Three Phase Power Calibrator and Tester of Power Engineering Devices


C300B - Three Phase Power Calibrator and Tester of Power Engineering Devices

Data sheet

Three phase, class 0.02% and 0.05% power quality calibrator up to 120A (360A) and 560VAC with programmable power quality parameters. It makes possible to make automatic test of electricity meters, measurement transducers, current transformers and protection relays.


New generation of Three-Phase Power Calibrator with many easy to use functions for automatic calibrating and testing all type of measuring instruments and power engineering devices.

C300B is our newest calibrator series. We base on the newest technology and 25 years of experience in developing and manufacturing.


Our competence can give you only the best:

  • High performance: 3x560V, 3x120A (1x360A), class up to 0.02%
  • Huge output power and low weight: only 27kg (59lbs) in portable case
  • Advanced functions but easy to used
  • Manual operations and fully automatic procedures for calibrating and testing
  • Professional service and support (it doesn't matter if you have a complex or trivial issue)
  • Low price in comparison to the best performance


Read the Data sheet and the rest of the website to know all functions of the C300B Calibrator and Tester. You will find there information of using:


Wide range and high accuracy of outputs:

  • 3-phase voltages: 0.5000-560.00V
  • 3-phase currents: 1.000mA-120.000A, possible to bridged to 1-phase up to 360A
  • phase shift and angles between voltages: 0.00-360.00 degrees
  • output frequency: 40.000-500.000Hz or synchronization to power net frequency
  • impulse output: up to 200kHz to easy compare C300B to reference standard
  • binary outputs: 2 outputs for triggering external devices


Wide range and high accuracy of inputs:

  • impulse inputs: 2 inputs up to 200kHz for energy meters testing
