December 04, 2017 DPW’s Subsidiary Coolisys Technologies Unveils Its First Cryptocurrency Hardware

Targets Popular Antminer Model S9 to Launch Power Product Line for Digital Miners

Coolisys stated that the first miner AC-DC switching power supply being produced will be for use by the Antminer S9 model by Bitmain Masters and can now be pre-ordered. The very popular and highly regarded Antminer S9 was the world’s first dedicated bitcoin miner using an application-specific integrated circuit, (commonly known as an ’ASIC’), based on the sixteen nanometer (“16nm”) process on its system. Coolisys noted the new product line was a result of the agreement with PoW Digital Mining previously announced on August 10, 2017, which said ‘PoW Digital Mining is to lead its development of an equipment and services portfolio targeting Digital Mining and related research and development of cryptocurrency. The active digital mining markets led by Bitcoin, Ethereum and the other 900+ digital currencies have created a budding hardware demand driving the need for efficient low-cost power solutions.’ PoW Digital Mining affirmed that the top issue for most professionals and amateurs who actively mine Bitcoin, Litecoin and other cryptocurrencies is energy costs. Cryptocurrency mining of block-chain transactions is power-hungry. The most successful miners are those that get the highest hash rates out of their systems, at the lowest total cost. Since electricity is the biggest on-going cost of mining, it follows that maximizing the efficiency of the power supply is critical. Even with the smallest of efficiencies delivering notable savings, PoW Digital Mining reported that a new line of crypto-mining power solutions within a suite of products could be readily commercialized.

Amos Kohn, President and CEO of Coolisys Technologies and Digital Power Corporation stated, “We have a competitive advantage given our expertise in developing and providing advance power solutions for the tech, military, industrial and healthcare sectors. To power the AntMiner S9, we will utilize our field-proven platform, previously implemented to power cloud-based computing networks and servers, that employ highly-efficient power switching with fully synchronous rectification and advanced digital signal processing (DSP). Our power solutions are based on next-generation design and we believe are among the most technologically advanced power processing solutions available. We project our cryptocurrency initiatives and products could have a material effect on the Company’s revenues and net income for this component of its operations during 2018. We look forward to presenting what we are developing.”
