PWM AC/DC Hybrid Controller EH120

PWM Waterproof AC/DC Hybrid Solar Charge Controller With LED Driver

Intelligent Wireless Dimming-Type Controller for Commercial-Power Complementation

AC/DC Hybrid LED Solar Street Lights

Description

1. Wireless remote control: allow for parameters setting and status checking.
 
2. High precision digital constant current control: the maximum efficiency is up to 96%.
 
3. 12V and 24V lead-acid batteries and lithium batteries are available.
 
4. Features a DC detection function. If DC is available, the system will automatically switch to DC power supply when the battery voltage falls to the DC switching point; if DC power supply powers off, the system will shut off output when reaching the over-discharge point after continuous discharge.
 
5. The working current range is from 0.15A to 3.96A and can be accurate to 30 mA.
 
6. Power and working hours setting.
 
7. Intelligent power mode: The load power can automatically adjust according to the battery level.
 
8. All-sided monitoring for system; system status recording for 7 days at most.
 
9. Adopts a bidirectional handshake protocol and a data compression algorithm, realizing precise and fast data transmission.
 
10. Constant current control ensures smooth and stable current output, effectively preventing LED light from damage and extending the lifespan of LED.
 
11. With metal outer shell and IP68 waterproof rating, the product can function well in various tough situations.
 
12. Adopts an upgraded charging algorithm to reduce the vulcanization effect caused by battery over-discharge, significantly extending the lifespan of battery.
 
13. Battery charge and discharge temperature protection: when the temperature exceeds a certain value, the load will be shut off.
 
14. Provide battery/PV reverse electrode protection, LED short-circuit, open-circuit, and limited power protection, etc.
