  • *1 Random force ratings are specified in accordance with ISO53 44 conditions. Please contact IMV or your local distributor wi th specific test requirements.
  • *2 Power supply: 3-phase 220/480 V, 60 Hz. A transformer is required for other supply voltages.
  • *3 In case of 480 V
  • *4 Above 2000 Hz, the force rolls-of f at a rate of -12 dB/oct.
  • *5 Spec described above is in case of 60 Hz. Dimension is changed in case of 50 Hz.
  • *6 E/L is required for exporting the shaker system of over 11,240 lbf Sine force.
  • *7 In case of high velocity option
  • * The specification shows the maximum system performance. For long-duration tests, de-rating by up to 70% must be applied.
  • * In the case of Random vibration test, please set the test definition of the peak value of acceleration waveform to be operated less than the maximum acceleration of Shock.
  • * Frequency range values vary according to sensor and vibration controller.
  • * Mass and dimensions may change for CE-marked systems.
