PXe Three Phase Static Frequency Converters SFC

PX Electronics Three Phase Static Frequency Converters are a powerful, solid-state system ideal for converting AC power frequencies with precision and reliability.

Key Highlights:

Flexible frequency conversion — Supports standard conversions (e.g., 50 Hz ⇄ 60 Hz, 50/60 Hz → 400 Hz) and user-specified frequencies like 6.67 Hz, 25 Hz, or 100 Hz
Wide capacity range — Available in three-phase models from 1 kVA up to 200 kVA
Advanced conversion technology — Uses robust rectification (6- or 12-pulse), IGBT-based PWM inversion, and an isolation transformer. Providing clean, stable output power and eliminating ground loops
Pure, low-distortion output — Delivers a true sine wave with low total harmonic distortion (THD)
Intuitive control and protection — Equipped with LED/LCD display and tactile buttons. Plus safeguards against over-temperature, over-/under-voltage, over-current, and more
Ideal for demanding environments — Widely used for testing imported/exported products, aviation and avionics systems (including 400 Hz circuits), marine systems, laboratories, industrial equipment, and motor/fan/pump setups
