AC-AC Frequency converters deliver 2kVA stable sine wave voltage for heavy-duty industrial applications

2000VA Rugged, Industrial Quality AC-AC Frequency Converter with Sine Wave Output

AC-AC Frequency converters deliver 2kVA stable sine wave voltage for heavy-duty industrial applications. Photo shows the unit in a 3U5 chassis-mount enclosure.

The FC 2K-3U5 series of rugged AC-AC frequency converters deliver up to 2kVA pure sine wave output voltage from 115V, 230Vac or a universal 95-264Vac PFC input.  The units are suitable for applications that require clean, reliable AC-power in power utilities, industrial automation, mining, marine and transportation applications.

The AC-AC frequency converters are built with internal power modules. The AC-DC input stage boosts the input voltage to generate 115Vac at 60Hz/400Hz, or 230Vac at 50Hz. The output is regulated to ±6% from no load to full load; ±2% is available on request.  Typical conversion efficiency is 78% at full load. Custom input/output requirements can be accommodated on request.

The frequency converters use field proven, microprocessor controlled high frequency PWM technology to deliver the required output power. The high frequency conversion enables compact construction, low weight, and high efficiency.

The units have filtering on the input and output for low noise and are designed to meet EN 55032 Class A with margins; Class B on request. Comprehensive electronic protection minimizes the possibility of failure due to abnormal operating conditions, including application errors. Generous design headroom and the use of designed-in components with established reliability contribute to high MTBF.

Built-in fans draw air into the unit and provide sufficient cooling for operation over a 0°C to +50°C temperature range for full specification without derating. Wider temperature ranges are available on request.
