Allen-Bradley 1797-PS2E power supply FLEX Ex product

The 1797-PS2E is a power supply for the FLEX Ex product series by Allen-Bradley/Rockwell Automation. Every safe system must have a reliable power supply component so it is essential to purchase the right product that would serve this purpose. This kind of power supply is intended for isolating any incoming power that is unsafe from the system that is being controlled. Then the attainable energy is limited to levels that are safe according to the IS. Every system should maintain a safe area and the number of 1797-PS2E power supplies that are needed depends on the configuration of the system and the modules that are used within the system. This FLEX Ex power supply has 24 Volts DC input connectors for a power source and a current consumption of 1.6 Amps. In addition to that, the 1797-PS2E has a 5% AC ripple and four channels with each channel generating 8.5 Watts of output power. The voltage range of this power supply is between 19 and 32 Volts.
