LYNCOM N SERIES
PV SYSTEM CONTROLLERS
Lyncom’s microprocessor based charge controllers incorporate state-of-the-art design and
advanced pulse-width-modulation (PWM) battery charging operation, offering the highest
quality and more features of comparably priced PV
controllers. Field proven PWM design for battery
charging, reduces water loss, extends battery life, and
allows more daily amp-hours into the battery as
compared to traditional “on-off” controllers.
The ‘N’series controllers are advanced PV system charge
and load controllers for 12 or 24 volt solar systemsrated
up to 25 or 35 amps, intended for PV applications such
as remote homes, cabins, house-boats, campground &
recreation facilities, or telecom sites.
The‘N’series controllers display four system charging
status LED’s. The reverse polarity protection circuit
design features a reverse polarity – red LED for PV, or
battery, ensuring proper hook-up.
Models N25(M) and N35(M) are controllers featuring a
built-in LCD digital system monitor which accurately
displays battery voltage, push buttons display PV and load currents. A load management-low
voltage load disconnectcircuit(LVD)isstandard onallmodels, andpreventsbattery over-discharge
during extendedovercast periods.
The ‘N’series controllers come equipped witha receptaclefor adapting a multitude of single
plug-in options: remote temperature sensing, remote LVD alarm signal, audible LVD alarm
beeper, remote LCD monitor, adjustableHVD and LVD voltage regulation, and remote control
of manual switch for the load.
