Single-Phase Power Meter with All-Round Capability from AC/DC Standby to Operating Power Power data and harmonic data — all measured simultaneously All measurement data are internally processed in parallel simultaneously. Even when waveforms have mixed AC/DC components – half-wave rectification waveforms for example – the individual components can be measured simultaneously. The PC communication application further enables 180 or more measurement parameters to be acquired simultaneously. The PW3335 measures harmonics up to the 50th order. Use it for evaluation and development of power sources for home appliances and other electrical equipment. Simultaneously display the effective voltage and total harmonic distortion (THD) on the screen. For THD computation, any maximum harmonic order can be specified. Power consumption Wh(+) Regeneration power Wh(−) Built-in harmonic measurement Basic accuracy of ±0.1%*, the highest in its class Precisely measure power to determine the energy-saving performance of electrical products. Your measurements are underpinned by its reliability and accuracy. The PW3335 Power Meter delivers a range configuration that lets you measure extremely low power levels with a margin to spare. Accuracy can be set from 10 μA and up for current, and 0 W and up for effective power. Perfect for measurements according to IEC62301 and other standards. Greater accuracy for standby power ±0.1% ±0.1% Standby mode Off mode Current waveforms in the switching power supply or at the primary-side of inverters become steep and often exceeds the fundamental range, preventing them from being accurately measured. The PW3335 resolves these issues by offering a crest factor of 6, allowing it to measure accurately even when the waveform peaks are high relative to its range. The effective power value may be affected in situations with low power factors, such as measurement of standby power or unloaded operation of transformers and motors. The PW3335 reduces the power factor effect to less than a half of that available in legacy models. Peak value of up to 600% of the range, supporting crest factor of 6 Power factor effects of no more than ±0.1% f.s. Peak = 6 mA RMS = 1 mA CF = Peak/RMS = 6 Example of half- wave rectification waveform Example of distorted waveform containing harmonic component Use for evaluating the input and output of secondary batteries in EVs, etc., and for measuring the sold power of solar panels. Power consumption and regeneration (recharging) power can each be measured separately. Capture maximum and minimum values such as inrush current waveform peak values and maximum consumed power.

210 mm (8.27 in) 100 mm (3.94 in) Diverse and Powerful Functionality Measure power in accordance with international standards Measure integral power of equipment that operates intermittently or has a large power variation The PW3335 is engineered to comply with important international standards, including IEC62301 for electrical power consumption in standby mode and the ErP Directive or Energy Star standard. It can also be used to find the special parameters required by the standards – such as THD, CF, and MCR. THD (total harmonic distortion) CF (crest factor) MCR (maximum current ratio) Indicates the total harmonic components in an AC waveform. Also known as the peak-to-rms ratio, the ratio of the waveform's peak value to its effective value. Evaluation index of the current, calculated from the crest factor and the power factor. Auto-range integration A function whereby the device jumps automatically to the optimal current range for the consumed current as it measures and integrates the values. Power integration can be carried out on separate ranges, enabling measurements for individual modes in equipment that has fluctuations in power levels. Time-averaged effective integral power Use this feature to measure the power of equipment that operates intermittently or is under cycle control. Average power is calculated from the integral value of the fluctuating power.Example of intermittent operation Example of cycle control 25 mm (0.98 in) 23 mm (0.91 in) 52 mm (2.05 in) 32.5 mm (1.28 in) 21.5 mm (0.85 in) 22 mm (0.87 in) 220 mm (8.66 in) Download free software for creating IEC62301-compliant reports from the Hioki website.

Display range Time Average Current ±0% to ±612% of the range (Has polarity when using the DC rectifier.) Time Average Active Power ±0% to ±3745.4% of the range (Has polarity) Functional Specifications Auto-range (AUTO) Automatically changes the voltage and current range according to the input. Range up: The range is increased when input exceeds 150% of the range or when the peak is exceeded. Range down: The range is decreased when input falls below 15% of the range. However, the range is not decreased when the peak is exceeded at the lower range. The input level is monitored, and the range is switched over multiple ranges. Range select can be used to disable ranges so that they are not selected. Range select Selects whether to enable (turn on) or disable (turn off) individual voltage and current ranges. Enabled (use): Ranges can be selected with the range keys. Range switching occurs using auto-range operation. Range switching occurs during auto-range integration. Disabled (do not use): Ranges cannot be selected with the range keys. Range switching does not occur using auto-range operation. Range switching does not occur during auto-range integration. Zero-cross filter’s threshold level Sets the zero-cross filter’s threshold level for voltage and current ranges. Set from 1% to 15% (in 1% intervals). Synchronization occurs when the percentage level set for each measurement range is exceeded. Averaging Averages the voltage, current, active power, apparent power, and reactive power. (Other than harmonic measurement parameters.) The power factor and phase angle are calculated from averaged data. Averaging is not performed for parameters other than those listed above. Method: Simple averaging Number of averaging iterations and display update interval Scaling (VT, CT) Applies user-defined VT and CT ratio settings to measured values. VT ratio setting range OFF (1.0), 0.001 to 1000 CT ratio setting range OFF (1.0), 0.001 to 1000 Hold
