DD760 Modular Charger System |
|
| |
Modular switched mode rectifier system |
|
| |
 |
|
| |
The DD760 system is a convection cooled modular power system. The system can provide N+1 redundancy with its hot-swappable chargers and can be configured with integrated distribution panels and a battery monitoring unit providing automatic battery discharge testing. |

|
| |
- Convection Cooled
- Active current share
- Power Factor Corrected Input
- Hot-Swap module replacement
- Automatic Battery Discharge Testing
- Battery Temperature Compensation
- Up to 4 modules per system
