OZSCR-2100
The OZSCR2x00 is a state-of-the-art, universal SCR firing and control board designed to simplify power system development and support. By making nearly every system parameter software configurable, it eliminates the need for multiple board variants and provides a single, flexible solution for diverse applications. With RS485 Modbus control and the Oztek Power Studio tool, setup, tuning, and field updates are fast and simple. Supporting up to 1000 VAC with dual-range line sensing, transformer-isolated firing circuitry, integrated closed-loop feedback, and advanced digital synchronization, the OZSCR2x00 delivers reliable performance across rectifiers, AC switches, and other power conversion systems.
Features
- One Universal Platform – Replaces dozens of control board variants—software-configurable parameters make it a single solution for multiple system needs, reducing costs and simplifying inventory.
- Flexible Power Compatibility – Handles up to 1000 VAC and 10–500 Hz with dual-range line voltage sense for both high- and low-voltage systems, making it suitable for global applications.
- Integrated Closed-Loop Control – Built-in DC voltage and current feedback enables precise regulation without additional external hardware, reducing system complexity.
- Easy Configuration & Field Updates – RS485 Modbus interface and Power Studio GUI make it simple to configure, tune, and update in the field, saving time and maintenance costs.
- Robust Synchronization & Accuracy – Digital Phase-Locked Loop ensures precise line tracking, wide dynamic range, and superior noise rejection for stable system operation.
- Multiple Control Modes – Supports phase angle, zero-cross, closed-loop, and burst control modes, with soft start/stop and fast inhibit functions for safe, flexible performance.
- Scalable & Expandable – Expansion interface allows multiple boards to be linked for complex systems controlling more than six SCRs.
- Proven Versatility – Ideal for single- and three-phase rectifiers, AC switches, and advanced multi-quadrant power conversion applications.
