LYNCOM MODEL N25T
PV SYSTEM LIGHTING
C O N T R O L L E R
Ly n c o m ’s micro p rocessor 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 contro l l e r s .
Model N25T is an advanced PV lighting system
c o n t roller 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
re c reation facilities and marinas.
Field proven PWM design for battery charg i n g ,
reduces water loss, extends battery life, and allows
m o re daily amp-hours into the battery as compare d
to traditional “on-off” controllers. Model N25T
f e a t u res 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
c i rcuit (LVD) prevents battery over- d i s c h a rge during extended overcast periods. Model N25T
f e a t u res four system status LED’s and a red reverse polarity LED for PV or battery.
