**- Basic accuracy ±0.03%, DC accuracy ±0.05%, 50 kHz accuracy 0.2% (*1)**

Evaluating power conversion efficiency requires the ability to accurately measure power in every band, from DC to high frequencies. The PW8001 delivers exceptional measurement accuracy not only for 50/60 Hz, but also across a broad frequency band, including for DC and at 50 kHz. This allows it to accurately evaluate power conversion efficiency which often involves measuring multiple frequencies.

**- Sampling performance 18-bit, 15 MHz (*1)
- Noise Resistance (CMRR) 110 dB, 100 kHz* (*1)**

Evaluating power conversion efficiency requires the ability to accurately measure power in every band, from DC to high frequencies. The PW8001 delivers exceptional measurement accuracy not only for 50/60 Hz, but also across a broad frequency band, including for DC and at 50 kHz. This allows it to accurately evaluate power conversion efficiency which often involves measuring multiple frequencies.

**- 8-channel power measurement**

Increasingly, hardware like electric vehicle (EV) drive systems that use dual inverters and electric power interchange systems in smart homes are adopting multi-circuit designs in order to utilize energy effectively. A single PW8001 can measure 8 channels of power data, allowing equipment with 8 measurement points for power such as dual motors as well as other equipment with multiple circuits to be evaluated in one stroke.

**- Electrical angle measurement function**

In order to implement fine control of a permanent magnet synchronous motor (PMSM), it’s necessary to assess the motor’s characteristics under actual operating conditions. The PW8001’s electrical angle measurement function can perform voltage and current advance measurement, which is necessary in order to implement vector control of the dq coordinate system. The instrument can calculate Ld and Lq values from electrical angle measurements and ascertain motor parameters under actual operating conditions.

**- Dual torque value correction functions**

Torque meter measurement error has a substantial impact on motor analysis. The PW8001 can perform calculations using a correction table based on user-defined values for nonlinear compensation and friction compensation. The instrument can accurately analyze high-efficiency motors as well.

**- 1500 V DC CAT II, 1000 V DC CAT III (*3)**

Renewable energy generation systems are being engineered to use increasingly high voltages in order to reduce equipment construction costs and transmission loss. Evaluating generation systems requires instruments that are capable of high-voltage measurement. The PW8001 Input Unit U7001 can safely measure directly input high voltages of up to 1500 V DC (CAT II) and 1000 V DC (CAT III). (The Voltage Cord L1025, which can accommodate 1500 V DC [CAT II] and 1000 V DC [CAT III], is also available.)

**- High-accuracy measurement of high-frequency, low-power-factor power**

In order to improve power conversion efficiency, it’s necessary to assess power loss in reactors. The lower the reactor’s loss, the lower the power factor, making accurate measurement difficult. The U7005’s outstanding high-frequency characteristics and noise resistance make it an extremely effective tool for analyzing power loss in high-frequency, low-power-factor reactors.

Accuracy guaranteed for 6 months, multiply the 6-month accuracy reading error by 1.5 to obtain the 1-year accuracy.
