. Description
AMX PSR7-V Power Supply – 12VDC 5.5A with Phoenix Connectors
The PSR7-V is a compact, rack-mounted power distribution solution purpose-built for studio and networked audio systems. Its modular V-style design occupies just 1 RU of rack space, and three units can be mounted side-by-side to consolidate power management for multi-device sessions without consuming excessive real estate. Engineered for reliability in recording and production environments, this supply delivers consistent 12VDC power with comprehensive protection circuitry that safeguards connected equipment through long studio sessions.
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 during setup and troubleshooting without additional test equipment.
Studio Integration & Connectivity
Three 3.5 mm phoenix connectors with retention screws provide secure, tool-free connections that resist vibration and accidental disconnection—critical for stable rack-mounted setups where cables run behind gear. The unit supports both rack mounting via V-style module tray and surface mounting via included brackets, making it adaptable to various studio configurations and workflow needs.

Frequently Asked Questions
What does B-Stock mean for this power supply?
B-Stock means this unit is fully functional and tested to specification, but may have minor cosmetic imperfections or packaging wear. Performance and reliability are identical to new.
What devices can I connect to this power supply?
The PSR7-V outputs 12VDC at 5.5 amps via three 3.5 mm phoenix connectors, suitable for networked audio devices, control modules, AV processors, and other equipment that requires secure 12V DC power. Check your device's power requirements to ensure compatibility.
How is this different from the Meanwell RSP-500-12 or similar supplies?
The PSR7-V is optimized for compact rack installations with its 1 RU footprint and three connectors in a single unit; comparable units like the Meanwell RSP-500-12 offer higher power but require more rack space. Choose the PSR7-V if you need distributed, modular power distribution in tight racks.
Can I mount multiple units together?
Yes, up to three PSR7-V units can be mounted side-by-side using V-style module trays, allowing you to consolidate multiple 12V circuits without excessive rack real estate. Surface-mount brackets are also included for flexible installation.
What protection features does this supply have?
The PSR7-V includes switching-regulated protection against over-voltage, over-current, short-circuit, transient, and thermal faults, plus a green LED indicator that shows when DC output is within the fault-tolerant range, eliminating guesswork during installation and troubleshooting.
