NEW PULS 40A DC UPS CONTROLLER OFFERS MAXIMUM RELIABILITY AND FLEXIBILITY
reliable bridging of power failures and voltage fluctuations. This can prevent system damage, costly downtime, time-consuming restarts, and the loss of critical data. Applications include SMART
buildings and factories, Industry 4.0, security and CCTV, instrumentation and measuring systems. While the system power supply
provides sufficient voltage the DC-UPS controller will charge the battery bank. Should the supply voltage suddenly fail, the energy stored in the battery is released to the DC bus in a regulated process. A key feature of the UB series is
the PULS 1-Battery concept. To ensure the longest possible

ULS Power’s new UB40.241 40A rated DIN-Rail mounted controller for uninterruptible power
supply systems is now the most powerful UPS controller in PULS’s range, which already includes a variety of models currently providing up to 20A capacity. In combination with a 24Vdc power supply and an external battery pack it enables the
battery life, each 12V battery is charged and monitored separately. This smart function eliminates the need to match batteries. The UB40.241 allows precise charging, testing and optimised usage of the battery capacity. The control unit can be combined with different battery sizes from 12Ah to 200Ah with a selector
on the front of the device making it easy to adjust it to the corresponding battery size. Power output is decoupled from the input to provide separate circuits for buffered and non-buffered loads. The UB40.241 has various battery diagnostic
functions including an early pre-warning signal when the battery is low. This ensures safe and reliable operation of the entire system. Battery charging is temperature-controlled which also has a positive effect on the battery life. It also features a selectable buffer time limiter as well as signal contacts for system "Ready", "Buffering" and "Replace battery". For safety and maintenance reasons, an inhibit-input signal is included to enable phases without enforced buffering. The PULS UB40.241 has an operating
temperature range from -25°C to 70°C, 50% extra output power for up to 5s, has fully international safety agency approvals and a 3-year warranty. Marco van der Linden, UK Country Manager for
PULS Power, said: “Our new DC UPS controller doubles the amount of emergency power we can now offer systems designers and integrators ensuring maximum reliability and flexibility to protect critical loads while allowing the use of a comprehensive range of batteries with smart diagnosis and monitoring of battery condition.”

TINY 300W SINGLE OUTPUT POWER SUPPLY QUALIFIED FOR MEDICAL SYSTEMS
The VCCS300M measures just 4in x 2in x 1.61in with power densities
exceeding 23W/in³ and weighs just 310g. The VCCS300M delivers 300W of silent, fanless power and, where the application or environment demands, Vox Power has also designed these units to be cooled by convection or forced air. Importantly, power solutions of 300W, 600W, 900W and beyond can be
achieved by using the onboard droop current share function, which allows end users to scale up or down depending on their power requirements. Applications are widespread and include ventilators, respirators, endoscopes, lab equipment, dental systems and all types of mobile applications. Input voltage range is 85 to 264VAC (0.99 power factor) and output
voltages are set initially at 12, 24 and 48VDC with inbetween voltages up to 58VDC available on request. Figures for load and line regulation as well as ripple and noise are excellent while no load power consumption is below 1W.
Medical equipment designers will note that VCCS300M power supplies
A compact, conduction cooled, single output power supply designed specifically for medical systems applications is now availble from Vox Power. Widely known for its innovative approach to power supply design, Vox Power has combined the latest components and manufacturing techniques to exactly meet the needs of today’s demanding customer. With the new VCCS300M, the result is a very efficient (95%) and highly reliable (1.1 FPMH) power supply that will satisfy many applications right across the medical sector.

are BF rated, feature Class I & II isolation and meet all appropriate medical equipment standards including IEC/UL60601-1 Edition 3.1. and IEC/UL60601-1-2 Edition 4 (EMC). Apart from 95% efficiency, key features naturally include excellent low
leakage and touch current levels and protection against over voltage and over temperature, both with auto restart. Over current and short circuit protection are also standard. The new power supply is widely available from a global distribution
network and, in common with all its products, Vox Power backs the VCCS300M with a 5 year warranty.
