Power Supply

PSU power de-rating and option table , including ambient temperature details are here. The power details are

for input power.

• AC high voltage range input - 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).

• 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) Nominal voltage = 100Vac – 127Vac

• Input High Line (HL) Nominal voltage = 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.
