Description
AMX PSR7-V Power Supply – 12VDC 5.5A with Phoenix Connectors
The PSR7-V is a compact, rack-mounted power distribution solution built for live sound, networked audio, and AV installations where reliability matters. Its modular V-style design fits efficiently into 1 RU of rack space, and three units can be mounted side-by-side to consolidate power management without consuming excessive real estate. Built to perform night after night in touring rigs and permanent installations, this supply delivers consistent 12VDC power with comprehensive protection circuitry that keeps your system running.
Power Delivery & Protection
The supply outputs 5.5 amps of 12VDC with switching-regulated, overload-protected circuitry that guards against over-voltage, over-current, short-circuit, transient, and thermal faults. A green LED indicator confirms DC output status within the fault-tolerant range, allowing quick visual verification of supply health on the fly—no test equipment needed.
Installation & Connectivity
Three 3.5 mm phoenix connectors with retention screws provide secure, tool-free connections that resist vibration and accidental disconnection—critical for touring and festival rigs. The unit supports both rack mounting via V-style module tray and surface mounting via included brackets, making it adaptable to venue layouts and temporary setups.

Frequently Asked Questions
What devices can this power supply run?
The PSR7-V outputs 12VDC at 5.5 amps and is designed for professional AV equipment, networked audio systems, control modules, and other 12V DC gear specified for this voltage and current range. Its three phoenix connectors allow you to split power among multiple devices or run a single load; check your device specs to confirm 12VDC compatibility and total current draw under 5.5A.
How is it mounted, and will it fit my rack?
The PSR7-V occupies 1 RU of rack space and ships with both a V-style module tray for standard rack rails and surface-mount brackets for non-rack installations. Three units can be mounted side-by-side if you need to expand power distribution without consuming multiple RU slots.
What protection does it offer?
The supply includes switching-regulated circuitry with comprehensive protection against over-voltage, over-current, short-circuit, transient surges, and thermal faults. A green LED indicator shows real-time fault-tolerant status, letting you verify supply health at a glance without extra test gear.
Are the connectors secure?
Yes—three 3.5 mm phoenix connectors with retention screws provide tool-free, vibration-resistant connections that prevent accidental disconnection during live events or in transit. The screw terminals ensure a solid, repeatable connection every time.
Is this suitable for portable or mobile use?
No—the PSR7-V is engineered for fixed installations and stationary studio or live-sound rigs. Its compact rack footprint and protection features are built for mission-critical, permanently mounted audio systems rather than portable setups.
