mounting bracket. The weight is approximately 0.6 kg.

No. The UPSI-2406DP1 is not intended for series or parallel connection of multiple UPS modules. Each backup power supply must be designed separately for a specific 24 VDC load.

The nominal output current is 4 A, which corresponds to a power of 96 W during normal operation. In backup mode, the manufacturer specifies a nominal power of approximately 94 W at a regulated output voltage of 23.5 VDC.

Dynamic Powerboost enables the UPS to temporarily provide a current higher than the nominal 4 A. The output current can increase to 4–6 A, or up to approximately 144 W in normal mode.

The duration is not fixed at 58 seconds for every load. The UPS evaluates the energy drawn, and the maximum Dynamic Powerboost time is 58 seconds. Therefore, always design equipment for a continuous nominal current of 4 A.

Yes. The UPS supports a short-term SFB current of up to 30 A for 5 ms. This value is intended for very short current peaks and cannot be considered a continuously available output current.

The UPS has input reverse-polarity protection when connecting a switched-off device and output protection against overcurrent and short circuit. The output is also resistant to no-load operation.

When the permitted current is significantly exceeded, the UPS disconnects the output quickly. However, input reverse-polarity protection does not apply when connecting a reversed-polarity input during active backup operation, so correct polarity must always be verified before connection.

Basic operating states are indicated by a status LED. The UPS can be connected to a computer via USB. Supported operating systems can recognize it using Plug & Play as a HID UPS or HID Battery class device without installing a separate driver.

UPS Gen2 Configuration Software is available for parameter settings and firmware updates. UPScom can be used for continuous monitoring, controlled shutdown, email notifications, or running custom scripts.

The UPSI-2406DP1 supports USB 2.0 with a USB-B connector, the RS232 serial interface, and HID UPS. RS232 uses a 9-pin D-Sub connector and a transmission rate of 38400 baud.

A potential-free relay contact for power-failure signalling is also available.

The potential-free relay contact is primarily intended for signalling an operating status, such as a power failure. The contact is rated for a maximum of 24 VDC / 1 A or 125 VAC / 0.5 A. The NO or NC function can be configured by software.

The Load Sensor monitors the current drawn by the connected device. If consumption falls below a configured value after controlled shutdown of a computer or another system, the UPS can evaluate this condition as completed shutdown and subsequently end backup power supply.

This prevents unnecessary battery discharge after the connected device has been switched off.

Yes. Via USB and UPScom software, the UPS can initiate a controlled computer shutdown during a power failure. For example, shutdown delay, maximum backup time, minimum battery state before system startup, or execution of a custom program or script before shutdown can be configured.

It is necessary to verify that the specific computer can complete all required operations within the available backup time.

The Reboot function helps automatically restore operation of the connected system after input power returns. For an industrial computer, the BIOS and operating system must also be configured correctly so that it can start automatically after power is restored.

The UPS is suitable, for example, for industrial computers, machine controllers, communication equipment, network devices, measuring devices, and other electronics powered by 24 VDC that must continue operating or shut down safely during a power failure.

The manufacturer specifies it for professional use, for example in industrial control, communication, and measurement technology. It is not intended for applications where its failure could directly cause serious injury or endanger human life.
