What is different between battery charger and adjustable dc battery charger?
| Product name | Output voltage | Automatic identification battery voltage | Equal/float voltage | Digital display | Output current constant adjustable | Charging mode | Suitable for all kind of lead acid battery |
| Adjustable dc battery charger | Voltage adjust from 0v-max (v) | Yes | Be set before factory | Yes | Yes | Yes | Yes |
| Full auto battery charger | Can not adjust | No | Set by the end user | Yes | Yes | Yes | Yes |
What is the difference Between Switching power supply and DC adjustable power supply?
| Item Product |
Switching power supply | DC adjustable power supply |
| Output voltage | Generally The output voltage is 12VDC 24VDC 48VDC，Narrow range of Output voltage | Can customize any voltage. Such as:0~1000VDC. The output voltage range 0~100% continues adjustable |
| Output current | If less than 50A generally 10A 15A 20A 25A 30A 50A The output current is not adjustable. But the power with battery interface, the output current can be adjustable within narrow range of Output voltage |
Can customize any current. Such as 0~1000A.The output current range 0~100% continues adjustable |
| Application | Communication engine room | Battery charging,lab and etc. |
| Output interface | With battery interface (optional)+terminal output | Without battery interface ,only one terminal output |
| Equal charging & Float charging | Have equal charging and float charging, and can switch automatically | Don’t have equal charging and float charging, and Need manual adjustment. |
| Display | current and voltage just can switch display in one LED | Current and voltage display respectively |
| Machine parallel | Support multiple machines of same specifications parallel use | Can’t support parallel |
| Communication interface | RS485/232 optional | Without communication interface（If need communication interface,Can consult the factory of HuaYuan, the price is higher） |
| Input voltage range | Input AC range widely 176V～280V. But can’t make 110V/380V 3 phase input |
110/220/380+/-20% is the most wide input range |
| Appearance | Rack mount type | Desktop and Rack mount type can be customized |
| Working frequency | 160KHz | 50/60HZ |
