3-phase high voltage AC-DC power supply designed for 1kW industrial applications


3-phase AC-DC power supply offers 400Vac input, 200Vdc output  

3-phase, 400Vac Input, 200Vdc Output, 1000W Industrial Quality AC-DC Power Supply

3-phase high voltage AC-DC power supply designed to meet the needs of  heavy-duty 1kW industrial applications

The HTH 1K-F6W 3-phase high voltage AC-DC power supply is 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 1kW, 3-phase AC-DC power supply is used to power industrial applications including as DC motor control, battery charging, DC bus voltage for distributed systems and power servos.

Cooling by conduction via a heat-sinking surface (chassis or cabinet wall), and the use of high quality internal fans provide sufficient cooling for operation over a 0°C to +50°C temperature range for full specification without derating. If you require wider temperature ranges, please let us know.

The HTH 1K-F6W three-phase 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. Further electronic protection includes inrush current limiting, output current limiting with short-circuit protection and thermal shutdown in case of insufficient cooling and output over-voltage protection. The units are designed for compliance with EN/UL60950-1 and equivalent safety standards. Filtering on the input and output contributes to low output ripple and noise. The input meets EN55022 Class A with wide margins with Class B available as an option.

The power supply is ruggedized for resistance to shock and vibration and meets IEC 61373 Cat 1 A&B. Conformal coating ensures protection from humidity and airborne contaminants. Built on a single PCB, the power supply is low profile (65 mm),  light weight and delivers a 1kW cost-effective solution.  

We also offer an extensive line of three-phase input power supplies including the HTP 300-FX, HTP 500-FXW Series HVI 3KP-V9 Series, and HVI 3K5-3U4 Series.
