PXe-S Series Single Phase Static Frequency Converter

Q: What is a single phase static frequency converter (SFC) used for?

A single phase static frequency converter is used to convert electrical power from one voltage and frequency to another, typically from 230V 50Hz to 115V 60Hz, 60Hz to 50Hz and to 400Hz. This allows testing of ac powered electronic modules, small motors and other single phase equipment where appropriate supply voltage and frequency must be connected

Q: Can a single phase static frequency converter SFC convert 50Hz to 60Hz?

Yes, the PX Electronics single phase static frequency converters converts 50Hz to 60Hz and can be configured for 60Hz to 50Hz or 50/60Hz to 400Hz

Q: Can a single phase static frequency converter (SFC) convert to three phase?

Yes a single phase static frequency converter (SFC) can convert to three phase 50Hz, 60Hz and 400Hz along with various voltage options Model PXe-130000-S

Q: Can the system convert from USA 60Hz to European or Asian 50Hz?

Yes. The SFC system can be convert 60Hz to 50Hz. This is useful when operating European or UK equipment in US, Cananda and South America 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 and is much lighter and more compact than rotating machinery. The SFC provides greater control over output voltage and frequency, along with precise control of Voltage and current protection. Unlike rotary machines there is no mechanical maintenance requirements

Q: Is this suitable for laboratory and bench testing?

Yes. Compact single phase SFC models are well suited to laboratories and bench testing, product validation areas and technical workshops where controlled AC voltage and frequency output is required

Q: Can this be used for imported or export equipment testing?

Yes, the PXe SFC can this be used for imported or export equipment testing. Manufacturers can use a 50Hz to 60Hz or 60Hz to 50Hz static frequency converter to test equipment under the same operating electrical conditions as the destination country. This is useful for validation, factory acceptance testing and production quality checks

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

Key information includes the available input supply voltage and frequency, output voltage and frequency, load power rating kVA, load type, knowledge of starting or inrush current, indoor/outdoor operating environment and any control or communication requirements like EtherNet RS485

Q: How do Static Frequency Converter SFC fault diagnostic systems work?

Static Frequency Converter SFC fault diagnostic systems work by monitoring temperature, voltage, current, power and phase loss. These errors are written to Non-Volatile RAM (NVRAM) for later viewing. SIL Safety Integrity Level "Watch-Dog" options are available for independent monitoring and reporting

Q: What is a SFC Watch-Dog System used for?

Watch-dog or independent fault-monitoring systems are available for monitoring and reporting the health of Static Frequency Converters, particularly high kVA units. These autonomous fault diagnostic systems work by monitoring temperature, voltage, current, power, and phase loss. The Watch Dog provides monitoring even with catastrophic power loss, errors can be written to Non-Volatile RAM, Networks and sent via SMS or VPN

PX Electronics PXe-110000-S Series single phase static frequency converters provide compact AC frequency conversion for laboratories, test benches, avionics workshops, marine equipment and specialist single phase loads. Designed for weight and compactness for 50Hz to 60Hz, 60Hz to 50Hz and selected 400Hz output requirements, the range allows engineers to operate or validate equipment under the correct supply frequency without relying on utility power and mains conditions.

Compact models are available for smaller technical installations, while higher-rated systems can be configured for continuous-duty operation, voltage matching and remote monitoring. Typical uses include product testing, operation of imported equipment, export validation, aerospace equipment checks, and controlled laboratory power applications.

Technical Highlights for Single Phase Frequency Conversion:

50Hz, 60Hz and 400Hz output options
Supports common single phase frequency conversion requirements, including 50Hz to 60Hz, 60Hz to 50Hz and optional 400Hz configurations for specialist applications.

Solid-state double conversion design
AC to DC to AC conversion using IGBT PWM technology provides a lightweight yet stable output frequency and controlled AC power for test and operational use.

Harmonic Mitigation Strategy
Optional 12-pulse and 18-pulse rectifier technology reduces input current harmonic distortion by cancelling dominant lower-order harmonics, improving supply compatibility and overall power quality.

Clean sine-wave output
Designed to provide low-distortion AC output suitable for sensitive equipment, laboratory instruments and frequency-dependent electrical loads.

Integrated isolation transformer
Output transformer isolation helps provide electrical separation between input and output, while reducing noise and supporting safer equipment integration.

PXe-110000-S Series Configuration:

PXe-110000-S Series single-phase static frequency converters can be configured based on the available site supply, required output voltage, output frequency, load rating, and installation format. Standard conversion duties include 50Hz and 60Hz operation, with 400Hz and other specialist frequency outputs available where required.

The range is suitable for compact bench and laboratory use, but can also be specified for higher-power single-phase applications where continuous operation, voltage matching or equipment compatibility is required. The output voltage and frequency can be fixed or adjustable, depending on the test requirements and the connected load.

Each converter uses solid-state IGBT PWM conversion with transformer isolation and sine-wave AC output. Front-panel metering provides quick visibility into voltage, current, and frequency, while optional interfaces such as RS-232, RS-485, Ethernet, or GPIB can be included for remote control or automated testing.

Enclosure options can be selected to suit the installation, including compact bench units, rack-mounted systems, floor-standing cabinets or mobile arrangements for workshop and service use.

PXe-110000-S Series Order Codes:

A product order code can be derived from the main ordering information using the structure below:

Generic order code is based on this format: PXe-110000-S, and all PXE order codes start with the six digits like 110005 in this case, indicating 1ph-input 1ph-output and 5kVA

For example a 1 phase in 50Hz, 1 phase out, 10kVA, 60Hz unit = PXE-110010-S
