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.
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.
