ST, leveraging its technical capabilities to help carmakers achieve these goals, has announced an […]
Miniature dc-dc converters target industrial apps with 1-W output
Flex Power Modules introduces new families of miniature DC-DC converters for industrial applications: the PUA-A, PUC-B and PUB-M. The new devices are all isolating converters providing output power of up to 1W, with no minimum load required. Efficiency is typically 84% (PUA-A), 80% (PUC-B) and 81% (PUB-M) – all at full load. Input-to-output isolation voltage […]
High input voltage industrial dc-dc converters deliver 5-kW output
Absopulse has released the HVI 5K-3U7 series of high input voltage industrial DC-DC converters that deliver up to 5kW output power. A built-in redundancy diode allows for parallel connection of a number of 5kW converter units to create a 10kW, 15kW, or higher DC-power solution, and N+1 operation. The output separation diode also makes the […]
