CMTB series solar street light controller designed specifically independent solar power generation system,
Mainly used in load needs light control, time control, light control and time combination of automatic control
switch system.
Such as: solar street lamp system,garden light system light control open nightly monitoring equipment.
Main Feature:
· Efficient tandem PWM charging, extend the life of the battery and improved system performance;
· Use power MOSFET as an electronic switch, without any mechanical switch;
· With accurate temperature compensation;
· Has broad applicability, automatic identification of day / night;
· With light control delay function, lights timed period from 1 to 15 hours adjustable;
· LED digital display of the menu settings and concise, easy to use;
· The controller has over-temperature, over charge, over discharge, overload, short-circuit automatic protection.
