Key Features and Advantages
Wide Voltage Range:
The IC3600SVZA1C interfaces with the Mark I/II system’s power supply to convert unstable input voltages (12-28V DC) into a precise, regulated output, ensuring consistent power delivery to critical control modules (e.g., thermocouple amplifiers, relay drivers) 27. Built-in surge protection and noise filtering enhance stability in high-interference environments.

Built-in surge protection and noise filtering enhance stability in high-interference environments.
Rugged Design:
Housed in a metal casing with screw terminals, the module is designed to withstand harsh conditions (operating temperature: -20°C to 70°C) and mechanical vibrations common in power plants and industrial facilities 2. The board features a large black transformer (part number 68A993055G1), five silver-red capacitors, and two blue potentiometers for manual voltage adjustments 2.

Installation and Maintenance
Installation Preparation:
- Verify input voltage compatibility (12-28V DC) and ensure proper grounding of the control cabinet.
- Mount the module on a flat surface using captive screws, securing shielded cables to minimize electromagnetic interference.
- Adjust the blue potentiometers to fine-tune output voltage if required, following GE’s Mark I/II system documentation 2.
Maintenance Recommendations:
- Regularly inspect for loose connections, capacitor swelling, or resistor discoloration, which may indicate thermal stress.
- Replace worn-out capacitors or transistors to maintain voltage stability.
- Maintain a spare IC3600SVZA1C for hot-swap replacement during scheduled downtime.
Product Warranty and Availability
The IC3600SVZA1C is backed by a 30-day to 3-year warranty from third-party suppliers (e.g., Ax Control, World of Controls), covering defects in materials and workmanship for refurbished units 27. GE’s original factory warranty does not apply. Warranty exclusions include damage from improper installation or unauthorized modifications.
Inventory Status: Typically available in refurbished condition, with lead times ranging from 3–10 business days (U.S. suppliers). For example, Ax Control lists the part number IC3600SVZA1CGBTc with availability upon request 2.
