Remote Audio Meon LiFe - Manual (Page 2)

Rev 10/08/2012
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
The MEON LiFe includes an illuminated voltmeter on 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
4
battery modules (available in 20 Ah and 40 Ah
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 LiFePO
4
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 without fear of
overcharging or damaging the battery.
