Description
Product Overview
The GE DS3800NPPB1L1H is a high-reliability Power Supply Circuit Board designed for GE’s Mark IV Speedtronic turbine control systems. Engineered to provide stable DC power to critical components within the Mark IV chassis, this module ensures consistent operation of analog/digital I/O modules, microprocessors, and communication interfaces in mission-critical industrial environments. As a core component of the Mark IV ecosystem, the DS3800NPPB1L1H features redundant power paths and surge protection, making it ideal for gas/steam turbine control, oil & gas platforms, and heavy manufacturing applications.
Featuring four inductors, three large green capacitors, and eight transistors, the DS3800NPPB1L1H delivers +24V DC power with low ripple noise (<100mV). Its microprocessor-based architecture includes overvoltage/undervoltage protection, ensuring robust performance even in high-vibration or EMI-prone settings. The module interfaces with the Mark IV backplane via a 26-pin male connector, eliminating the need for external converters and reducing cabling complexity.
Constructed with industrial-grade components, the DS3800NPPB1L1H withstands extreme temperatures (-20°C to +60°C) and supports hot-swappable replacement without system shutdowns. Its front-panel LED indicators provide real-time status updates on power output and fault conditions, simplifying troubleshooting. By embedding this module into control architectures, operators gain uninterrupted power supply to optimize system performance and reduce unplanned downtime, making it an indispensable asset in high-reliability applications.
