Product Introduction

The precision column head cabinet is based on HMI as the core and uses a modular structure of RS485 bus to effectively control the power microenvironment of the column head cabinet. The cabinet is equipped with a full power detection module, a branch current measurement module, and a switch quantity module. The modules measure the full power of the total incoming line of the column head cabinet, including three-phase current and voltage, active and reactive power, frequency, power factor, and electric degree. The current and switch status of each branch are measured, and the electric quantity of each branch is calculated through HMI, and an on-site monitoring interface is generated.

PRODUCT FUNCTION

Adopting a standard 19 inch cabinet body, the interior adopts a modular design, neat and beautiful. The shell adopts a glass door (mesh door) design, which is intuitive and reliable. The top and bottom of the cabinet are both equipped with cable holes, allowing cables to enter from the cable duct in the computer room or from the cable trench.

Pre set various load capacity alarms, overload alarms, and overpressure alarms.

10 inch full-color touch screen displays and manages harmonic content, energy management, historical trends, current trends, voltage trends, and load curves.

Equipped with sound and light alarm and remote monitoring interface.

Surge protection, lightning protection (optional), overcurrent protection.

Local LCD display and panel style operation, convenient for real-time query and monitoring.

Equipped with intelligent monitoring function, compatible with various computer room monitoring systems.

Internal unified zero and ground bars can effectively ensure grounding.

Product features and technical parameters

Cabinet: The cabinet material is made of pot coated zinc plate or phosphating treated anti-corrosion coated steel plate, with a polyester epoxy powder anti-corrosion layer. The cabinet door adopts a dual structure, and a metal baffle is used inside the cabinet, leaving only the operating switch handle to prevent operators from directly contacting live exposed parts such as busbars, and to prevent foreign objects from coming into contact with electrical devices; The outer door of the cabinet adopts a metal mesh door, and the front door and left and right baffles can be flexibly disassembled to achieve front and side maintenance of the cabinet. Operations personnel do not need to open the front door (with a door lock) to observe the operation of the equipment. The cabinet can be wired up and down, and the back side can be wired.

Input circuit breaker: ABB Tmax series molded case circuit breaker with a breaking capacity of not less than 70kA, and ABBPR221DSo electronic release

Input busbar: The input busbar is three-phase five wire, and the busbar is made of high-purity, high conductivity oxygen free copper with a purity of not less than 99.95%; The insulation support for fixing the busbar adopts reliable products, which can withstand the impact of mechanical and thermal stresses generated by the rated short-time withstand current and rated peak withstand current of the device

Output terminal: All output wires use ABB pullback quick connect terminal blocks, and the cable size is not less than 6mm2

Lightning protection module: adopting 20KVA, with a response time of less than 20ns, it can achieve remote monitoring function. The lightning protection module can be plugged and replaced, and it is equipped with an instantaneous overcurrent thermal circuit breaker, capable of withstanding 10000 surge surges.

Product advantages

Reliability: All components are standardized and tested by the manufacturer.

Safety: The front and rear panels are isolated to prevent personnel from coming into contact with live parts.

Simplicity: Due to the use of prefabricated components, the design and installation are very simple.

Easy to manage: With a comprehensive monitoring system, data center managers can have real-time control over the operating status of equipment, making it convenient for management.

Scalability: Drawer style expansion without changing cable layout.

Cost saving and step-by-step implementation: Modular design with reserved expandable module slots for users to expand in the future. Customers can purchase corresponding modules in stages according to their actual needs to save costs.
