I)This controller's working voltage is DC 12V/24V adaptive, and maximum output current is 10A, with two way output. The constant current and power is adjustable by its efficient software, and the efficiency of the system achieve up to 96%. It's used for low-voltage control 12V/24V DC load. One of the features of this controller is flexible configuration parameters. Users can easily set the parameters of the controller and check the system's current operating parameters and status with software.

II) Features Overview
1. Using industrial MCU, constant current and power is adjustable by its advanced algorithms, especially suitable for solar LED street lighting system. As this controller achieves constant current without hardware circuit, so its efficiency gets 20% to 30% higher relative to using hardware circuit. And its maximum efficiency is up to 96%. So it not only decreases the cost of the system, but also improves the reliability of the system.
2. With its powerful configuration feature, users can control through the management software to complete the setting of various operating parameters, query the running status and load control, such as:
1) Set the light intensity when load is turned on;
2) Power-saving mode is configurable. It can independently set three stages of the output power for the main and auxiliary lamp, control the output curve in order to achieve energy saving.
3) Can check the working status and fault conditions of the current controller.
3. With complete protection:
1) Load short-circuit protection: once the load shorted, the controller automatically stops working to protect the solar panels, batteries, controller;
2) Reverse charge protection: To prevent the battery to reverse charging solar panels through the controller;
3) Reverse polarity protection: The ability to load, solar panels and battery reverse polarity protection, once the reverse, the controller stops working and normal starts after right connection;
4) Lightning protection: Can effectively protect the controller, solar panels and batteries not damaged by dodging lightning;
5) Charge and discharge protection: Charging protection means controller will choose different charge curves according to ambient temperature, to ensure the battery is full, and it will not overcharge. Discharge protection means when the battery voltage dropped to under-voltage protection voltage value (eg, 10.8V), main and auxiliary lamp turn off to avoid the battery damage because of over-discharge. User can set the under-voltage protection voltage value according to the discharge current, principle is the discharge current increases, the under-voltage protection voltage value can be set lower, whereas if the trickle discharge, under-voltage protection voltage value should be set higher.
