Yokogawa has introduced an enhanced version of its best-selling WT300 Series of compact fifth generation digital power meters, featuring higher accuracy, new measurement functionality and improved connectivity, including Modbus/TCP capability to aid integration into production environments.
The new series has a basic power accuracy of ±0.15% at 50/60Hz on all measurement ranges, along with a bandwidth of DC and 0.1Hz to 100kHz. The influence of power factor is also greatly reduced: at low power factor the accuracy is twice that of the previous models (±0.1% of apparent power S).
The WT300E series covers a broad range of input currents from a few milliamps to 40A RMS, making it equally suitable for measuring low currents in standby power testing to the high currents encountered in induction cookers.
