1756-PC75

The 1756-PC75 ControlLogix Standard Power Supply Module by Allen-Bradley is a DC power supply module installed on the Left side of the 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17 chassis which has a nominal input voltage of 48V DC and a voltage range of 30-60V DC. It has a maximum input power rating of 95W, an output power of 75W, and an operational thermal dissipation of 68.2 BTU/hr. The 1756-PC75’s circuit has a nominal signal hold-up time of 50ms at 30 to 60V DC and a maximum inrush current of 20A. It has a load-dependent current carrying capacity of 1.5A at 1.2V, 13A at 5.1V, and 2.8A at 24V DC. The 1756-PC75 offers 15A max user-supplied over-current protection and it offers circuit protection to a circuit-soldered non-replaceable fuse. It has a circuit isolation voltage of 250V DC (continuous) with reinforced insulation tested at 3500V DC for 1 minute between power input-to-backplane. The 1756-PC75 has a T4 North America designated temperature code and comes in an open-style enclosure. It has a 0-60 °C operational temperature margin at 5-95% non-condensing humidity and its non-operational storage temperature limit is between -40 and 85 °C (-40 and 185 °F). In a non-operational mode, the 1756-PC75 can withstand a shock of up to 50G, and when operational, it can withstand a shock of 30G and a vibration of 2G at 10-500 Hertz. It has an approximate dimension of 140mm x 112mm x 145mm (5.51in x 4.41in x 5.71in) and weighs approximately 0.95 kg (2.10lb).
