Product Description
The foc-4003b is an overvoltage regulator for aircraft DC electrical systems. This component monitors bus voltage and automatically removes alternator field excitation when voltage exceeds safe operating limits, protecting avionics and electrical equipment from damage. Installed in the alternator field circuit, the regulator responds to overvoltage conditions by interrupting excitation to prevent system overstress.
Installation follows aircraft wiring diagrams and manufacturer instructions per FAA AC 43.13-1B guidance. Verify compatibility with your aircraft's Illustrated Parts Catalog before installation.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
Frequently Asked Questions
What is the OVERVOLTAGE REGULATOR (P/N foc-4003b)?
The foc-4003b is an overvoltage regulator for aircraft DC electrical systems. This component monitors bus voltage and automatically removes alternator field excitation when voltage exceeds safe operating limits, protecting avionics and electrical equipment from damage.
What hydraulic fluid type is the foc-4003b compatible with?
Hydraulic component compatibility depends on the aircraft system design. Common aviation hydraulic fluids include MIL-PRF-5606 (mineral-based), MIL-PRF-83282 (synthetic), and Skydrol (phosphate ester). Verify the OVERVOLTAGE REGULATOR against your aircraft maintenance manual for fluid compatibility.
Does the foc-4003b come pressure-tested and certified?
