The Allen-Bradley 1756-PB72K is a standard DC power supply from Rockwell's ControlLogix 1756 range. It is the K (harsh-environment) version of the 1756-PB72 with the same ratings. It takes 18…32 V DC (24 V DC nominal) and delivers up to 75 W at 0…60 °C (32…140 °F) to the backplane: 10 A at 5.1 V DC, 4 A at 3.3 V DC, 1.5 A at 1.2 V DC and 2.8 A at 24 V DC. It measures 14.0 x 11.2 x 14.5 cm (H x W x D) and weighs about 0.95 kg. It mounts on the left side of a 1756 ControlLogix chassis (1756-A4, 1756-A7, 1756-A10, 1756-A13 or 1756-A17).
