NHC3000 AC-DC Series Data Sheet Features • Single-phase AC input • 3U height • Active current share • Power Factor Correction (PFC) Meets EN61000-3-2 • Remote voltage adjust, and current monitoring • Overtemperature, overload, and overvoltage protection • Power supply status indicators • Output current meter (bar graph) • MTBF> 700,000 hours 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.

Output low threshold measured at output studs. Form C contacts, rating is 500 mA at 30 VDC. Relay closes >5 ms before output drops to <95%. Relay opens after output is in regulation. Form C contacts, pull-up to +5 V through a 1 k⍀ resistor. Signal provides an output of 0-10V which applies over 10-100% of rated load. At 50% load: Applies over 10-100% load as a percentage of full load. Total voltage compensation for cable losses with respect to the main output. Referenced to negative output terminal and derived from the internal 5.1 VDC. Margin High - Connect Margin input to Margin Ref. Margin Low - Connect Margin input to Logic Common. PF drops to “0” before output drops to 95% due to loss of AC. PF goes to “1” (logic high) after +5 V is in regulation. Form C Warning Time: contacts pull up to +5 V through a 1 k⍀ resistor.
