ABSOPULSE Electronics’ HTH 1K-F6W is a 3-phase high voltage AC-DC power supply designed for 1000W industrial applications.  The 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. 

The HTH 1K-F6W 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.

The power supply is verified for 5600Vdc input to output isolation and production level testing is 4300Vdc input to output; this isolates equipment from the supply and contributes to high reliability and long operating life of the unit.
