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
