1. General Safety Instruction
1.1 Safety Instruction
As dangerous voltages and high temperature exist within the LMP1218-PWM Master Power Unit,
only qualified and authorized maintenance personnel are permitted to open and repair it. Please
make sure the unit is turned off before open and repair it.
This manual contains information concerning the installation and operation of LMP1218-PWM
Master Power Unit. All relevant parts of the manual should be read prior to commencing the
installation. Please follow the local stipulation meantime.
Any operation against safety requirement or against design, manufacture, safety standard, and are
out of the manufacturer warranty.
1.2 General Precaution
1) Do not expose to dust, rain, snow or liquids of any type，it is designed for indoor use. DO NOT
block off ventilation, otherwise the LMP1218-PWM Master Power Unit would be overheating.
2) To avoid fire and electric shock，make sure all cables selected with right gauge and being
connected well. Smaller diameter and broken cable are not allowed to use.
3) Please do not put any inflammable goods near to this unit.
4) Never place this unit directly above batteries, gases from a battery will corrode and damage
LMP1218-PWM Master Power Unit.
5) Do not place battery over LMP1218-PWM Master Power Unit.
1.3 Precaution regarding battery operation
1) Use plenty of fresh water to clean in case battery acid contacts skin, clothing, or eyes and consult
with doctor as soon as possible.
2) The battery may generate flammable gas during charging. NEVER smoke or allow a spark or
flame in vicinity of a battery.
3) Do not put the metal tool on the battery, spark and short circuit might lead to explosion.
4) REMOVE all personal metal items such as rings, bracelets, necklaces, and watches while
working with batteries. Batteries can cause short-circuit current high enough to make metal melt,
and could cause severe burns.

3. KEY FEATURES AND FUNCTIONS
3.1 Multiple inputs
LMP master power unit may have multiple sources at one time. These sources include the Shore
power, Solar panel and Alternator (Motor battery). There is priority among these sources, but LMP
allows several sources to charge auxiliary battery at the same time. The priorities are listed below.

3.2 Battery Charger of Auxiliary Battery
The charger automatically starts when the appropriate qualified power is connected, either from grid,
generator. With multiple charging stages (soft start-bulk absorption float-recycle), LMP1218-PWM is
designed to fully charge battery quickly. To guarantee the optimal charging for batteries of different
states, the LMP1218-PWM features Microprocessor-controlled charging algorithm. The Float and
Recycle charging programs guarantees the battery being charged properly upon being connected
for a longer period.

3.3 Lithium battery charging
The LMP1218-PWM can be configured to charge Lithium battery.
3.4 Power Supply Mode
If no battery is attached to LMP1218-PWM unit, it will work as a power supply automatically with a
12.8VDC output.
3.5 PWM Solar charger controller
LMP has a built-in PWM charger for the service battery.
Max open voltage is 30VDC
Max supply current is 15A
3.6 Voltage Charging Relay (VCR)
LMP1218-PWM Master Power Unit has a built-in voltage charging relay (VCR), which can get power
from alternator to supply the system whilst the engine is running.
Here is the working logic of VCR

Engage
VCR will be engaged
when:1) D+ is sensed or
detected; 2) Alternator or
motor battery’s voltage is
greater than 12.0V for 10S
VCR will be engaged when
alternator or motor battery’s
voltage is greater than
13.4V for 10S
Remarks:
a. D+ enabled means the LMP box has sensed or detected D+ once, afterwards LMP box
would deem it as D+ enabled
b. D+ disabled means the LMP box has never sensed or detected D+, so LMP box would
deem it as D+ disabled
