Push-in connector switch can make work for rotary switch time in half
In recent years, wire termination technology has slowly migrated from traditional screw connectors to “screwless” terminations. This first appeared on simple DIN rail terminals, and then on other hardware, such as PLCs, relay sockets, etc. Initially, this screwless change was done wit...Read more -
Basic composition of switching power supply
1. Main circuit Impulse current limit: limit the impulse current on the input side when the power is turned on. Input filter: Its function is to filter the clutter that exists in the power grid and prevent the clutter generated by the machine from being fed back to the power grid. Rectification a...Read more
