Precision distribution cabinet

Product features:

---The cabinet body adopts a standard 19 inch cabinet, and the interior adopts a modular design, which is neat and standardized. Adopting a single mesh door (glass door optional) design, intuitive and reliable. There are cable entry holes at the top and bottom of the cabinet, making it convenient to enter cables from the cable trough in the computer room or from the cable trench;

Up and down wiring methods for selection, front and rear door opening, front operation, cabinet rear wiring, maintenance and repair;

Reliable earthing system and overvoltage protection circuit are set in the cabinet to ensure the reliability of power supply, the stability of communication system and the safety of equipment;

The cabinet is equipped with dual inputs and dual bus outputs, with a maximum distribution of 54 channels x 2=108 channels, suitable for most computer rooms and can be customized according to user needs, such as single bus column cabinet;

The switch devices are all made of internationally renowned devices such as Schneider and ABB, which are safe and reliable;

The main switch adopts a fixed molded case circuit breaker, optional plug-in type, and the output adopts a regular miniature circuit breaker, or ABB hot plug miniature circuit breaker can be selected;

Both double busbars adopt C-level surge protection devices, effectively protecting the back-end core equipment;

Using a 7-inch touch screen to display the current, voltage, frequency, power and other electrical quantities of the dual AC power bus, as well as the feedback status and current, as well as the switch temperature, and uploading data from this cabinet through the RS-485 communication interface, achieving unified monitoring of multiple cabinets.
