La description

The WT300 series of digital power meters are the fifth generation of Yokogawa's best-selling compact power meters: instruments that play a key part in ensuring optimum standards of energy efficiency and conservation by measuring the power consumption of electrical equipment. Combining accurate and reliable power measurement over a wide power range with flexibility, ease of use and a choice of communication interfaces, these instruments will help developers, engineers and manufacturers of electrical equipment to ensure that their products comply with emerging IEC and EN standards and increasingly complex and stringent specifications on energy efficiency. They provide ideal measurment solutions for various applications ranging from stand by power measurement to Energy star for various manufacturers such as domestic white goods, battery chargers, lighting systems.
The WT300's wide range of funcations and enhanced specifications allows to handle all the measurement applications from low-frequency to high frequency inverters using a single power meter. Accuracy with fast display and update rate: The WT300 series with the fast display and date update rate of Max. 100ms offers the customer a short tact time in their testing procedure. The basic accuracy for all input ranges is 0.1% rdg + 0.1% rng (50/60Hz) and DC 0.1% rdg + 0.2% rng (0.2% + 0.2% for 40A). Simultaneous Measurement: U/I/P/Freq/Integ(+/-)/Harmonics components/ THD with max. 100ms cycle. In addition to standard power measurements, the WT300 offer a wide range of harmonic measurement capabilities, including the ability to carry out simultaneous measurement of normal power parameters such as RMS, mean or DC power along with measurement of harmonics up to the 50th order. As a result, overall measurement times are reduced, allowing users to allocate their effort and time to other tasks. First in Class: Auto ranging function available in selected ranges. The auto-range function is used to select or change the range automatically in specific ranges. This results in shorter range changing times, allowing more quick and efficient testing. First in Industry: Auto Ranging Function For Integration Measurement. Typically, when power meters operate in an integration mode to measure power consumption and standby power, the measuring ranges need to be fixed. However, if the level of the input exceeds the maximum of the selected range, the test will need to be repeated. The WT300 Series has a high speed automatic ranging capability in integration mode, which removes the need to repeat any test. Bandwidth: DC and 0.5Hz to 100 kHz (WT310HC is up to 20 kHz for 40A). Direct Input: Maximum direct input up to 600V and 20A, or 40A (incase of WT310HC). The wide current input range gives the customer options to use the WT300 series from as low as 50 micro-Amps to 40Arms. High-speed data update (up to 10 readings per second.)''
