BY APPLICATION

Solar & Wind

Renewable energy is clean, affordable, domestic, and effectively infinite. It produces no emissions and results in cleaner air and water for all. Wind energy is now one of the most cost-effective sources of new generation, competing with new installations of coal, gas and nuclear power. Most renewable energy comes either directly or indirectly from the sun. Solar energy can be used for generating electricity during the day and complements wind energy generated during the night.

Energy Management

Energy management is the proactive, organized and systematic coordination of procurement, conversion, distribution and use of energy to meet the requirements, taking into account environmental and economic objectives.
Battery energy management

Battery health management predict the end-of-discharge (EOD) event that indicates that the battery pack has run out of charge for any given flight of an electric UAV platform. The amount of usable charge of a battery for a given discharge profile is not only dependent on the starting state-of-charge (SOC), but also other factors like battery health and the discharge or load profile imposed.
Automation Devices

For better technology Automation devices are leading head, The Series of current sensors consists of both current switches and current transducers can be used to activate an external contactor. They can sense external currents with a Solid or Split current sensing ring.
