The Remote Audio MEON LiFe™ is a single-rackspace, self-contained power system that silently provides up to 18 Amps of 12 Volt DC and 20 Amp-hours of internal Lithium-Iron-Phosphate battery backup to ten standard 4-pin outlets in a module weighing less than 13 pounds. The chassis is constructed of durable and lightweight powdercoated aluminum, and its removable mounting ears can be reversed to allow mounting in a variety of configurations. The MEON LiFe™ includes an illuminated voltmeter and connects to Remote Audio's RM or RS accessories which enable remote ON/OFF capability and/or battery monitoring. Two integral USB output jacks located on the front panel will charge or power standard 5VDC USB devices.
The MEON LiFe™'s illuminated single-button ON/OFF system activates when a user engages it for approximately 2 seconds. This required hold-time helps prevent accidental power up or down of the system. When the unit receives 90VAC-264VAC power, the power button LED glows GREEN and current is provided by a low-noise AC-DC power supply rated to 18A. Simultaneously the internal battery is taken out of circuit and charged via its own dedicated internal charger capable of providing 5A of charging current. When AC power is unavailable or interrupted, the battery seamlessly takes over and the power button LED glows RED. When AC power is restored, the AC-DC power supply takes over again, the battery resumes charging, and the power button glows GREEN. Thus, the color of the LED button informs you of the origin of power to the MEON at all times. The indicator button is mirrored on the front and back of the unit for visibility regardless of the unit's position.
Internal LiFePO4 Battery
Lithium-Iron-Phosphate batteries are a relatively new technology and share common properties with all Li-Ion technologies like lower weight and smaller size than equivalent capacities in other chemistries (such as Lead Acid and NiMH). However, a key advantage of LiFePO4 when compared to other Li-Ion types is its superior thermal and chemical stability. LiFePO4 cells are virtually incombustible (even when mishandled during charge/discharge), and they can handle much higher temperatures without degrading in performance. LiFePO4 also offers a longer calendar life and higher peak-power rating than other Li-Ion designs, and it contains no toxic heavy metals.
The MEON LiFe™'s internal battery is polyfuse-protected for a maximum output of 14A, and is protected from over-charge and over-discharge conditions.
There are ten DC power outlets on the back of the MEON LiFe™ each wired in the standard 4-pin XLR configuration of PIN 4 +, PIN 1 -. Each outlet has auto-resetting breakers to protect against overload. Three of the outlets are heavy-duty connectors each capable of supplying 9A. The remaining seven output connectors are rated for 5A each. A master 18A breaker protects against combined overload when multiple outlets are used. An entire sound cart (drawing 9A or less) can be powered through a single XLR outlet if desired. For example, if power distribution to the devices on a cart is done through a Remote Audio BDS or HOT BOXv2, a single 9A XLR outlet on the MEON LiFe™ can power multiple devices. Alternatively, each device being powered can be cabled directly to the MEON LiFe™'s ten outlets.
The MEON LiFe™ is programmed to shut down when the output voltage reaches approximately 10V as indicated on the front display. This is to prevent over-discharge of external supplemental Lead Acid batteries that may not have their own built-in protection.
Two USB connectors are available on the front of the MEON LiFe™ to charge or power 5VDC USB devices (such as smartphones, digital transcription recorders, etc). The two ports have a total combined capacity of 2A @ 5V (10W) and are regulated and protected from short circuits. These USB jacks are configured in such a way to charge Apple devices at the fastest rate (highest current) available. For example, an Apple iPad will draw approximately 2A peak from one USB port. Smaller Apple devices, such as iPhones will draw approximately 1A. Thus, it may not be possible to charge an iPhone and and iPad simultaneously due to the 2A current limit from the MEON LiFe™'s USB ports.
