a design concept emphasising longevity, high-end technical specifications and low cost of ownership. Its power supplies are fast, reacting more than 10 times


faster to load transients than comparable alternatives available today, with minimum audible noise and 10-30 times less electromagnetic interference (EMI), for reliable, quiet operation and protection against immunity. All Delta Elektronika’s DC power supply units are


thoroughly tested before being dispatched to customers. In addition to high-performance DC power supplies,


Delta Elektronika provides outstanding service and technical support to customers - even for equipment that was bought many years ago. Product support continues 10 years after production has ceased.

Maintenance-free DC UPS modules for DIN rail mounting protect against power failure, brownout and flicker


SuperCaps as maintenance-free energy storage


Unlike batteries, which store energy by the detour of a chemical reaction, SuperCaps are based on electrophysical principles and are charged and ready for use within a very short time, operate in a wide temperature range and convince with high current-carrying capacity, power density and reliability. Due to the high cycle stability of more than 500,000 charge and discharge cycles, DC UPS systems with SuperCaps are practically maintenance-free and have a particularly long service life. For the supplied system, this means an increase in long-term availability while at the same time minimising maintenance. The high-quality SuperCaps are fully charged in a maximum of 60 seconds and designed for fanless 24/7 continuous operation in the extended temperature range of -20 to +70 °C.


Intelligent charging and control electronics


In normal operation, the µC-controlled system electronics of DC UPS modules UPSIC- 1205D / UPSIC-2403D pass the input voltage, reduced by a voltage drop of 0.3 V / 0.2 V (@ full load), to the output. At the same time the SuperCaps are charged and the voltage thresholds at the input are monitored. If the input voltage falls below the defined voltage threshold, the system switches to the UPS backup mode within fractions of a second and ensures an uninterruptible and regulated power supply at the output. The intelligent distribution of the charging currents (PowerSharing) ensures that the upstream AC/DC power supply does not have to be oversized, but the input power is kept constant and distributed accordingly to the supplied load and the SuperCap charger. With less load at the output, more energy flows into SuperCap charger and vice versa.


Front-side interfaces T


wo new DC UPS compact modules from Bicker Elektronik ensure the uninterruptible power supply of DC loads such as low-power embedded IPCs, gateways, motors,


sensors, actuators or cameras in the field of industrial control, process and automation technology, medical and laboratory applications as well as safety equipment. For protection against voltage fluctuation, brownout, flicker or power failure, the modules UPSIC-1205D (12 VDC / 5A) or UPSIC-2403D (24 VDC / 3A) are equipped with ultracapacitors (so-called SuperCaps) as maintenance-free energy storage and have an intelligent charging and control electronics. All components are housed in a robust aluminium chassis with a DIN rail bracket for fast DIN rail mounting in control cabinets.


CONNECTINGINDUSTRY.COM/ELECTRONICS


All inputs and outputs are located on the front of the compact DC UPS module. In addition to the connections for input and output voltage with control LEDs, these include a relay contact (PowerFail), an RS232 communication interface (DSUB) and shutdown signal outputs. The DC UPS modules are also equipped with an active reverse polarity protection and protected against overload (shutdown with automatic restart).
