6.  The cells in the panel are made up of semiconductor
material which transforms light energy into electrical
energy.

7.  Diode D1 allows current into three regulator ICs to
provide regulated voltage to the load.
 High value capacitors C1 and C2 act as current buffers
so that a short duration interruption in current flow
from the panel will not affect the charging process.
 Red LED indicates the charging process.

12.  79xx devices which are complementary negative
voltage regulators.
 78xx ICs are easy to use and handle but these cannot
give a altering voltage.
 The input voltage must always be higher than the
output voltage by some minimum amount .

13. Applications
 This charger can replenish almost all types of batteries
including Mobile phone battery.

14. APPLICATIONS
 Security Cameras
 Remote Telemetry Units
 SCADA
 Monitoring
 Fence Charger
 Gate Opener
 Intelligent Traffic Systems
 General Battery Charging Applications.
 Charge laptop
 Any other 12V charge products, like digital camera,
electronic dictionary, etc

15. Applications
Charge laptop The
specification of battery
adaptor should between
10v to 14v.
