Intelligent Battery Charger

The NPB and NPP series are MEAN WELL s new generation of high-power'
density smart chargers. The NPB-120/240/360 series adopt a high
efficiency hardware design, allowing the products to operate both
efficiently and stably. The NPB-450/450NFC/750/1200/1700 series are
fully digital designed products and feature the benefits of
miniaturization, high efficiency and intelligence. Being a high efficiency
hardware and microprocessor power management design, with four
charge curve selection (one programmable and three embedded) and the
world's first invention: auto ranging charge, the chargers have the ability
to cope with various batteries from different brands, such as lead-acid
batteries (flooded, gel and AGM) and li-ion (lithium iron, lithium
manganese), which some may require special charge treatment. Users
also can adjust and modify charge parameters (charge voltage/current,
cut-off voltage/current...etc.) in each charge stage via the built-in CAN
bus interface, some battery protection functions, in addition, may be
disabled through the intelligent communication interface. The whole NPP
family is equipped with both charger and power supply modes. These two
modes can be set freely according to user s demand. In the charger mode,'
a three-stage charging function is provided, and the charging voltage and
current can be adjusted according to different batteries. If it s in the'
power supply mode, it will be able to driver loads. The flexible andgeneral
intelligent design of the NPB and NPP series can provide a perfect
solution for complex battery applications.

nIt is suitable for lead-acid batteries (flooded water type, el colloid type,g
AGM adsorption glass fiber) or (lithium iron, lithium manganese, lithium
ternary…etc.)
nThe charger must be installed in a dry and well ventilated area. It should
not be exposed to rain or snow.
nAll failures should be examed by the qualified technician.
nThe cables between charger and battery should be kept as short as
possible to prevent excessive voltage drop (suggested cable length:
50cm~100cm). Too much voltage drop will lead to longer charging period.
nMake sure charging voltage and current meet battery's specification.
nRefrain from connecting new and old batteries in series.
nCharger should be in the OFF mode before making battery connection or
disconnection.
nFor auto ranging. Please refer to the manual before using this function.
And note that, it must work together with battery that built-in BMS.
nThis equipment is not suitable for use in locations where children are likely
to be present.
nThe protective earthing is used as a safeguard, the instructions shall
require connection of the equipment protective earthing conductor to the
installation protective earthing conductor (for example, by means of a
power cord connected to a socket-outlet with earthing connection).

Note : For instruction of EN60335-1/2-29
nThis product is a built-in battery charger and is planned to be installed in caravans
and other similar vehicles. This product can charge at least one cell rechargeable
lead-acid or lithium-ion battery or one battery pack. When charging more
rechargeable lead-acid or lithium-ion batteries or battery packs, please refer to
the recommended capacity in this manual. It is recommended that the capacity
does not exceed the maximum battery capacity recommended in this manual. Do
not charge non-rechargeable batteries.
nThe battery terminal not connected to the chassis has to be connected first. The
other connection is to be made to the chassis, remote from the battery and fuel
line. The battery charger is then to be connected to the supply mains.
nAfter charging, disconnect the battery charger from the supply mains. Then
remove the chassis connection and then the battery connection.
nThe connection to the supply mains is to be in accordance with the national
wiring.
nThe appliance is not to be used by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge,
unless they have been given supervision or instruction.
nChildren being supervised not to play with the appliance.
nConnection of the appliance to the supply mains and the interconnection of any
separate components.
nNecessity to allow disconnection of the appliance from the supply after
installation.

Please turn off the charger first.
Select proper cable for connection between battery and charger
by referring to section 3.3
Connect the positive polarity of battery to the positive of charger,
and connect the negative polarity of battery to the negative of
charger.
Turn the power switch to“ON”position. If LED show in GREEN, it
states that the unit is in either charging or normal operation.

Wire connections should be as short as possible and less than
1 meter is highly recommended. Make sure that suitable wires
are chosen based on safety requirement and rating of current.
Small cross section will result in lower efficiency, less output
power and the wires may also become overheated and cause
danger. For selection, please refer to table 3-1.
