DD696 19" Rackmount Charger |
|
| |
Modular switched mode rectifier |
|
| |
 |
|
| |
The DD696 is a 2U rack mount power supply. With the optional battery disconnect module the unit provides a complete battery backup solution. Two or more units can be connected in parallel with an active current share feature to provide greater output power or redundant (N+1) operation. |
