Product Description
1.Advanced IC and components can ensure reliability and stability
2.Charge battery strictly according to Charging Curve.
3.The charging process is “(preset) constant current→(reach to equal charge constant voltage value)constant voltage reduce current→(automatic switch)float charge”. With strongpoint such as fast speed, high efficiency, unattended, non over charge etc
4.The charging current of 48V 20A auto battery charger is about 1-20A Constant adjustable. When in constant current charging status, the current is constant. No need manual adjustment.
5.AC wide range of input
6.Intelligent temperature controlled fan and over temperature automatic shut off protection.
7.Output short circuit protection and polarity reverse protection.
8.Suitable for assistant start-up power supply and complementary charge power supply such as car or generator etc.
