PWM CONTROLLER EL--30A-40A-50A-60A-48V30A-48V40A

EL PWM SERIES - Solar Charge Controller Product Features

• 12V/ 24 V system voltages auto detection, EL-4830/4830 has for 48V. 

• Charging program options for sealed, GEL and flooded  lead-acid batteries and lithium batteries are available.

• PWM charging algorithm 3-stage is adopted. Application of an equalizing charge to the battery periodically or when over discharged, can effectively prevent the battery from non-equalization and sulfuration,thus extending the battery's service life (with the exception of GEL and lithium batteries).

• Temperature compensation employed, charging parameters can be automatically adjusted (with the exception of lithium batteries).

• Wide range of load working modes facilitate the product's application to different types of street lights and monitoring devices.

• Overcharge, over-discharge, overload protection, as well as short-circuit and reverse-connection protection.

• By virtue of an advanced load starting method, large-capacitance loads can be started smoothly.

• A range of parameter settings and power-down saving functions are available ,thus requiring no repeated setting.

• The product provides a dot matrix graphic LCD screen and a human-machine interface with 2 keys.

• Super friendly easy to use design of browser and dynamic interfaces ensure convenient and intuitive operations.

• Optional communication function - provides a RJ12 data port (output of TTL232 level or Bluetooth signals), with data adopting the standard Mod-bus protocol and can be used together with our upper computer monitoring software or mobile phone APP.

• Industrial grade design, the product can function well in various tough conditions.

• TVS lighting protection is adopted with good quality raw material manufactured for a long life span.
