Hioki benchtop power meters and power analyzers are best in class power measuring instruments for measuring single to three-phase lines with a high degree of precision and accuracy. The PW3337 series measure power on the full range of electrical equipment, from single-phase devices such as battery-driven devices and household electronics to industrial use and three-phase electrical equipment over 3 input channels. The power meters provide coverage from DC to inverter frequencies with support for voltages up to 1000 V and direct-input currents of up to 65 A, and can also measure currents of up to 5000 A using an optional current sensor. Key Features • Compatible with the SPECpower® benchmark for server power consumption SPECpower® is a registered trademark of Standard Performance Evaluation Corporation • Measure DC, and single-phase 2-wire to 3-phase 4-wire with 3-channel input • For development and production of motors, inverters, power conditioners, power supplies, and other devices • High-precision basic accuracy of ±0.1 % (*1) (*1) For complete details, please refer to the specifications • Wide frequency bandwidth of 0.1 Hz to 100 kHz or DC • High-current measurement up to 65 A of direct input • Harmonic measurement up to the 50th order according to IEC 61000-4-7 • High-accuracy measurement, even with a low power factor for no-load testing of transformers and motors • Built-in external sensor input terminals to measure up to 5000 A AC • Synchronize up to 8 units for multi-unit measurement • Create a 6-channel power meter by synchronizing two PW3337 units and using the free PC application
