LYNCOM MODEL N25T
PV SYSTEM LIGHTING
CONTROLLER
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 than comparably priced
PV controllers.
Model N25T is an advanced PV lighting system
controller for 12 or 24 volt solar systems rated up to
25 amps, designed specifically for applications such
as billboards, street or park lights, campground and
recreation facilities and marinas.
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. Model N25T
features an automatic load timer, which senses
dusk by the solar array and initiates the lighting
time period, which is field adjustable.
The Model N25T lighting timer can be pre-set for
operation of 2, 4, 6, 8, 10 hours, or from dusk to dawn. A low battery voltage load disconnect
circuit (LVD) prevents battery over-discharge during extended overcast periods. Model N25T
features four system status LED’s and a red reverse polarity LED for PV or battery.
