Cisco NCS 1004 Hardware Installation Manual page 40

Power Supply
• AC low voltage range input - 1300 W upto 40-degree C for 1 PSU; 1300 W upto 55-degree C for 2 PSUs
(for a short duration, as specified by Telcordia GR-63-Core).
• DC power supply - 2100 W upto 40-degree C for 1 PSU; 2100 W upto 55-degree C for 2 PSUs (for a
short duration, as specified by Telcordia GR-63-Core).
Caution
The NCS 1004 chassis needs to have both the PSUs at all times. In case, one of the PSUs is not energized
(due to a fault or missing mains), ensure that the system works at an ambient temperature of not more than
40 C.
For DC-DC (2000W @12Vout)
• Input Voltage Rating = -48Vdc / -60Vdc
• Max. Input current @48Vdc = 44A
• Input Voltage range = 40.5 Vdc – 72 Vdc (operating)
• Input turn ON Voltage = -42 Vdc max
• Recommended FUSE rating = 60A max. per feed
For the AC-DC (2000W (HL) / 1300W (LL) @12Vout)
• Input Low Line (LL) voltage range = 100Vac – 127Vac
• Input High Line (HL) voltage range = 200Vac – 240Vac
• Max Input current @100Vac = 15A
• Max Input current @200Vac = 12A
• Input frequency rating = 50/ 60 Hz
• Input LL voltage range = 90Vac - 140 Vac
• Input HL voltage range = 180Vac - 264 Vac
• Input frequency range = 47Hz – 63Hz (nominal 50/60Hz)
• Input turn ON voltage = 80Vac / 175 Vac (LL/ HL)
• Recommended FUSE (HL) = 16A
• Recommended FUSE (LL) = 20A
For the trip time response, the breaker trip curve may be "D" or faster.
