What’s normal voltage of Sinbosen FP/DSP series Power amplifier?

For FP amplifier / DSP amplifier, normal voltage is 110V Or 220V
Because their power is too big,it is difficult to add the change-over switch. You only can choose 110V or 220V version.
Our 110V amplifier Version, workable voltage range is 90-130Volts;
Our 220V amplifier Version, workable voltage range is 200-240Volts;

If you don’t know what’s the workable voltage on your market,you can contact our sales for help. We will give you professional guidance.
If the voltage in your country is 110V-220V, we recommend you to choose a 220V power amplifier.
 

But what happens if the amplifier voltage is wrong !?
 
Local Working Voltage      220V  110V
Your amplifier voltage     110V    220V
If you connect with wrong Voltage.What happen?   Your Amplifier will be burned at once.The power supply board may exploded. Take care!   Your Amplifier not burned but can’t be turned on.
 


How to change the amplifier voltage between 110V and 220V?

Attention! Before following operations, please make sure your amplifier is power off. To prevent electric shock, if you have turned on the amplifier, wait 15 minutes before re-operation.


--There are two main steps need to modify.
 
Step 1: Change the Fuse
(Different model under different voltage, the fuse quantity is different.)
Fuse position: See below Image 001
 
 
    Remark:      Amplifier Model             Fuses            
110V    FP10000Q and FP6000Q    2 fuses
FP20000Q、FP22000Q、FP14000、FP9000、FP7000  3 fuses
220V  FP10000Q and FP6000Q   1 fuses
       FP20000Q、FP22000Q、FP14000、FP9000、FP7000          2 fuses
 
step 2: Refer to the figure below to find the corresponding ABCD point position on the power board.
 
- A-B、C-D connected, Power Amplifier voltage is 110V-115V
- B-C connected ,Power Amplifier voltage is 220V-230V

Position: See below Image 002
 
 

First, if you want to change the amplifier voltage from 220V to 110V 

Step 1: Add another 30A fuse. 
Step 2: Please connect points A and B, points C and D.

See below Image 003 and Image 004.
 


Second, if you want to change the amplifier voltage from 110V to 220V

Step 1: Take the next 30A fuse.
Step 2: Please connect points B and C.

See below Image 005 and Image 006.
