Siemens Power Supply, Rack Mounting, 120 to 230V AC/DC Supply Voltage - SIMATIC Series - 6ES7407-0KA02-0AA0
Get your control-system modules up and running with this Siemens power supply. The unit converts input voltages to 5 and 24V DC loads, adjusting mains supplies to work with your system in a flash. With its short-circuit protection, the device cuts power faults off as they pop up to reduce the risk of hardware damage. Mounting the module takes no time as it slips onto a standard rack (such as 226-3954). LED indicators are on duty to show input and fault status at a glance, making inspections hassle-free. Power supplies like this are essential bits of kit in food production lines and fluid management systems.
