Mains switching cards are designed for the installation in 19” 3U racks and serves three purposes:
- Mains switch: The mains switching card is able to switch a whole rack or parts of facilities on and off, with minimum wiring effort. A switch is placed on the front panel.
- Inrush current limiting: Many loads, such as power supplies cause a high inrush current at switch on time. When switching on several loads at the same time, the inrush current increases. The mains switching card limits the inrush current to a value that a customary B16A fuse will not break. There are no voltage losses or power dissipations in normal operation.
- Auxiliary voltages: The mains switch cards provide three potential free auxiliary voltages. The quality of the auxiliary voltages corresponds to the quality of our low emission power supplies.
CN0601 has a rocker switch, CN 0801 has a key-operated switch.
