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

1.2.1 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.

1.2.2 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.

1.2.3 Please do not put any inflammable goods near to this unit.

1.2.4 Never place this unit directly above batteries, gases from a battery will corrode and damage

LMP1218-PWM Master Power Unit.

1.2.5 Do not place battery over LMP1218-PWM Master Power Unit.

1.3 Precaution regarding battery operation

1.3.1. Use plenty of fresh water to clean in case battery acid contacts skin, clothing, or eyes and

consult with doctor as soon as possible.

1.3.2. The battery may generate flammable gas during charging. NEVER smoke or allow a spark

or flame in vicinity of a battery.

1.3.3. Do not put the metal tool on the battery, spark and short circuit might lead to explosion.

1.3.4. 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.

LMP1218-PWM Master Power Unit User Manual

IDM Technologie

The LMP1218-PWM can be configured to charge Lithium battery.

3.3 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.

3.4 PWM Solar charger controller

LMP has a built-in PWM charger for the service battery.

² Max open voltage is 25VDC

² Max supply current is 15A

3.5 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.

LEAD ACID BATTERY -- When the motor battery reaches 13.4VDC with threshold time delay, the

VCR will be engaged to allow power from alternator to supply the system. VCR will continue

being engaged until the motor battery’s voltage drops under 12.8VDC.

LiFePO4 LITHIUM BATTERY -- When the motor battery reaches 14.0VDC with threshold time

delay, the VCR will be engaged to allow power from alternator to supply the system. The VCR will

continue being engaged until the motor battery’s voltage drops under 13.5VDC.

The VCR will be disengaged when the auxiliary battery’s voltage reached 14.8V.

NOTE: If vehicle is fitted with a smart charging system (Variable Voltage or Temperature

Compensating), the VCR charge system may not function correctly and a DC-DC Charging

system is recommended

Please consult your local dealer or installer for further information.

3.6 Battery Low Voltage Protection (BLVP)

LMP1218-PWM master power unit has a built-in low voltage protection relay. It will disconnect

the load once the battery voltage drops below the threshold voltage. The default setting is

10.8VDC.

3.7 Manual Battery Switch

The LMP1218-PWM unit offers a convenient way to switch off the output of the auxiliary battery

on-board. It protects the auxiliary battery from being drained by electronics on board, completely

isolating the battery.
