PXe Commercial Static Frequency Converters SFC

A robust, solid-state solution for AC frequency conversion. PX Electronics Commercial Static Frequency Converters are ideal for testing, industrial, aerospace, and marine applications.

Highlights:

Flexible frequency conversion: Supports standard conversions (50 Hz ↔ 60 Hz, 50/60 Hz → 400 Hz) and custom output frequencies (e.g., 6.67 Hz, 25 Hz, 100 Hz)
Scalable capacity: Available in single- and three-phase models ranging from 0.5 kVA to 200 kVA (and up to 2000 kVA in extended PXe series)
Clean, reliable output: Uses PWM and IGBT-based inversion with built-in rectifier and isolation transformer to deliver low THD, pure sine wave output with galvanic isolation
User-friendly and protected: Features LED/LCD controls plus comprehensive protections (over-temperature, over/under-voltage, over-current, etc.)
Versatile applications:
- Product and compliance testing (e.g., voltage, frequency, drop-out conditions)
- Aviation & avionics (simulating 400 Hz power systems)
- Marine & shore power integration
- Lab and industrial equipment testing
- Variable-speed motor/fan/pump control setups
