Phocos CX Series User Manual

The CX series is a sophisticated solar charge regulator family with exceptional features
in this price range. 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, as well as
energy flows from and to the battery and the load status (e.g. overload, load short
circuit). The deep discharge protection function can be set up to three different modes:
voltage controlled, SOC controlled or adaptive (fuzzy logic).
Acoustic warnings are built in, as well as a programmable nightlight function.
The CX also provides a built-in excess energy management function which means that
in combination with especially designed loads (e.g. Phocos Solar Refrigerators/Coolers
SF32E, SF50E) it is possible to make use of excess energy which would be lost
otherwise because of the overcharge protection of the battery. A better utilization of
the solar system is the benefit.
The compact case design is prepared for DIN rail mounting (mounting device available
as an accessory).
