Description
The NNTDM-4HS Hot Swap Rack Mount Power Supply is typically a (N+1) design which ensures that full operation of critical loads continue should one module experience an interruption of service. This type of design makes them ideal for Telecom, Data Processing Transportation, Industrial, Military and Commercial applications where critical system operation is a must and no downtime can be tolerated. Hot Swap Systems provides the user the ability to remove and replace a module without compromising system functionality. The NNTDM-4HS Hot Swap Power Supply is available in a ruggedized “COTS” version for military applications. Custom configurations and other voltages and power levels are available.
