The PW3336 series (2-channel) and PW3337 series (3-channel) are easy-to-use, high-accuracy power meters that deliver current measurement of up to 65 A with direct input as well as built-in harmonic analysis functionality, all with accuracy that exceeds that of previous HIOKI power meters.
The new PW3336 and PW3337 three-phase power meters offer the fine precision, direct input functionality and large current sensing capabilities required to increase efficiency and minimize power consumption, especially in areas of motor, inverter and power conditioner evaluations.
These Hioki digital power measuring devices, when used with an optional clamp sensor, can also measure up to 5000A AC. In addition to built-in harmonic analysis functionality, the PW3336 and PW3337 Power Meters provide GPIB, LAN, D/A output and other interfaces to better accommodate a variety of testing situations.
