tDrive Lite is a versatile engine controller for electronic or mechanical management, designed to provide full control, advanced protection, and real-time monitoring.

It supports both open-loop and closed-loop operation, multi-stage acceleration ramp control, critical sensor monitoring, and automation of key functions such as starting, preheating, and alarms. Its intuitive interface, diagnostics capabilities, and IP67-rated protection make it a reliable solution for demanding environments.

With configuration available via front panel or password-protected software, and optional modules like the RelayPack, tDrive Lite combines control power, operational intelligence, and industrial-grade durability.
