SL1524  SL1524LD LED Street Light Controller (Waterproof)

 

SL1524LD Function:

1.  Epoxy resin sealing processing, which increased its natureof being anti-thrown, shock-resistant, waterproof, damp proof, anti-corrosive, waterproof and achieve IP68 level.

1.System voltage is 12/24V automatically identification.

2.Anti-reverse protection ,Intelligent open circuit protection ,short circuit protection of LED driver

4.  SL1524LD built in high-precision step-up LED driver which can drive Max output voltage 55V, Max output power    120W for 24V System. Max driving efficiency is 95%.

5.Four time interval for PWM light adjustment, which makes LED Street light more intelligent and saves much electricity.

6.With temperature probe outside, temperature compensation is more accurate.

7.More advanced charging and discharging controlling calculation, which increases using efficiency of solar panel and extends battery longevity.

8. High power density, all is aluminum shell, volume is smaller but better performance.

9.SL1524LD has infrared wireless receiving and sending function, which can achieve wireless programming to controller by the SL02.

10. Consumers can adjust LED driver current with SL02 programming device, and no need to make specially.  

Note:  Remote is optional part to customer. If users want to change default parameters. Please buy remote or let us know detailed demand before factory production.

Status indication

 

Indicator		Status	Function
	PV Indicator	On	Solar panel has voltage and it is charging battery.
		Off	Solar panel voltage is low or 0 voltage or reverse connection.
		Blinking slowly	Battery is floating charging
	Battery indicator	On	Battery works normally.
		Off	Battery disconnected or battery reversely connected.
		Blinking slowly	Battery is under- voltage.
		Blinking fast	Controller is over-voltage.
	LED driver indicator	On	Load is working normally.
		Off	Load is off
		Blinking slowly	Load is open circuit.

 

 

Announcement

 

1.SL1524D is used for solar panel which is maximum output voltage is 50V ,battery maximum voltage is 35V.The load will be off when its voltage on battery is over 16.5V “(24V x 2)

 

2.SL1524LD built in big power and step-up LED driver, please be sure that LED module number, when LED connects in series, LED number range should be 5~15pcs for 12V system, and maximum power is 60W.  When LED module is in series and its numbers are in 10~15pcs, maximum power is 120W. The more LED module connects in series, the less bright they are.  If LED numbers are too less, which will cause LED lamp damaged and not constant.

 

 

3.SL1524LD driver default is 1.5A, please setup LED driver current which you need before connection. Otherwise,

If current is too big, it will damage LED module

LED current is determined by LED connection (in series and in parallel). For example: lamp cap is made up of 30pcs 1W Led, if it is for 12V system, Led number in series should be within 5~15pcs. The LED number in series will choose even number in order to make lamp cap look symmetrical and here are two connection ways

 

a)        Distributing into three units: connects 10pcs LED in series for each unit, then connect 3 units in parallel. Every units of LED current is 300Ma, total current of LED cap is 3*300mA=900 mA.

b)        Distributing into five units: connects 6pcs LED in series for each unit, then connects five units in parallel, LED current is 300Ma for each unit, total current of LED cap is 5*300mA=1500 mA.. We can see total current is different after different connection (in series or in parallel). We must confirm LED connection before installing lamp cap, and set up driver rated current through programming device, then connects LED cap.
