CIS-N series is a new member of the CIS series. It was specifically developed to bring optimum performance and the useful features of the popular positive-grounded CIS charge controller to negative-grounded applications. Thanks
to its robustness and design, this charge controller is ideal for applications in demanding environments like the gas and oil industry, for traffic systems (e.g. traffic control systems, signal lamps), and for any PV applications which are exposed to harsh environmental conditions.
