WT300E

The WT300E series digital power analyzer targets extremely low-current and standby-power measurements. It resolves currents down to 50 µA while supporting up to 26 A RMS, making it well suited to Energy Star, SPECpower, IEC 62301 / EN 50564, battery-charger, and other low-level power tests.

Engineers use WT300E when conventional power meters lack sensitivity for standby and harmonic-related compliance work. Multiple input elements and harmonic analysis options (model dependent) cover single- and multi-phase configurations. Clear numeric displays and PC connectivity simplify logging for certification labs and production sampling.

Pair the instrument with appropriate voltage/current sensors and follow the relevant energy-efficiency standard’s setup guidance for repeatable results.

• Low-current measurement from 50 µA; max ~26 A RMS
• Ideal for standby power / Energy Star / IEC62301 / EN50564 testing
• Battery charger and low-level power characterization
• Digital power analyzer with PC connectivity for logging and reports
