  • 48V 20A Full Automatic Battery Charger
  • Product Model : YK-CD4820
  • Product Information :

    AC/DC compatible input: AC220V AC±15%,50/60Hz;DC48V Charge current:1-20A adjustable Equal voltage: 58VDC Floating voltage: 54VDC Efficiency: ≥86%

  • Information

1.    Most of the traditional charger and simple charger are made up of industrial frequency transformer and rectifier circuit (silicon controlled rectifier (SCR)). Even use the silicon controlled rectifier to adjust the AC mains supply to charge battery. Though this circuit is simple, but it has disadvantage:

  1. Big volume and high weight, not convenient for transportation and use
  2. Lacking protection function, bad reliability
  3. Must manual adjust charge current, difficult to full charge and avoid over charge the battery.
  4. Silicon controlled rectifier adjusts the AC mains supply to charge battery directly. Then there is not isolation with AC mains supply which is dangerous to get an electric shock. And it will damage the AC mains supply waveform.

2.    Over discharge, over charge and longtime non full charge to battery will shorten the battery lifespan. So choose a good performance charger is very important.

3.    YK-CD Series full automatic battery charger uses the advanced non industrial frequency transformer switching power supply technology. It has small volume, low weight and high efficiency. Combining with the intelligent charge technology, it can prolong the lifespan of battery and full charge the battery. Over discharge protection, charging current adjustable, specially suitable for the unattended site.

4.    48V 20A auto battery charger can connect with the battery to keep full charge long time. Suitable for assistant start-up power supply and complementary charge power supply such as car or generator etc.

  • Character

A.    Advanced IC and components can ensure reliability and stability

B.    Charge battery strictly according to Charging Curve.

C.    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

D.   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.

E.    AC wide range of input

F.    Intelligent temperature controlled fan and over temperature automatic shut off protection.

G.   Output short circuit protection and polarity reverse protection.

Suitable for assistant start-up power supply and complementary charge power supply such as car or generator etc.

  • Customize Range

Regard as the auto battery charger , We can customize different specification are as following

1.  Charge voltage: 3.6660)V, customize

2.  Charge current: different current optional, customized, max 2000A

3.  Max power 100kw
