PXe Three Phase Static Frequency Converters

Q: What is a three phase static frequency converter used for?

A three phase static frequency converter is used to convert electrical power from one frequency to another, typically between 50Hz and 60Hz. This allows industrial machinery, motors, pumps, compressors and other three phase equipment to operate from a supply frequency different to the one it was originally designed for.

Q: Can a three phase frequency converter convert 50Hz to 60Hz?

Yes. PX Electronics three phase static frequency converters can be configured for 50Hz to 60Hz conversion, allowing equipment designed for 60Hz operation to run from a 50Hz mains supply.

Q: Can the system convert 60Hz to 50Hz?

Yes. The system can also be configured for 60Hz to 50Hz conversion. This is useful when operating European or UK equipment in regions where the available mains supply is 60Hz.

Q: Why use a static frequency converter instead of a rotary converter?

A static frequency converter uses solid-state power electronics rather than rotating machinery. This typically reduces mechanical maintenance requirements and allows more precise control of output voltage and frequency.

Q: Is this suitable for industrial machinery?

Yes. Three phase static frequency converters are commonly used with industrial machinery, production equipment, motors, pumps, compressors, HVAC systems and specialist electrical loads. The final system rating should be selected based on the load type, starting current, and operating duty.

Q: Can it be used for export equipment testing?

Yes. Manufacturers can use a 50Hz to 60Hz or 60Hz to 50Hz frequency converter to test equipment under the same electrical conditions it will experience in the destination country. This is useful for export validation, factory acceptance testing and production quality checks.

Q: Is this suitable for marine shore power applications?

Yes, where the voltage, frequency and power rating are correctly specified. Three phase frequency converters are often used in marine and shore power applications where vessel or dockside equipment requires a different supply frequency.

Q: What information is needed to specify a three phase static frequency converter?

Key information includes the available input supply, required output voltage and frequency, load power rating, load type, starting current, duty cycle, installation environment and any control or communication requirements.

Q: Can PX Electronics supply custom configurations?

Yes. PX Electronics can provide configurations to suit different voltage, frequency, power rating, enclosure, control and monitoring requirements. This is particularly useful for industrial, marine, and export testing applications where standard supply conditions do not match those of the connected equipment.

PX Electronics three phase static frequency converters provide reliable 50Hz to 60Hz and 60Hz to 50Hz power conversion for industrial equipment, marine systems, export testing and manufacturing environments. Designed for continuous-duty operation, they deliver stable three-phase output for machinery, motors, pumps, compressors and specialist electrical loads.

Using solid-state IGBT PWM conversion technology, each system converts incoming AC power to DC, then generates a controlled AC output at the required frequency. This makes the range suitable for equipment operating across different global power standards, including imported machinery, export production testing and industrial sites requiring dependable frequency conversion.

Configuration:

PXe three phase static frequency converters can be configured to suit a wide range of input supplies, output frequencies, installation formats and control requirements. Systems are available for standard 50Hz and 60Hz conversion duties, with 400Hz output options for aircraft or specialist equipment power requirements.

The range covers output ratings from 1kVA to 500kVA, allowing systems to be specified for small test loads, production equipment, larger machinery, and higher-power operational loads. Input and output voltages can be matched to the site supply and connected equipment, helping customers operate machinery or test products under the correct electrical conditions.

Each converter is built around solid-state IGBT PWM conversion with sine-wave AC output and integrated transformer isolation. This supports electrical separation between input and output, while helping reduce noise and improve compatibility with connected equipment.

Operators can monitor key values from the front panel, including voltage, current, frequency and system status. Protection functions are built into the system to respond to abnormal operating conditions such as overload, short circuit, over-temperature and phase loss.

Depending on the project, units can be supplied as rack-mounted, floor-standing or mobile enclosure systems. Remote monitoring and communication interfaces, including RS-232, RS-485 and Ethernet, are available where integration with wider control or test systems is required.
