Calculating Input Power Requirements for IC693PWR328 The following graph is a typical 48 VDC power supply efficiency curve. A basic procedure for determining efficiency of the 48 VDC power supply follows the figure.Input Power/Current Calculation for IC693PWR328 Power Supply Ŷ Determine total output load from typical specifications listed for individual modules in Chapter 2. Ŷ Use the graph to determine average input power. Ŷ Divide the input power by the operating source voltage to determine the input current requirements. Ŷ Use the lowest input voltage to determine the maximum input current. Ŷ Allow for start-up surge current requirements. Ŷ Allow margins (0% to 20%) for variations.IC693PWR331 High Capacity Power Supply, 24 VDC Input The Series 90-30 DC input High Capacity power supply (IC693PWR33) is a 30 watt wide range supply designed for 24 VDC nominal inputs. For applications requiring greater +5V current capacity than is available with the standard supply, this supply allows all 30 watts to be consumed from the +5 V output. It will accept an input voltage range from 2 VDC to 30 VDC. Although it is capable of maintaining all outputs within specifications with input voltages as low as 2 VDC, it will not start with initial input voltages of less than 8 VDC. This power supply provides the following outputs: Ŷ +5 VDC output. Ŷ +24 VDC Relay power output which provides power to circuits on Series 90-30 Output Relay modules. Ŷ Isolated +24 VDC, which is used internally by some modules, can also be used to provide external power for 24 VDC Input modules. The load capacity for each output of this power supply is shown in the following table.
