GE DS3820SVRA Static Voltage Regulator Assembly

The GE DS3820SVRA is a Static Voltage Regulator Assembly for the Mark IV Speedtronic turbine control system. Its primary purpose is to maintain a stable output voltage for critical electronic components, protecting them from power quality issues such as voltage fluctuations, sags, or surges.

Technical Breakdown 🧠

This module is a foundational component of the control system’s power infrastructure, ensuring reliable operation of the electronics.

• • Voltage Regulation: The DS3820SVRA receives an input voltage that may be unstable or subject to variations and uses solid-state electronic components to provide a precisely regulated, constant output voltage. This is critical for the reliable function of sensitive components like processors and analog I/O boards, which require a stable power source to operate correctly.

• “Static” Operation: The term “static” highlights that this device operates using electronic components without any moving parts. This provides a significant advantage in industrial environments, offering high reliability, zero mechanical wear, and a very fast response time to correct voltage deviations.
• Power Conditioning: In addition to voltage regulation, the assembly also provides power conditioning. It filters out electrical noise and transients that are common on industrial power lines, delivering a clean power signal that is essential for the integrity of the control signals.

Applications 🏭

The DS3820SVRA is a critical component used in Mark IV control panels to:

• Protect Sensitive Electronics: Shields processors, memory, and I/O cards from damaging voltage spikes and dips.
• Ensure System Stability: Guarantees a stable power supply, which is a prerequisite for accurate and reliable control system operation.
• Support High-Availability Systems: Reduces the risk of unexpected shutdowns or system resets caused by power supply irregularities.
