Description
AMX PSR5.4 Power Supply – 12VDC 5.4A with Phoenix Connector
The AMX PSR5.4 is a compact, wall-mounted power supply built for reliable operation in fixed installations and networked AV environments. Its small footprint—measuring just 4.5" × 2" × 1.25"—fits neatly behind equipment racks or wall cavities without consuming valuable space. Built with industrial-grade protection circuitry, this supply delivers stable 12VDC power to networked control devices and low-voltage AV peripherals with minimal noise and drift.
Power Delivery & Stability
Output reaches a maximum of 5.4A at 12VDC, sufficient for multi-device installations requiring moderate current draw. Ripple and noise remain controlled at 200 mV peak-to-peak at full load, ensuring clean DC delivery to sensitive control systems and networked devices that demand low electrical noise for reliable operation in live and installed venues.
Protection & Environmental Resilience
Integrated protection circuits guard against over-voltage, over-current, short-circuit, transient spikes, and thermal runaway—essential safeguards for unattended or mission-critical installations where downtime isn't an option. The unit operates reliably across 32°F to 104°F in active service, with extended storage tolerance from –4°F to 176°F, making it suitable for both climate-controlled venues and variable-temperature environments on the road.

Frequently Asked Questions
What is the maximum current output, and is it enough for my system?
The PSR5.4 delivers a maximum of 5.4A at 12VDC, making it suitable for multi-device installations and networked control systems that require moderate current draw. If your application needs sustained high-current draw or power for portable equipment, confirm your total device amperage against this spec before purchasing.
What kind of connector does it use, and are screws included?
The unit features a 3.5 mm Phoenix connector with retention screws included, allowing secure, tool-free connections typical of professional AV and control installations.
Will this work worldwide, and what input voltage does it accept?
Yes—the PSR5.4 accepts universal input from 100–240 VAC (±10%) at 47–63 Hz, making it suitable for use in any country without a step-down transformer. Input current draws less than 2A at 100 VAC and less than 1A at 230 VAC at full load.
What protection does this supply have against electrical faults?
The PSR5.4 integrates comprehensive protection circuitry against over-voltage, over-current, short-circuit, transient spikes, and thermal runaway, making it safe for unattended or mission-critical fixed installations.
How small is it, and will it fit in my rack or installation space?
It measures just 4.5 inches by 2 inches by 1.25 inches and weighs 1.1 pounds, allowing it to mount discreetly behind equipment racks, in wall cavities, or in tight installation spaces without consuming valuable real estate.
