Yokogawa launches WT1500 power analyzer with direct 2,000 V DC measurement for EV and energy storage testing
By Eve
Yokogawa Test & Measurement has released the WT1500, a four channel power analyzer that measures up to 2,000 V DC directly, removing the need for external high voltage dividers in test setups for electrified vehicles, energy storage and renewable power conversion. The 2U rack mount instrument offers total power accuracy of ±0.038% at DC and 50/60 Hz and supports two input element types: a High Voltage element for up to 2,000 V DC at 300 kHz and a Wide Bandwidth element for up to 1,000 V at 2 MHz. Yokogawa announced the product on 24 July 2026.
Why it matters: Direct high voltage measurement simplifies test bench configuration and reduces error for manufacturers validating EV charging hardware, power conversion systems and battery storage equipment. The dual element design in a single chassis allows testing teams to cover both DC charging infrastructure and high frequency motor drive applications without external dividers.
