OZSCR-2000
The OZSCR-2000 is a universal, digitally controlled SCR control and firing board engineered to simplify SCR power system design while reducing cost and complexity. With nearly all system parameters software-configurable, it eliminates the need for multiple board variants, providing one flexible solution for diverse applications. Supporting AC mains up to 1000 VAC with integrated transformer-isolated firing circuitry, it ensures reliable synchronization, closed-loop control, and robust fault handling. Easy to configure via RS485 Modbus and the Oztek Power Studio GUI, it enables fast setup, field updates, and scalable performance for single- or multi-phase rectifiers, switches, and advanced power systems.
Features
- Universal Single-Board Solution – Replaces dozens of control board variants—every parameter is software configurable, reducing inventory and cost.
- High Flexibility Across Systems – Supports up to 1000 VAC, 10–500 Hz applications including rectifiers, AC switches, and multi-phase systems.
- Integrated Closed-Loop Control – Dedicated high-voltage and current feedback interfaces enable precise digital regulation without external hardware.
- Fast & Easy Configuration – RS485 Modbus interface and Power Studio GUI allow simple setup, real-time monitoring, and field updates.
- Robust Synchronization & Stability – Digital phase-locked loop ensures accurate AC line synchronization with wide dynamic range and noise rejection.
- Advanced Protection & Reliability – Intelligent fault handling minimizes downtime, while isolated “picket fence” firing circuitry enhances safety.
- Scalable Design – Multiple boards can be linked via the expansion interface to support systems with more than six SCRs.
- Broad Application Suitability – Ideal for single/three-phase rectifiers, AC switches, and advanced 4-quadrant rectifier designs.
