  The CXN series is a sophisticated solar charge regulator family with negative grounding. Beside a perfect PWM regulation with integrated temperature compensation, the controllers provide extraordinary display, programming and safety functions.
The battery state of charge is clearly displayed with a bar chart. The deep discharge protection function can be set up to five different modes: voltage controlled, SOC controlled or adaptive SOC controlled.
Acoustic warnings are built in, also a programmable nightlight function.
As an accessory we can provide an Excess Energy Management output to control special Phocos appliances like the DCL DC voltage converter.
The compact case design is prepared for DIN rail mounting (mounting device available as an accessory).
