Extremely rugged DC UPS with maintenance-free longlife Supercaps, IP67 protection and ultra-wide input range

Extensive application possibilities
Typical applications of UPSI-IP-2 series include i.a. heavy industry, petrochemical industry, tunneling and mining, safety and building technology, offshore / onshore energy, communications, commercial and special vehicles, industrial trucks, food, pharmaceutical and chemical industries, agriculture, medical and laboratory technology. The UPS systems ensure the uninterruptible and safe DC power supply of sensitive and process-relevant control modules, embedded computers, actuators, sensors, motor drives, etc.

Maintenance-free Supercap energy storage technology
Unlike batteries, which store energy by the detour of a chemical reaction, ultracapacitors (Supercaps) are based on the electrophysical principles of the double-layer capacitor and are charged and ready for use within a very short time, operate in a wide operating temperature range and convince with a high current-carrying capacity, power density and reliability. Due to the high cycle stability (> 500,000 charge and discharge cycles), energy storage units with Supercaps have a particularly long service life and are practically maintenance-free. For the supplied application, this means an increase in long-term availability while minimizing maintenance efforts.

Ultra-wide-range input with integrated EMC filter
On the input side, both DC UPS systems have a high-efficiency DC-DC converter with ultra-wide-range input from 7 to 36 VDC (UPSI-1208IP-23UW) or 8 to 36 VDC (UPSI-2406IP-24UW). To suppress network-sided electromagnetic interference, an additional EMC filter module is upstream of the converter.

Intelligent DC UPS control and charging electronics
In normal operation, the μC-controlled system electronics of the integrated UPS module provide the nominal output voltage, charge the supercapacitors and monitor the voltage thresholds at the input. If the voltage falls below the defined voltage threshold, the system switches to the UPS backup mode within fractions of a second and ensures the uninterruptible and regulated output voltage for 12VDC or 24VDC consumers. The intelligent distribution of charging currents (PowerSharing) ensures that the input power is kept constant and distributed accordingly to the supplied load and the Supercap charger. With a lower load at the output, more energy flows into the Supercap charger and vice versa.

Minimum load detection (load sensor)
The minimum load detection monitors the supplied output load during UPS backup operation. If the load at the output falls below a certain limit, the longlife Supercaps are automatically disconnected from the control unit so that the energy storage device is not unnecessarily emptied by the DC UPS electronics.

Reboot function for self-sufficient systems
The integrated reboot function can be used to activate the automatic restart of a supplied computer system as soon as the mains voltage returns during a shutdown or at a later time. For example, self-sufficient IPC or embedded box PC systems can be shut down in a controlled manner after a power failure and then restarted independently without any intervention of a service employee being necessary.

Software connection, pre-programming and monitoring
To set and pre-program the UPS parameters as well as for energy storage monitoring, the UPS software "UPSI HID Configuration" is available for free download at the respective product at www.bicker.de. For data communication with controllers or PC-based systems, the UPSI-IP-2 series has an integrated USB communication interface. In addition, a comprehensive instruction set enables the direct readout of sensor values and setting of parameters. The open communication protocol offers system developers individual possibilities of connection to their own system.

Robust aluminum housing with IP67 protection
A robust aluminum housing with pressure compensation element protects electronics and energy storage against mechanical effects. The sealed housing elements and connections are resistant to water, ice, oil and dust according to protection class IP67. Mounting brackets are already mounted on the housing for quick and secure installation.

Long-term availability and comprehensive value-added services
The company Bicker Elektronik grants a three-year warranty on the UPSI-IP-2 series, as well as a long-term availability of at least 5 years. For applications with long running time an optimal investment protection is given. System developers also benefit from personal design-in advice and first-class service and support from Bicker Elektronik’s power supply specialists. On request, the R&D engineers realize customer-specific special solutions and also offer extensive laboratory and measurement services for complete customer systems.

UPSI-IP-2 series also available with LiFePO4 battery technology
For even longer bridging times, Bicker Elektronik also offers the UPSI-IP-2 system with lithium-ion battery technology based on particularly safe and long-lasting lithium iron phosphate cells. Compared to LCO / NMC cells, the LiFePO4 cells have a much more stable chemical compound of the cathode material and convince with increased safety and a roughly ten times higher cycle stability (6,000 charging and discharging cycles). Bicker’s high-quality BP-LFP battery packs also feature an integrated high-performance battery management system (BMS) to maximize service life.
