About the 3090-SRK-2

3090-SRK-2 is a PowerLogic 2 Slot Rack with an Integral Power Supply that is manufactured by Square D. Two non-addressable mounting slots for SY/MAX modules, which do not require backplane communications, are supported on this rack. This rack is designed with rear mounting brackets so that it may be mounted on a panel surface. Tie the rack assembly to ground with the grounding terminal that is located on the bottom left mounting bracket. Incoming power is wired directly to the control power terminals on the power supply cover. Above the control power terminals there is a 3 amp, time-delay fuse that provides electrical short protection. The total current draw on the rack by the connected modules must not exceed 7 amps.

The AC input voltage range is 85-264 VAC at 50-60 Hz. the DC nominal input voltage is 125 VDC. The AC burden is 120 VA and the DC burden is 1.0 amp. The powerloss ride-through at the full rated load is 15 ms. The nominal output voltage is 5 volts, and the output current capacity at 60° C is 7 amps. The input fuse type is a 3 AG slow-blow. The input fuse rating is 3 amps. This rack must be mounted in order to allow for adequate ventilation and heat dissipation. Use three 10-24 UNC mounting screws to mount the rack. Cover unused rack slots to prevent conductive particles from entering the open slot. Keep all AC power wires isolated from communication cables in order to minimize coupling of electrical noise.
