Product details:
 




Product features:
1) Output voltage and output current and charge state display
2) High precision and regulated voltage, the regulated voltage precision coefficient less than 0.1%
3) Over voltage protection automatically, if output voltage is higher than normal output voltage range, it will cut off the power automatically so as to ensure the safe of the station.
4) Over current protection automatically, if output current is higher than Max. Current or short circuit, it will cut off the power automatically.
5) Pulse current charging with fast and float charging and switch automatically.
6) Wide voltage range
4) If there has mains power, the power supply will charge for the battery, if there has no mains power, the battery will supply to the power supply automatically. ( Battery backup function)
 
Product usage
Special for communication station, especially suitable for police office, water conservancy, communication department and all kinds of mine factories.
 
After sell service:
1.1 years warranty,by replace/repair/free spare parts for bulk order.
