(Example) Parallel OperationModel: NTDM-4HS-28-54

4 Each 1500 Watt modules in parallel providing a total of 6000 Watts.

(Example) Redundant Operation (N+1)

Model: NTDM-4HS-28-107 ORD: 4 Each 3000 Watt modules all units operating providing a total of 12,000 Watts. Should one fail the other units continue to provide the load of 9000 Watts.

OPTION DESIGNATIONS
SUFFIX CODE
Low Battery Voltage Disconnect (LVBD): The LVBD Module adds a new dimension to battery backup power supplies. The power supply simultaneously charges the battery and powers the load. If input power fails, the battery continues to support the load. However, when the battery voltage drops below a predetermined level, the LVBD module disconnects the battery from the load, thereby protecting the battery from the damaging effects of complete discharge.
