PXe Series – Static Frequency Converter | AC Power Supplies

The PXe Series Static Frequency Converter is a high-performance AC power supply that enables seamless frequency conversion—whether 50Hz ↔ 60Hz, or even up to 400Hz, with user-definable frequencies like 6.67Hz, 25Hz, and 100Hz. Available in both single-phase (0.5kVA–200kVA) and three-phase (1kVA–2000kVA) models, it features a rectifier-inverter architecture using PWM and IGBT technology, and includes an isolation transformer to eliminate ground loops.

PXe Series Static Frequency Converter Key Highlights:

Clean, utility-quality output: Pure sine-wave with low total harmonic distortion (≤ 3% THD).
User-friendly interface: LED display and tactile buttons for easy control.
Robust protections: Safeguards against over-temperature, over-voltage, excessive current, short circuit, and more.
Flexible configurations: Choose between fixed and adjustable output voltages and frequencies, single- or three-phase setups, and optional interface modules (RS-232C/RS-485/GPIB).

Ideal for:

R&D, product compliance testing, performance validation, and ensuring equipment functions correctly under various frequency conditions.
Aerospace & avionics testing (particularly 400Hz systems), marine and shoreside power applications, industrial machinery, and laboratory equipment.

Available in various model sizes from compact 1kVA single-phase units to large-scale 2000kVA three-phase systems. This converter is your versatile solution for reliable, safe, and precise AC power conditioning across diverse applications
