The MEON LiFe (internal Lithium-Iron-Phosphate [LiFePO4]
battery), is a self-contained power system that 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 all in a single, silent, 1-rackspace module weighing
less than 14 pounds. The chassis is constructed of durable
and lightweight powdercoated aluminum, and the removable
mounting ears can be adjusted and reversed to allow
mounting in a variety of configurations. An illuminated
voltmeter is included, and the MEON LiFe can connect to
Remote Audio's RM or RS accessories which enable remote
ON/OFF capability and battery monitoring. Two USB output
jacks are available at the front panel for charging or
powering standard 5VDC USB devices.

Description

The MEON LiFe employs an illuminated single-button
ON/OFF system which requires the user to hold the button
for approximately 2 seconds. This helps prevent accidental
power cycling of the system. When the unit is receiving
90VAC-264VAC power, the power button glows GREEN,
and current is provided by a low-noise AC-DC power supply
able (up to 18A). When AC power is present, the internal
battery is bypassed from the outputs and charged via its own
dedicated, internal, 5A charger. When AC power is
unavailable or interrupted, the battery seamlessly takes
over. The power button then glows RED. When AC power is
restored,

the AC-DC supply takes over again, the battery

resumes charging, and the power button glows GREEN

--conveying the origin of your power at all times.

Mounting the MEON LiFe

The MEON LiFe can be mounted in a number of ways:

In a standard 19-inch single rack space. The mounting ears
can be positioned so that connectors face inward or
outward. An ON/OFF button and “Charge Status” LED are
on both sides of the MEON LiFe, to facilitate front or back
mounting. The mounting tabs are also adjustable so that
the connectors can be recessed safely out of the way.

The mounting ears can be removed so that the MEON can
be placed on a horizontal surface such as a cart shelf.

Internal LiFePO4 Battery

The MEON LiFe’s Lithium-Iron-Phosphate (LiFePO

4)

batteries share a common property with all Li-Ion
technologies in that they are lower weight and smaller size
than equivalent capacities in other chemistries, such as
Lead Acid and NiMH. However, a key advantage of LiFePO

4,

when compared to other Li-Ion types, is its superior thermal
and chemical stability. LiFePO

4 cells are virtually

non-combustible (even if mishandled during
charge/discharge) and can handle much higher
temperatures without degrading in performance. LiFePO
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.

Output Connectors

There
LiFe, wired in the standard 4-pin XLR configuration of PIN

are ten DC power outlets on the back of the MEON

4+, PIN 1-. Each outlet has auto-resetting breakers to protect
against overload. Three of the outlets are heavy-duty
connectors, capable of supplying 9A each.

The remaining seven output connectors are rated for 5A
each. A master 18A breaker protects against combined
overload when multiple outlets are used. A typical 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 the Remote Audio BDS,
HOT BOXv2, or HOT STRIP, a single 9A XLR outlet on the
MEON LiFe may be used to power multiple devices.
Alternatively, each device being powered can be cabled
directly to the MEON LiFe's ten outlets.

USB Connectors

Two USB connectors are 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. Therefore, though an iPhone and iPad
may be plugged into the USB ports simultaneously, they may
need more time to charge in this configuration due to the 2A
current limit from the MEON LiFe's USB ports.

Voltage Meter

MEON LiFe includes an illuminated voltmeter on the

The
front panel which indicates the voltage of the output
connectors when the MEON LiFe is turned ON. The meter is
calibrated at the factory for accuracy. However, there may be
some temporary drift in readings based on ambient and
internal temperature, typically less than 5%. Additionally, if
an RM is connected for remote metering, there may be slight
differences (less than 10mV) between the meter voltage
readings due to the high resolution of the meters.

“TEST” Button

When the MEON LiFe is turned OFF, the TEST button on the
front panel can be pressed to show the voltage of the battery.

If AC is present, TEST will show the voltage of the internal
battery and charger combination. If AC is not present, TEST
shows the actual voltage of the battery, including any
connected supplemental batteries. This is a handy way to
check the status of your batteries without having to turn on
the MEON LiFe, and without having to turn on connected
equipment.

Supplemental Batteries and Charging

An input connector (4-pin XLR Male) is provided on the back
panel for connecting an external Lead Acid battery or
Remote Audio’s supplemental, single rackspace, “Extra
LiFe” LiFePO
versions). The XLR is wired in the configuration of PIN 1&2

-, PIN 3&4 +. (To improve reliability and reduce voltage drop,
the contacts are doubled.) Therefore, if the user wires their
own input cables, it is recommended to connect pins 1-2 and
3-4. The supplemental battery can be used to extend
runtime when AC is unavailable. When an external battery is
connected to this input XLR connector, it will charge when
AC is present just like the internal battery. The internal
charger is a “smart charger” and will not over-charge a Lead
Acid battery or LiFePO4 battery. It is important to remember
that adding a supplemental battery in this fashion will
increase the overall charge time of the system.
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.
The indicator labeled "Charge Status" verifies that charging
is taking place at either the full rate (red) or topping rate
(green). When the MEON LiFe is fully discharged, it will
recharge fully in approximately 3 hours. Due to the charge /
discharge controller circuitry, the MEON LiFe can remain
connected to AC power indefinitely
overcharging or damaging the battery.

Connecting the RM/RS

The MEON LiFe can be used in conjunction with Remote
Audio's RM (Remote Meter) or RS (Remote Switch). The
RM allows remote monitoring of voltage and current (Amps)
as well as remote ON/OFF control of the MEON LiFe. The
RS provides remote ON/OFF control and a low voltage
indicator. Connect either device's 6-pin connector via the
"Remote" port on the connector panel of the MEON LiFe.

See the RM and RS user guides for more details.

Does the MEON LiFe use fans?

No. The MEON LiFe was designed to employ convection
cooling specifically because cooling fans cannot be tolerated
on a very quiet sound stage. It is best to mount the MEON
LiFe with some free space above the chassis to allow proper
cooling when using AC power. The MEON LiFe has vent
slots in the sides of the chassis that should remain
unrestricted during operation to facilitate cooling while
supplying maximum rated current.

Noise and Shared Power Systems

It is possible to have unwanted audible noise through a
common (shared) power source typically due to “ground
loops” from the various internal power supplies of the
devices being powered. To optimize your system, it is
recommended to use line level signals instead of mic level
signals whenever practical. Also, turn phantom voltage off of
all preamp inputs that are connected to non-microphone
devices. If noise is still heard, unplug one device at a time

the MEON noticing any change in noise associated

from
with the removal of each device. If the noise goes away after
unplugging a particular device, try powering that device with
a separate battery. If using a separate battery causes the
noise to go away, then the problem is a ground loop
associated with the combination of a common power source
and audio grounding schemes. Be aware that this noise will
not be removed with "LC" filters found in some cart power
supplies. To remove the noise, here are four options for
interrupting the ground loop:

1) Use a separate battery for the offending device.

2) Try different grounding/floating schemes with the audio cables.

3) In devices that use a single 9V battery, use an isolating 9V
battery eliminator such as the one made by Lectrosonics.

4) Use a power isolator cable such as the Remote Audio Juicer
cable.

Important Information about Internal Battery Protection

In addition to the resettable circuit breakers on each output,
the MEON LiFe’s battery is internally protected from
overload and short circuits. In some cases, a sudden dead
short at an output may activate the protection circuit of the
internal battery. In this condition, the MEON LiFe will not
come back on until external power is applied, either by
plugging into AC or, if AC is not available, by applying a
charged 12V battery to the external battery input.
