Description
Product Introduction
This GE F31X309SPCAGG1 is a special purpose power supply board for GE’s drive and excitation control platforms. The “SPC” designation identifies this as a Special Purpose Control/Supply board, providing isolated power for communication modules, memory expansion boards, and other specialty components. The “AGG1” suffix indicates a specific output configuration variant.
The board provides multiple isolated and regulated outputs with low-noise design, including +5 V, +3.3 V, +24 V, and +12 V in a specific configuration. It is used in systems requiring clean, isolated power for communication processors, memory modules, and other sensitive components.

Key Selling Points & Differentiators
- Multiple Isolated Outputs: Provides +5 V, +3.3 V, +24 V, and +12 V outputs for diverse module requirements.
- Low-Noise Design: Clean power for communication processors and memory modules.
- Enhanced Status Indication: Additional LED indicators for each output with color-coded status.
- Quantified Testing Protocol: We test each output under load for 8 hours. Ripple is measured with an oscilloscope. Isolation is verified with high-potential testing.
- Warranty & Support: 2-year functional warranty with detailed output configuration documentation.
Frequently Asked Questions (FAQ)
Q1: What is the difference between the SPCAGG1 and the standard PCA series boards?
A: The standard PCA boards provide general-purpose power with standard outputs. The SPCAGG1 is a special purpose board with multiple isolated outputs (+5 V, +3.3 V, +24 V, +12 V) for communication and memory modules.
Q2: Which modules require the additional +3.3 V or +12 V outputs?
A: The +3.3 V output is typically required by advanced communication processors and FPGA-based modules. The +12 V output may be required by certain specialty I/O modules or analog signal conditioners.
Q3: Does the SPCAGG1 have the same ripple specification as the fiber-optic power boards?
A: The SPCAGG1 has a ripple of less than 30 mV peak-to-peak. For fiber-optic transceiver power, the SPCAFG1 variant has a lower ripple specification (20 mV).
Q4: Does this board have overcurrent protection?
A: Yes, all outputs have overcurrent and short-circuit protection with auto-reset. The protection response is less than 50 ms.
Q5: What is the lifecycle status of the SPCAGG1?
A: This board is very rare. We have a very small batch of new surplus units. If your system requires the special purpose power configuration, we strongly recommend securing a spare. We do not expect to source more of this variant.
