Description
AMX PSR5.4 Power Supply – 12VDC 5.4A with Phoenix Connector
The AMX PSR5.4 is a compact, wall-mounted power supply engineered to deliver clean, stable DC power to networked control devices and low-voltage studio peripherals. Its small footprint—measuring just 4.5" × 2" × 1.25"—fits neatly behind equipment racks, interface enclosures, or studio wall cavities without consuming valuable workspace. Built with industrial-grade protection circuitry, this supply provides rock-solid 12VDC power with minimal noise and drift, critical for keeping networked studio systems running reliably during sessions and recordings.
Power Delivery & Stability
Output reaches a maximum of 5.4A at 12VDC, sufficient for multi-device studio installations requiring moderate current draw. Ripple and noise remain controlled at 200 mV peak-to-peak at full load, ensuring exceptionally clean DC delivery to sensitive networked devices and control systems that demand low electrical noise to prevent ground hum, crosstalk, or digital interference in your signal chain.
Protection & Environmental Resilience
Integrated protection circuits guard against over-voltage, over-current, short-circuit, transient spikes, and thermal runaway—critical safeguards for studio setups running overnight sessions or on continuous standby. 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 studios and variable-temperature installations.

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.
