The Essential Series EcoPulse EC-10M is a civilian solar charge controller that specializes in ease of use and features necessary for battery charging. A lineup of 3 models that can be selected according to the solar system EC-10M, EC-20M, and EC-30M. All models are equipped with meter display and load terminals. Load terminals can be discharged controlled (battery low voltage load disconnected, reconnected). You can also switch between modes to connect and control the light fixture. ■ PWM 4-stage charging for full battery charge. Extends battery life by reducing overheating and excessive gas emission ■ DIP switch allows you to set the charge voltage and control mode of the load terminal. System voltage setting 12V/24V 7 ways of charging voltage and discharge control voltage (battery low voltage load disconnection, reconnect voltage). Switches from general load to lighting fixture control mode (Only turn on "sunset" and turn off "sunrise" on the "sunrise") The meter display can be used to monitor and custom settings, and operation. (Monitor) Battery Voltage Battery Charging Current Max, lowest battery voltage Battery level Battery Temp. Charging Stage Load working current. Battery charge amp hour for the day Load usage amp hour Time for each charging stage of the day. Failure (fault) and warning status. System operational status, etc. (Custom settings) Set charging voltage and time for each stage. Battery low voltage load shut-off and set reconnect voltage values (Operation) Manual start of equalization charging. Solar, load isolation Lighting Testing Controller reset etc. ■ Complete Protection Circuit Solar: Short Circuit High Voltage Polarity Reverse Connection Body high temperature and current reduction Night battery reverse current Load: Short Circuit Overload Main unit blocks high temperature loads. Battery: polarity reverse connection Lightning surge protection; Supports telecom mode hair with reduced noise. Due to the effect of PWM charging method, the device in the system may experience noise or radio failure, it reduces frequency switching speed and reduces noise. ■ Charging status, failure (fault), warning, etc. can be displayed on the LED display lamp. ■ Polycarbonate resin case with excellent impact resistance and weather resistance. Salt damage resistant terminals
