1. Function: The switching power supply can convert the input AC power in the industrial automation control into stable DC voltage and supply it to the equipment and system, which brings convenience to the industrial control system. 2. Material: It adopts flame retardant PC material on the whole body and hollow design, which accelerates heat dissipation. The transformer of the switching power supply is all copper, which is highly conductive and not easy to heat. Long-term operation, to protect the internal components of the switching power supply. 3. Protection: The railway industrial power supply has overvoltage protection, overload protection, overcurrent protection, short circuit protection, etc. The indicator light of the switch can display the power-on status, and you can visually observe the operation of the switch. 4. Rail design: simple installation, compact structure, convenient and practical, can be directly mounted on the DIN rail. Closed design, contact protection screw connection, universal input. 5. Application: The rail power switch is used in industrial automation control systems, distribution boxes, instruments, communication equipment and other fields to protect industrial control equipment.
