Hp50 series products provide customers with wide voltage input (85-305vac, 70-400vdc), EMC up to level 4 (en61000-6-2, class a heavy industry standard), low ripple, low noise, output overload, short circuit protection, high efficiency, high power density, minimum in the industry, low power consumption, green environmental protection, no-load loss < 0.1W, 3-year quality assurance, 100% high-temperature aging and high stability in testing Ultra small volume modular switching power supply. At the same time, this series of modular power supply also has the characteristics of small volume, high reliability, high isolation voltage, high cost performance and so on. This series of products are mainly used in instruments and other related equipment in heavy industrial environment. If they are used in worse electromagnetic compatibility environment, they must refer to the application circuit.
