Vibration Controller

K2

K2

Common hardware that supports all vibration tests.

The K2 controller provides the precision and repeatability required to test with confidence during both product development and series production.
Its hardware and software were developed in-house, giving IMV full design control of this important part of a vibration system.
The K2 system offers enhanced functions and operability based on the most advanced technologies and incorporating feedback from our customers for both single- and multi-axis shaker applications.

■Precision control capabilities
K2 employs high-resolution 24 bit A/D and D/A converters to achieve high-precision, repeatable control.
■Safety interlock function
A hardware mute function operating independently of software provides complete protection for the vibration system and payload.
■E-mail notification
Remote sites can be notified by email of any abnormality during testing or termination of a test.
■Data saving
Test definitions and results are output from the K2 in CSV format.
