January 20, 2020  Stephen Law

ABSOPULSE ELECTRONICS HTH 1K-F6W rugged 3-phase high voltage ac-dc power supply is suitable for 1000W industrial applications. Unit operates from a three-phase line input of 400Vac (340-446Vac range) and delivers a 200Vdc single output. Similar power supplies that operate from 380Vac or 480Vac 3-phase sources are also available on request. Unit is typically used to power industrial applications such as dc motor control, battery charging, dc bus voltage for distributed systems and power servos. Cooling by conduction via a heat-sinking surface and high quality internal fans provide sufficient cooling for operation over a 0°C to +50°C temperature range for full specification without derating. Product is verified for 5600Vdc input to output isolation. Production level testing of 4300Vdc input to output isolates equipment from the supply and contributes to high reliability and long operating life of the unit.
