Street Light Controller Boost Driver

We are involved in manufacturing of Street Light Controller Boost Driver to our clients.
FEATURES
a c High efficiency at full load, efficiency 75% to 85% depending on load
a c Auto battery cut-off at full charge
a c Low battery auto cut-off at 10.5v to 11v to preserve longer battery life
a c PWM charging at a relatively constant efficiency regardless of the size of solar panel
a c Approx. 30ma Quiescent current
a c Unlike fixed selected output controller this one gives you the ability to tweak
Output current by changing pot for various Weather conditions
a c fixed output regardless of battery voltage variations
a c full battery auto cut-off at 14v battery level and hence preserving battery life by avoiding overcharging
a c Very low solar charging voltage drop 0.3v to 0.5v

INPUT/OUTPUT SPECIFICATION
a c Supply voltage dc 10.5v to 15v (for 12v battery applications)
a c Input solar voltage 20v solar panel up to 150w solar panel
a c Variable output watt 9w to 35w LED luminary
a c Solar charging voltage drop 0.3v to 0.5v
