COSEL Launches New Compact 2”x3” Power Supply Series for Demanding Medical Applications

COSEL Co, Ltd today announced the expansion of its medical power offering with the addition of the new UMA series, the first two models being the 30W UMA30F and the 60W UMA60F. Both models feature a universal input range of 85 to 264VAC and comply with international safety standards. Designed for demanding medical applications, the UMA series is suitable for Body Floating (BF) applications and complies with 2MOPP (IN/OUT) and 1MOPP (OUT/FG) safety requirement. Based on a robust platform, the units’ design has been optimized to offer a very good price/performance ratio for medical applications requiring a high quality power solution. The UMA series is available in up to five output voltages of 5, 12, 15, 24, and 48VDC.

Medical applications are requiring robust and highly reliable power supplies that are able to operate around the world and comply with safety regulations. Based on many years of expertise, COSEL power designers developed an optimized flyback topology platform to offer an excellent price/performance ratio without compromising on quality and reliability. The UMA series can be operated within a universal Input range of 85 to 264VAC, and has a typical efficiency up to 91% at high line.

Currently four single output voltages are available as standard for the UMA30F: 5V/3A, 12V/2.5A, 24V/1.3A and 48V/0.65A, and five for the UMA60F: 5V/6A, 12V/4.5A, 15V/3.5A, 24V/2.5A and 48V/1.25A. Output is factory adjusted to a fixed value, but in applications where output voltage adjustment is required an option ‘Y’ with potentiometer is available.

The UMA series includes inrush current limiting circuitry, overcurrent, and overvoltage protection. Exhibiting versatility and robustness, the power supplies can be operated in an environmental temperature range of -20 to +70 degrees centigrade. Depending on the final equipment assembly style and cooling conditions, a derating may apply.

With its medical focus, the UMA series’ input to output isolation complies with 2MOPP, its input to Frame Ground (FG) complies with 1MOPP, and output to FG with 1MOPP. The units are approved in accordance with ANSI/AAMI ES60601-1 and EN60601-1 3rd Edition. In the case of Body Floating applications where patient leakage current must be less than 100 µA, with its 75 µA figure the UMA series is well below that limit and so eminently suitable for such applications.

The UMA series meets the following agency approvals: ANSI/AAMI ES60601-1, EN60601-1 3rd, C-UL (equivalent to CAN/CSA-C22.2 No.60601-1), UL62368-1, EN62368-1, C-UL (equivalent to CAN/CSA-C22.2 No.62368-1) and complies with EN60335-1.

To accommodate application specific requirements, three options are available including adjustable output voltage (Y), terminal block (T), and for applications requiring additional safety the UMA30F and UMA60F are available with reinforced isolation in conformance with the IEC class II (E).

The UMA30F measures 50.8 x 21.7 x 76.2mm [2.0 x 0.85 x 3.0 inches] (W x H x D) and weighs 80g max. The UMA60F is just 2.5mm taller (24.2mm) and weighs 120g max.

The UMA series has an excellent five-year warranty and conforms to the European RoHS and Low Voltage Directives.

The combination of small size, excellent cost/performance ratio, and high quality makes the UMA series an ideal power solution for demanding applications not only in the medical market but also for test and measurement, and industrial applications including household and similar electrical appliances.

Dr. Sachita Shah, Sr. Director, Global Health, Butterfly Network, "Butterfly is proud to continue improving maternal health equity through Phase Two of the largest-scale handheld ultrasound distribution and training ever conducted in Sub-Saharan Africa. South Africa is an emerging market that continues to have disproportionately high rates of maternal mortality and stillbirth. Patients need easier access to antenatal imaging, and clinicians need better capabilities for screening high-risk conditions that lead to disproportionately worse pregnancy outcomes in rural areas in the public sector. Together with CHAI and GUSI, we can tackle this by making ultrasound much more accessible, so high-risk conditions can be identified earlier in care, which is known to improve outcomes.”
The clinical Study will enroll up to 97 patients at up to 12 European investigational sites. Completion of the study is expected this year, and results will support CE mark and pre-market approval submissions reports Vivasure Medical.
Dr. Michael Newman, Indaptus’ Founder, Chief Scientific Officer, and lead author, commented, “The new data are consistent with our preclinical animal tumor model studies and provide evidence for our hypothesis that patented Decoy bacteria can activate a wide range of innate and adaptive human immune cells involved in fighting tumors.  This aligns with what we’ve observed in our ongoing Phase 1 clinical trial of Decoy20 – broad immune activation, as evidenced by transiently increased levels of many key cytokines and chemokines following single dose administration. These findings bolster our confidence in Decoy20's potential as a multifaceted immunotherapy.”
