Description
The NHC3000 Series of chassis-mounted power systems provides AC front-end capability to telecom, data
communications and other distributed power designs. The NHC3000 can also be used for many other applications
requiring bulk power.
NHC3000 power supplies provide excellent protection against input voltage transients. A connector at the rear of the
supply provides access to interfaces for remote sensing, remote voltage adjust, current sharing, power supply status,
standby logic voltage, remote on/off, and power connections.
Airflow for the NHC3000 is from the front through the rear. The output is floating with respect to the chassis and may
be used as a positive or negative polarity supply.
