14.1.Use of AC/DC Converter

In usual cases, 3P@C 4450E uses the DC -48V for power supply. In some application environments that the DC power supply is not available, however, AC220V is needed, so the AC/DC converter is the choice. At present, the AC/DC converter for choice is the HD4825 rectification module converter.

1. For the detailed description of HD4825, refer to HD4825 Rectification Module Use. Here, the connection of power supply for the

Hammmer10000 AC power supply is the main concern.

prompt 2. Other 4825 converters can also be used.

The procedure of power supply connection in the 3P@C 4450E AC power supply is as follows:

Step 1

 

For 3P@C 4450EV2.00,

 

 

 

Use the cable connector matched with HD4825, and connect the “+” pole

 

 

 

(red wire) for the HD4825 DC output with the BGND (black wire) for

 

 

 

3P@C 4450E DC power input wire connector; connect the “-” pole (black

 

 

 

wire) for HD4825 DC output with –48V (blue wire) for 3P@C 4450E0 DC

 

 

 

power input wire connector.

 

 

 

For 3P@C 4450EV1.00,

 

 

 

Use the cable connector matched with HD4825, and connect the “+”

 

 

 

pole (red wire) for the HD4825 DC output with the BGND (black wire)

 

prompt

 

for 3P@C 4450E DC power input wire connector; connect the “-” pole

 

 

 

(black wire) for HD4825 DC output with –48V (red wire) for 3P@C

 

 

 

4450E0 DC power input wire connector.

Step 2

 

Insert the 3P@C 4450E DC power input wire connector into the

 

 

 

corresponding connector of 3P@C 4450E backplane, and insert the

 

 

 

HD4825 connector into the DC output port at the back of HD4825. The

 

 

 

description of 3P@C 4450E backplane power connector ad the DC

 

 

 

output port at the back of HD4825 is shown in Figure 14-1.

Step 3

 

Connect the 220V AC power supply to HD4825, as shown in Figure 14-
