Yokogawa Test & Measurement has introduced the WT1500 Precision Power Analyzer, a new high-accuracy instrument designed specifically for testing electric vehicle (xEV) powertrains, batteries, energy storage systems (ESS), and power conversion systems (PCS). The analyzer features direct 2000 V DC input capability for the first time in the WT series, eliminating the need for external high-voltage dividers.

Key Specifications & Features

• Total power accuracy: ±0.038% (DC and 50/60 Hz)
• Low power factor accuracy: ±0.07% of apparent power at 50/60 Hz
• Direct DC voltage measurement: up to 2000 V with 300 kHz bandwidth
• High-voltage capability: up to 1000 V with 2 MHz bandwidth
• Resolver signal support combined with power measurement in one instrument
• IEEE 1588 time synchronization
• Data output: CAN, CAN FD, and UDP
• Form factor: Compact 2U rack-mount design
• Channel expansion: Up to 5 units can be synchronized for a total of 20 power measurement channels
• Current inputs: 4 terminals that power connected sensors
• Supports CT Series sensors (60 A – 2000 A AC/DC), CT1000S split-core (1000 A), and clamp probes (50 A / 200 A)

The WT1500 supports four-channel measurements for both single-phase and three-phase systems. It allows remote operation from a PC, monitor, or tablet and includes a compact front-panel interface for quick setup.

Target Applications

• EV powertrains and e-Axle systems
• Inverters and power conversion systems (PCS)
• Battery and energy storage systems (ESS)
• High-voltage DC testing in automotive and renewable energy

By combining high voltage capability, excellent accuracy, and multi-channel synchronization in a compact package, the WT1500 simplifies complex EV and battery testing setups while improving measurement reliability.
