Static Frequency Converters for Maritime, Avionics, Industrial and Defence Applications

What is a Static Frequency Converter?

The name suggests a Static Frequency Converter or SFC, changes from one power frequency to another, usually at a fixed installation. In addition, most SFCs will allow a change from one voltage to another. Applications include maritime docks, avionics testing, airport ground power and appliance testing.

The Powertek static frequency converters serve as a popular frequency changer: AC Power 50Hz to 60Hz, 60Hz to 50Hz or 50/60Hz utility power to 400Hz. Specialist frequency conversions are possible 16.67Hz/25Hz/100Hz. Our Ptk-33000, Ptk-FCM and Ptk-SFC series static converters utilize a built-in rectifier, converting incoming AC power into DC, then inverting the DC to the required frequency and voltage based on IGBT switching and a built-in isolation transformer. The Ptk-FCM series has many advantages, making them ideal for export product testing or operational test of imported equipment helped with their command and control interfaces. Applications such as the testing of military/avionics equipment, typically 400Hz electronics operated in aircraft, where maximum and minimum conditions are simulated. For aircraft ground power, fixed wing and helicopter applications, GPU or a military vessels, a variety of formats are possible including dual o/p combinations 28Vdc/120Vac 3ph 400Hz GPUs

Approvals and conformance: DFS400: Specification for 400 Hz aircraft power, ISO 6858:Aircraft ground support electric supplies, MIL-STD-704F: Aircraft electric power characteristics, MH/T6018 Aircraft ground solid state power unit, EN61000-6-4 Electromagnectic compatibility generic emission, EN61000-6-2 Electromagnectic compatibility generic immunity

PXe-AFV-P Programmable Rack-Mount AC Source

View our range of PXe-AFV-P static frequency converters. This is a programmable AC power source with DC output capability and precision AC measurement. Available in four power levels 600VA, 1250VA, 2500VA and 5000VA, providing clean sine outputs with distortion less than 0.3% at 50/60Hz. The series provides 0–310 VAC output and a frequency range of 40–1000 Hz, making it suitable for commercial, defence and aerospace applications. Test sequences can be stored, while transient generation functions simulate voltage surges, drops and frequency disturbances. With peak current capability of up to 4.5 times the maximum rated current, it is ideal for inrush current testing. Measurement functions include RMS voltage and current, true and apparent power, power factor, crest factor and reactive power. The AC source can be remotely controlled via USB, RS232/RS485, LAN, optional GPIB or analogue control. Control software, Modbus and LabVIEW drivers are also available for easy programming and remote operation.
