  microcontroller improves performance and reduces costs by 12.5%
 Dulas has successfully adopted microcontroller technology to improve its solar
 powered vaccine refrigerator. The new product controller has improved performance,
 enhanced features and lower calibration and test costs. The use of the technology in
 Dulas’s solar powered products will enable the company to enhance its
 competitiveness and expand its market opportunities. The annual sales revenue
 resulting from the use of microcontroller technology is expected to double within
 4 years.

SIGNIFICANT ECONOMIC BENEFITS

                                           Sales of Dulas’s vaccine refrigerator and other solar powered products were
                                           expected to decline as a result of improved products from its competitors. The

PRODUCT IMPROVEMENTS

  The existing photo voltaic controller of Dulas’s VC150 solar powered vaccine refri-
  gerator was based entirely on discrete analogue components. It suffered from
  limitations related to the effectiveness of the battery fast charging process, and
  the level of user control and feedback. The improved microcontroller-based product
  has overcome these limitations and provided major feature enhancements including:
  • Improved battery charging system with monitoring and maintenance battery state.
  • Better protection to deal with reversed or open circuit battery connections.
  • User set up procedures and field adjustment facilities.
  • Display of battery voltage, charge and discharge currents.
  • System performance monitoring, recording and data transfer via serial port.
