WS-AL2430 30A WELLSEE Street Lamp Controller

 

PWM controller

 

 

WS-AL2430 30A WELLSEE solar street lamp controller, can intelligently senses the strength of the light outside. It can automatically open the lamp at dark, and turn to high-light automatically after giving the lamp low-light for half an hour. And then turn to morning light when set time is up or at day break. After that, the lamp can be closed automatically after half an hour (the time of high-light can be set.) The time of the high-light can be set as you request. Ten hours high-light can be set as full power plus half power light. For example, 4 hours full power light(full light of the bulb) and then 6 hours half power(half light of the bulb), after that  morning light until day break, then the controller will turn off the load automatically.  This controller can adjust the light accordingly to save the energy.

WS-AL2430 30A WELLSEE solar street lamp controller adopts PWM dimmer technology to adjust the light of LED lamps, can work with different kinds of constant-current source. This controller has the advanced characteristics of low cost, simple maintain, simple connection, easy maintenance, energy saving, reducing surge current and high power factor. Compared with the ordinary lamp controller, this AL controller can save more than 35% energy.

WS-AL2430 30A WELLSEE solar street lamp controller adopts the most advanced devices. LED display clearly shows the working of the system. And this controller can work in cold, high-temperature, hot environment and other harsh environment. Different from other ordinary controller, this dimmer controller has the protection function, which can make the Solar PV System working efficiently and safely.

Functions:

1.    12V/24V automatically detection

2.    intelligently senses the light outside, turn on automatically when getting dark and turn off when day break

3.    Micro-processing controller pulse-width modulation (PWM) charging

4.    Light intensity can be set to save energy consumption, thereby achieving the energy saving effect

5.    It can prevent reverse charging (the battery charges the solar panel).

6.    Lightning protection, short circuit protection (with self-recovery)

7.    It can prevent anti-charging function (solar panels to charge batteries)

8.  It can prevent reverse connection of the battery and solar panel.

9.    It can set 20 time grade or 10 minutes section modes

10.It has a LET indicator of the working condition of charging and discharging:

²  One piece of Charge Indicator LED (mark: Charge). When it is bright, the battery is charged strongly; flickeringly means floating charge, no light means stop charging.

²  One piece of Load Indicator LED (mark: Light). When it is bright, there is output and load can work; if LED goes out, means there isnt output and the load cannot work.

²   Battery indicator:  red under =voltage   Green =full    Yellow =normal
