Phocos CXN20 Solar Charge Controller (12/24V)
Description
Phocos CXN20
PV solar charge controller
The Phocos 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 night- light function.
The compact case design is prepared for DIN rail mounting (mounting device available as an accessory).
- Built-in 1 Year Data Logger for System Analysis
- Choose between 5 load disconnect algorithms
- Temperature compensated 3 Stage (Boost/absorption/float) PWM Series Regulation
- Automatic 12/24 V detection
- Prepared for DIN rail mounting (CX-DR2.1)
- Optional external temperature sensor (CXNT)
- Optional remote display (CXM multi-meter)
- Optional USB interface (CXI + CXCOM).
