IMV CORPORATION’s latest addition to the A-series range has already achieved significant success with many blue chip companies taking advantage of this industry leading system.
The world leading A-series class A74 has a displacement of 76.2 mm p-p and a shock velocity rating of 3.5 m/s.
This makes the A74 capable of a 100 g, 11 ms shock pulse with an exceptional force rating of 74 kN sine and random.
The A74 is available with IMV’s award winning eco-technology.

*1) Force ratings are specified in accordance with ISO5344 conditions. Please contact IMV or your local distributor with specific test requirements.
*2) Power supply: 3-phase 200/220 V, 50/60Hz or 3-phase 380/400/415/440 V, 50/60 Hz. A transformer is required for other supply voltages.If other voltage is required, delivery date needs extra one month.
*3) Above 2000 Hz, the force rolls-off at a rate of -12 dB/oct.
*4)Width of EM8HM power amplifier is 1160 mm when the power supply is 200-240 V.
*5)Mass of EM8HM power amplifier is 1500 kg when the power supply is 200-240 V.
* The specification shows the maximum system performance. For long-duration tests, de-rating by up to 70 % must be applied. Continuous use at maximum levels may cause failure.
* 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.
