STM Sinewave Inverter Drive Module IDM-8 (Grid Sharing) with CT & Hybrid Display Board

Product Description: The STM Sinewave Inverter Drive Module (IDM-8) is an advanced, high-efficiency SPWM (Sinusoidal Pulse Width Modulation) controller engineered for precision power electronics. Whether you are building a custom pure sine wave UPS, upgrading a solar inverter, or developing a grid-sharing power backup system, this complete kit provides professional-grade control and monitoring.

This comprehensive IDM-8 package includes a dedicated Current Transformer (CT) capable of safely monitoring loads up to 100A, ensuring your inverter operates efficiently within its limits. It also features a premium Hybrid Style Display Board equipped with tactile push buttons, allowing you to easily interact with the system, configure settings, and monitor real-time data such as voltage, current, and grid status. With user-selectable carrier frequencies and dual operating modes (Unipolar/Bipolar), this module is highly adaptable and ready to interface with your custom MOSFET or IGBT power stages.
