The WT100 series is designed with emphasis on solid performance, functionality, low cost and compact and is the latest digital power meter of YOKOGAWA. The WT110 is single phase model, and the WT130 is 3 phase model.

This model is made from several needs. For example, the request is realized by harmonic analysis function of the WT100 series that is to measure and analyze the harmonic distortion of current wave form because various harmonic-wave problems caused by distorted wave current. Another request is realized by integration function of both polarities that is to measure integrators for positive and negative polarities separately in the charge/discharge testing of battery-driven equipment.

Features:

• 0.25% of reading
• DC, 10Hz to 50kHz
• User calibration (by remote communications or manually)
• Insulation between voltage and current input terminals
  The double insulation design conforms to the safety standard IEC1010. All models are subjected to withstand voltage tests of 3.7 kV/50 Hz AC for one minute.
• New surge durability
  The specifications now include a durability of 2 kVrms, 300 Arms/1 cycle (20ms).
• Built-in harmonic analyzer
  The new built-in harmonics analyzer less than others in its class. This power meter, together with a clamp sensor. makes this meter ideal for power supplies.
