Features:
Standard transfer relay: The standard 20 amp transfer
relay will pass AC power through
the inverter when using shore or
generator power.
Versatile mounting: Mount the
MMS1012G on a shelf, bulkhead, or
even upside down.
Fan cooled: The MMS1012G is fan
cooled, enabling the unit to work
well in confined spaces. If the
inverter does exceed its temperature
limits, it will automatically shut
down and then restart when it
cools down.
Low/high battery protection: If your battery voltage reaches
below 10 VDC or above 15.5
VDC, the MMS1012G will
automatically shut down.
Current overload protection: The
MMS1012G will automatically shut
down if its output wattage
is exceeded or it detects a short in
the wiring, saving the unit from
costly damage.
Convenient switches: The MMS1012G comes with an on/off frontmounted
switch with an easy-toread
LED indicator.
Circuit breaker protection: Comes with built in input
and output circuit breakers for ease
of installation.
Battery temp sensor: The standard
battery temperature sensor monitors
temperatures from 0 - 50° C
Safe and reliable: The MMS1012G
is ETL Listed to the stringent
requirements of UL/cUL 458
and CSA C22.2 #107.1-01 for
mobile use.
Buy with ease: The MMS1012G is
backed by a two-year (24-month)
parts and labor warranty.

The MMS1012G is a pure sine wave inverter-charger that provides a cost effective solution for those with smaller power needs in mobile applications and is ideal for emergency vehicle applications.
This new model comes with a flexible cord on the AC input and a GFCI outlet on the output for easy connection to your AC appliances; ready to use after connecting to your batteries.
The MMS1012G is designed to accommodate entertainment systems and small appliances in smaller RVs, boats and vehicles in an all new design. Based on the popular ME and MS Series inverters, the MMS is smaller, lighter and less expensive while retaining all the built in protection and reliability of ME and MS models.
The MMS uses a PFC (Power Factor Corrected) charger, which is 85% efficient and the same charger topology used in all Magnum models.
