GE FANUC IC693PWR331 , High Capacity Power Supply , Series 90-30 Unit

Product Description

The GE Fanuc IC693PWR331 is a High Capacity power supply. This Series 90-30 unit runs off DC input. It has a 30 watt wide range and is designed for 24 VDC nominal inputs. If used in applications that demand more than +5V current capacity than provided by the standard supply, the IC693PWR331 power supply will allow all 30 watts to be consumed from its +5 V output.

The unit accepts an input voltage range from 2 VDC to 30 VDC and is capable of maintaining all outputs within specifications with input voltages as low as 2 VDC. That being said, the power supply will not start with initial input voltages less than 8 VDC. Three different outputs are available from this supply. The smallest is +5 VDC output. The other two are +24 VDC. One of these is +24VDC Relay power outputs, which supplies power Series 90-30 Output Relay module circuits. The last is Isolated +24 VDC. Typically, this power is used internally by some modules; however, it may also supply external power to 24 VDC Input modules.
 

Users can calculate the power needed for their applications whenever using this unit. To start, you must determine the total output power load for each individual module in the system. These specifications are available in the Installation Manual for the IC693 PLC series. Next, multiply the output power by 1.5. This will give you the input power value.

Then, divide the input power by the operating source voltage to calculate the input current requirement. When you want to know the maximum input current, it’s best to use the lowest measured input voltage (or else a good estimate!). When making this calculation, take into consideration the start-up surge current requirements. It’s also advised to permit a margin of 10-20% to allow for variations.
