Wellsee WS-SC2460 three -stage solar charge and discharge controller
Brand: WELLSEE Dimension: 183*120*68 mm Name : three stage solar charge and discharge controller Weight: 960g model: WS-SC2460 Package: 18pcs/ctn
Wellsee company is one of leading manufacturer and global supplier of wellsee solar controller and photovoltaic equipments. Wellsee products have passed ISO9001, CE and RoHS certificates, and can be designed and produced according to the customer’s requirement. Welcome to be our agent!WS-SC2460 wellsee three-stage solar controller (also called wellsee photovoltaic controller /solar charge and discharge controller ), applies in solar photovoltaic system which coordinates the working of solar panels, batteries and loads. This controller is different from other solar controllers which has advanced three -stage charging function that can make battery fully charge battery and also increase the comprehensive protective functions so that the entire system can operate efficiently and safely.Wellsee three -stage solar controller is totally different from othercontrollers with three stage charging mode:it charges by battery charging characteristic curve and adopts to intelligent three steps charging mode “constant current- constant voltage and limited current-Purling floating”,It make the battery full of power and it has advanced human-machine interactive function that user can adjust charging voltage.Three-stage charging mode (take 12V system as an example.)1.Constant current fully charge stage: directly charging battery by using constant current output characteristic until the voltage of battery is up to 13.7V(can be set)2. Constant voltage charge stage: controlled by PWM, the battery voltage is kept at 13.7V, till charge current is less than Purling current floating charge voltage;3. Purling current floating charge stage: continue to control by PWM and keep the charge current keep in floating status until battery voltage is up to 14.2V, charging is over.If the started voltage of battery is higher than the lowest protection voltage, the system will go to the Purling current floating charge stage automatically to prevent frequent overcharging; if started charge voltage is lower than the lowest protection voltage, the system will go to three-stage charge mode.Three-stage charge mode uses constant current charging at the beginning and the end, and uses constant voltage charging in the intermediate stage. When the current is decayed to the set value, it switches from the second stage to the third stage. This mode can make the outlet minimum to protect the battery better and really charge the battery fully.WS--SC2460 Wellsee three-Stage charge controller applies to all types of solar panel and lead-acid batteries(other types of batteries can be set charging curve according to customer’s requirement), MCU (Micro processing controller) has PWM (Pulse Width Modulation) program. It can provide fast and best charging voltage and current from the PV panel according to different types of batteries and power supply of panels .Functions:Intelligent three stage charging mode: constant current charge→ constant voltage and limited current charge→ purling current floating charge .1.CPU control, LCD display2.Automatic recognition of input voltage • Applicable to various types of durable batteries3.Micro processing controller Pulse Modulation Wide-frequency (PWM) charge4.low voltage cut-off can be set /resuming connection of the DC output of the load port5.Temperature sensor for charging a battery in compensation6.Protective circuit of PV from reverse-charging.7.Overload protection8.Overcharge protection9.Short circuit protection10.reverse discharge protection11.Reverse polarity connection protection12.Thunder protection13.Low voltage protection14.LCD display parameters in turnTechnical Index:
