3. Cooling System
4. Controller of the rectifier system:
MC2600 is the new generation DC power controller developed by
MEGMEET. It offers many features and functions, and a more robust,
user-friendly, and easy-to-use interface. A power monitoring system
is formed by this monitoring module together with Megmeet’s
rectifier modules, solar modules and distribution plug-in frame (or
distribution cabinet), realizing interactive operations in
human-machine interfaces, monitoring of system operating state,
intelligent battery management, and automatic energy-saving
management. MC2600 controller provides several communication
interfaces, such as CAN, RS485, Ethernet and dry contacts. The
RS485 and Ethernet ports provide flexible extension function and
parameters setting, firmware and logs downloading/uploading, remote
monitor system accessing, and it can realize remote monitoring.
MC2600 can be used as either separate system or hybrid power system
of rectifier modules and solar modules.
5. System Composition:
MC2600 controller together with rectifier modules, solar modules,
diesel generators, distribution plug-in frame (or
distribution cabinet) and other devices, forms a communication
power monitoring system. Fig. 1-1 shows the system monitoring
solution.
6. IVS(Intelligent Ventilation System) Working Principle:
The system is an intelligent ventilation system providing air
circulation, air filtration and cooling control for telecom room.
The system itself doesn’t include any cooling element. It directly
draws cold air into the telecom room from outside and exhaust hot
air from telecom room to the outside to realize natural cooling.
The system can be used standalone or integrated with air
conditioner cooling device.
Technical Parameters
Power Supply: DC48V;
Current: 1A;
Air Volume: 560CFM;
Noise: ≤55dB;
Application: applicable for various types of cabinets.
