335V Load Box

Powermetrix 335V

The Powermetrix 335V Load Box is a battery-powered voltage and current source designed for use with the Powermetrix 6618A analyzer, enabling phantom load meter testing up to 277 VAC and 5A while supporting the current harmonic waveforms referenced in ANSI C12.1.

It expands field capability with CT added burden, direct burden measurement, and CT demagnetization, all in a compact, single-case package that stores the analyzer and standard test accessories.

Product Highlights

Take full testing capability anywhere—without hunting for auxiliary power. With an internal 100 Whr Li‑Ion battery designed to support a full day of testing, the Powermetrix 335V makes portable meter work more practical for substation testing, site verification, and revenue protection applications.

Get deeper insight and more confidence in results. The Powermetrix 6618A/335V kit supports advanced testing workflows including vector display, harmonic analysis, energy testing (Wh, VAh, VARh, I²h), element testing, and calibration verification, while adding targeted CT-focused functions like CT added burden + ratio testing and direct burden measurement for more complete troubleshooting.
