PXe Commercial Static Frequency Converters SFC

The PXe Commercial Static Frequency Converters are a versatile device used to convert AC power frequency to another. SFC are capable of converting frequencies such as 50Hz to 60Hz, 60Hz to 50Hz, 50Hz to 400Hz and 60Hz to 400Hz. These converters also allow user-defined frequency conversions, such as 6.67Hz, 25Hz, and 100Hz.

The range of SFC models available includes single-phase and three-phase units ranging from 0.5kVA to 200kVA capacity. The specification tab provides further details on available options within the range.

We can provide transformers to complement our SFC range, as well as IP54 rated cases, bespoke intelligent power solutions for test setups and much more.

Our Static Frequency Converters involve a built-in rectifier that converts the incoming AC power into DC. This DC power is then inverted into the desired frequency and voltage using PWM (Pulse Width Modulation) and IGBT (Insulated Gate Bipolar Transistor) switching. The conversion process also includes EMI, built-in isolation transformer, which is crucial for achieving input-output isolation and eliminating ground loops. Closed loop control systems ensure fast response and stability.

The PXe compact and flexible converters offer several advantages, making them well-suited for various applications. They are commonly used for product testing of imported/exported frequency dependent equipment. Additionally, our SFCs find extensive use in testing commercial and military aerospace avionics equipment, including the operation of electronics that rely on 400Hz power onboard aircraft or military vessels. These converters facilitate the testing of maximum and minimum AC parameters such as drop-out voltage, current, and frequency range.

Key Features of the PXe Commercial Static Frequency Converter include:

Double conversion: AC to DC rectification followed by DC to AC inversion
PWM and IGBT technology: Ensures efficient and accurate frequency conversion
Low harmonic distortion and Total Harmonic Distortion (THD): Produces clean power output with minimal harmonic content
Pure sine wave output: Replicates the quality of utility power
LED or LCD displays along with tactile keyboard provides user-friendly interface for monitoring and control
Comprehensive protection: Includes features to safeguard against over-temperature, over-voltage, under-voltage, over current, and power issues
Fixed and variable frequency selection: Allows testing flexibility in choosing the desired output frequency
Single-phase and three-phase availability: Cater to different power requirements
Galvanic transformer isolation: Ensures input-output isolation, crucial for eliminating ground loops and maintaining system integrity and risk

Overall, the PXe Static Frequency Converters offer reliable and efficient frequency conversion solutions for a wide range of applications, ensuring correct operation of equipment under varying frequency and voltage conditions.
