SML series

Function

l  Battery State-of-Charge display with 3 LEDs

l  Acoustic load disconnect pre-warning

l  PWM-regulation (series type)

l  Boost, Equalize and Float charging, also for VRLA

l  Integrated temperature compensation

l  Large terminals (up to 24mm2 wire size)

l  SOC and voltage controlled LVD

l  Fully electronically protected

 

 

The SML series is a sophisticated solar charge controller family for low cost applications.

 

The electronic circuit is equipped with a microcontroller that provides high-efficiency charging technology together with a number of outstanding status display, warning and safety functions.

 

The temperature-compensated three-stage PWM charging method (boost-equalization-float) is now adjustable to sealed and vented lead-acid batteries. The new version also allows an either SOC or voltage controlled low voltage disconnect function.

 

The battery status is clearly indicated by three LEDs.

 

As the first controller on the market in this price range it comes with an acoustic low voltage load disconnect pre-warning feature.

SX series

Function

l  Battery State-of-Charge display LCD

l  Charge and discharge status display

l  Acoustic load disconnect pre-warning

l  Load status indication

l  Choose between 5 load disconnect algorithms

l  Boost/absorption/float PWM-regulation (series type)

l  Integrated temperature compensation

l  Covered terminals(up to 16mm2 wire size)

l  Full solid-state protection

 

 

The SX series is a sophisticated solar charge controller 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, also A programmable nightlight function.

 

 The compact case design is prepared for DIN rail mounting (mounting device available as an accessory).
