Engineering Excellence

Authorized Behlman Representative & Global AC Power Specialist

Powerstax serves as the authorized international engineering representative for Behlman Electronics Inc., bringing over 65 years of pioneering power technology to overseas procurement managers, defense contractors, and industrial system integrators.

Our comprehensive line of AC power supplies and frequency converters delivers cost-effective, low-distortion AC conversion. Designed to solve complex international voltage and frequency adaptation challenges, these systems convert single-phase or three-phase utility grid inputs into clean, programmable AC power ranging from 45 Hz up to 10 kHz, including fixed 400 Hz airborne and marine power standards.

Key Application Sectors

  • Avionics & Aerospace: 115 VAC @ 400 Hz ground power, airborne power supplies, and flight simulator power sources.
  • Production & ATE Testing: Automated test equipment (ATE) needing variable voltage (0–300 VAC) and multi-frequency sweep capabilities.
  • Defense & Naval Systems: Ruggedized, MIL-STD-810, MIL-STD-461, and MIL-STD-1399 compliant 3-phase frequency converters for harsh environments.
  • Oil, Gas & Utilities: Reliable frequency conversion for remote exploration rigs, subsea control gear, and global plant exports.
