MAR-90580003 vs MAR-90580004 — Compare
Martin Exterior AC-Feeder vs Martin Exterior DC-Feeder
The AC-Feeder connects directly to line voltage and emphasizes corrosion resistance (C-5 rating) for permanent architectural installations, while the DC-Feeder accepts 48VDC input and prioritizes power efficiency with multi-mode consumption states for touring and temporary deployments. Choose AC-Feeder for fixed outdoor venues in harsh salt-air environments; choose DC-Feeder for mobile/rental operations where low idle power and extreme temperature range matter.
No sales tax on orders shipped outside California — total cost beats national retailers that charge sales tax in nearly every state.

Frequently asked questions
What power input do these feeders require?
The AC-Feeder connects directly to line voltage for permanent installations. The DC-Feeder accepts 48 VDC +/- 4% input from standard power supplies, making it better suited for touring rigs.
Which feeder is better for coastal outdoor venues?
The AC-Feeder carries a C-5 High corrosion rating specifically engineered for salt-air and chemically aggressive environments, making it the clear choice for permanent seaside or industrial installations.
How do they differ in power efficiency?
The DC-Feeder offers three consumption states: 110W at full load, 5.0W idle, and 2.2W hibernation. The AC-Feeder specs focus on environmental durability rather than detailed power-draw modes, better suited for always-on architectural deployments.
What is the operating temperature range?
The DC-Feeder explicitly supports -30°C to +55°C, covering extreme climates. The AC-Feeder does not specify a temperature range in the provided details, relying on its IP66 and IK08 ratings for durability.
