CIS-N — PWM charge controller with lighting control 10–20 A
Country: Germany · Model: CIS-N
An industrial 10 or 20 A PWM controller in an IP68 aluminium enclosure for solar lighting and off-grid 12 or 24 V systems working in harsh conditions. UL1741 and Class I Div. 2 certification opens up use at industrial and oil and gas facilities with hazardous areas of the corresponding class.

Description
Charging follows a 4-stage PWM algorithm, and the parameters are set through an infrared port without opening the sealed enclosure. The controller detects the 12 or 24 V system voltage by itself. The PV input is rated 30 or 50 V, so modules are matched to the battery rating. The IP68 aluminium enclosure tolerates dust, rain and snow, so it is placed right on the lamp pole or in a field cabinet. Besides UL1741, the controller complies with the Canadian standard CSA C22.2 No. 107.1-16, which matters for projects with North American requirements. The load output controls the luminaire according to a lighting program.
How to choose
The 10 or 20 A rating is chosen by the current of the solar array and of the lamp load. For larger arrays or longer cables, the MPPT version CIS-N-MPPT (15–30 A) with the same IP68 class and built-in dimming is suitable. If the controller is in a dry room, the CXNup with a display (10–40 A) is enough, and for a 48 V bank a CX-N-MPPT is needed.

FAQ
Can the CIS-N be used in hazardous areas?
The controller is certified to Class I Div. 2. This classification is North American, so the designer checks whether a specific zone is covered under the standards in force in Ukraine.
How is the CIS-N controller programmed without opening the enclosure?
Settings are sent through an infrared port from a separate programmer, so the IP68 sealing of the enclosure is not broken.
What solar module voltage does the CIS-N support?
Up to 30 or 50 V at the PV input; a 12 or 24 V battery is detected automatically.
What charging algorithm does the CIS-N use?
A 4-stage PWM charge in which the current gradually decreases as the battery approaches a full charge.
How does the CIS-N differ from the CIS-N-MPPT?
The CIS-N works on PWM, has a current of 10 or 20 A and a PV input up to 50 V. The CIS-N-MPPT tracks the maximum power point, accepts up to 95 V and an array up to 1350 W.
