C3K-PWR-1150WAC Cisco 1150W AC Power Supply

C3K-PWR-1150WAC is a modular 1150 W AC power supply for the two supply bays of the Cisco Redundant Power System 2300 (RPS 2300). The same module is used in Cisco Catalyst 3750-E and 3560-E Series switches, and the RPS 2300 also accepts the 750 W C3K-PWR-750WAC. When two modules are installed in an RPS 2300 they must be of the same type.

Maximum output is 1150 W from a 115-240 VAC, 50-60 Hz input drawing 12 to 6 A. Output ratings are 12 V at 25 A and -52 V at 16.4 A, with a minimum output holdup time of 20 ms. The input receptacle is IEC 320-C13 (IEC60320-C13) with a 15 A power cord rating, and the front carries AC OK and PS OK indicators for input and output status.

Inside an RPS 2300, one C3K-PWR-1150WAC delivers 252 W (21 A) at 12 V DC and 800 W (15.4 A) at -52 V DC. Two modules deliver 540 W (45 A) at 12 V DC and 1600 W (30.8 A) at -52 V DC. With two 1150 W modules the RPS 2300 can fully back up two 48-port switches that deliver 15.4 W of PoE on all ports, and the modules can be hot-inserted.

The module measures 1.65 x 6.0 x 14.90 in. (4.2 x 15.24 x 37.85 cm) and weighs 5.6 lb (2.6 kg), longer and heavier than the 750 W module at 11.4 in. deep and 3.9 lb. Calculated MTBF is greater than 300,000 hours (Telcordia SR-332, Method 1, Case 3), with a demonstrated MTBF of 500,000 hours at 90% confidence.
