Outdoor AC/DC UPS for mast mounting protects 24V security and measurement technology

Emergency power supply solution with LiFePO4 battery technology

Bicker Elektronik, Donauwörth, Germany, presents the AC/DC UPS UPSI-2406IP-38AC in combination with the mast mounting set PSZ-1100, a robust and reliable emergency power supply solution for sensitive outdoor safety and measurement technology. In case of failure, shutdown or fluctuation of the AC supply voltage, the outdoor UPS ensures uninterruptible power supply of sensitive 24VDC applications, such as measurement and control technology, sensors, lighting, cameras and security technology.

The energy storage solution used is based on the particularly safe and durable LiFePO4 battery technology, which enables long-term bridging of up to 100 hours. The intelligent DC emergency power supply with AC wide-range input thus reliably avoids system failures, downtime and data loss. The particularly robust design with IP65 protection makes the UPSI-2406IP-38AC the ideal choice for demanding environmental conditions. Four slotted holes on the housing enable secure and flexible wall or mast mounting (in combination with the mounting kit PSZ-1100). Typical applications include security, surveilance and building technology, energy, infrastructure, environmental engineering, communications, lighting, heavy industry, petrochemicals, agriculture, tunneling and mining.

Rugged aluminium housing with IP65 protection

The robust aluminium housing provides comprehensive protection for all components of the emergency power supply against mechanical impact. This includes the intelligent DC UPS control and charging electronics (24V/6A) with an upstream AC/DC converter as well as the built-in lithium iron phosphate battery pack. The housing elements and connections are carefully sealed and resistant to water, ice, oil and dust in accordance with protection class IP65.  A built-in pressure equalisation element with membrane prevents condensation from forming inside the unit. The operating temperature of the UPSI-2406IP-38AC covers a wide range from -20 to +50°C. The high-quality input and output cables are permanently installed on the housing.

Long-term bridging for 24VDC applications up to 100 hours

Uninterruptible power supply (UPS) of sensitive or safety-related 24VDC systems supplied from the AC mains is particularly important in case of blackouts, brownouts or flicker. For international use, the UPSI-2406IP-38AC has a wide-range AC input from 90 to 264 VAC with active PFC and high-efficiency AC/DC converter topology. In AC mains operation, which is automatically set after the input voltage is applied, the 24VDC output is activated and the integrated LiFePO4 energy storage is charged at the same time. In case of a voltage drop of the input voltage below the smallest nominal value, the UPS is switched to battery operation with regulated DC output voltage within fractions of a second and enables backup times of up to 100h. When the AC input voltage returns, the UPS is automatically switched back to regular mains operation and charging of the energy storage continues.

Integrated LiFePO4 high-performance battery pack

The LiFePO4 energy storage (lithium iron phosphate) with 330Wh convinces in safety-relevant applications with a particularly stable battery chemistry, a long service life of at least 10 years and more than 6000 full charge and discharge cycles. Bicker Elektronik deliberately uses the particularly safe lithium iron phosphate chemistry for all high-performance battery packs, which makes thermal runaway almost impossible. The UPSI-2406IP-38AC also meets the safety requirements of the IEC/EN 62040-1 standard. The battery management system (BMS) monitors and controls the complete charging and discharging process of each battery cell of the energy storage unit. The integrated cell balancing ensures a balanced and even charge of all cells so that the full capacity of the lithium iron phosphate battery pack remains permanently usable. In addition, the UPSI-2406IP-38AC offers a battery start function, which makes it possible to start a 24V application from the battery by pressing a button on the UPS (up to 6 A max. load current), without the AC voltage supply being present.
