Power Conversion and Output Regulation
The board converts 24V DC backplane power into isolated 3.3V and 5V outputs. A high-frequency switching regulator provides efficient power conversion. The GE DS200UPLAG1A DS200UPLAG1ACB delivers clean power specifically for LAN communication cards. The 3.3V supply powers the main Ethernet processor and logic circuits. The 5V supply drives the physical layer transceivers and magnetics. Each output includes independent filtering for low ripple performance. Consequently, network cards receive stable power for error-free communication. A green LED indicates proper output voltage on both rails.
Protection Features and Fault Handling
The board includes overcurrent protection on each output channel. A hiccup mode circuit resets automatically after removing the overload condition. The GE DS200UPLAG1A DS200UPLAG1ACB also monitors its internal temperature continuously. It shuts down both outputs when the board exceeds 85°C. A red LED illuminates during any fault condition. The board recovers automatically when the temperature drops below 75°C. Input reverse polarity protection prevents damage from incorrect wiring.
Installation and Operational Guidelines
You must insert this board into a slot adjacent to the LAN communication card. The backplane supplies 24V DC power to the board automatically. The GE DS200UPLAG1A DS200UPLAG1ACB draws approximately 1.5 Amps from the 24V supply rail. You should verify adequate airflow around the board for cooling. The board operates reliably from 0°C to 60°C ambient temperature. It requires no external battery for normal operation. The board contains no user-serviceable fuses or adjustments. You should replace the entire board if any output fails regulation tests.
