🔧 Technical Features
1. Advanced Control Algorithm
The PCD235A101 employs a proprietary PID (Proportional-Integral-Derivative) control algorithm with adaptive tuning capabilities. This ensures optimal excitation response under varying load conditions, minimizing voltage fluctuations and enhancing grid stability.
2. Redundant Design for High Reliability
Dual microprocessors and isolated power supplies provide fault tolerance, allowing the module to continue operating even if one channel fails. Critical applications benefit from seamless failover without interrupting generator output.
3. User-Friendly Interface
A backlit LCD display and tactile keypad enable local configuration and monitoring. Parameters such as voltage setpoints, excitation limits, and alarm thresholds can be adjusted without external software.
4. Modular Expansion
The module supports optional I/O expansion cards for additional analog/digital inputs (e.g., speed sensors, temperature probes) and communication interfaces (e.g., fiber-optic Ethernet).
