High-Power H-Bridge Automotive Valve Driver/Tester

Designed specifically to drive automotive actuators such as EGR valves, turbo wastegates and throttle valves,  EmTroniX H-bridge driver accurately measures valves dynamic performances, electro-mechanical characteristics and offers advanced control methods.

This equipment is intended to be used on development test benches,  durability test stands and production lines.

The embedded software can execute a series of standard ​test schemes (sensor range identification, response-time and hysteresis) with integrated data acquisition/logging and test results processing.  It further includes an advanced position controller, a complex position/PWM profile generator and a test/profile sequencer primarily intended for durability purposes.​​​​​

Product advantages:


> The use of the latest FPGA technology allows an unprecedented control and sampling performances as required in today automotive component developments.

Easy to use

> All high-level functions are integrated into and executed by the driver at the reception of predefined commands sent through the CAN bus, making its integration and operation straightforward from the master device's standpoint.​​​



> This controller can be used indistinctively in engineering labs for component developments, on durability test benches to generate cycling profiles or on production lines for final quality checks.
