This is the central supervisory control system we delivered to a waste disposal plant in Saitama prefecture 2013. This system monitors the condition of equipment in the plant and controls these equipment’s operation and speed. An operator station (personal computer), monitor panel (desk board), and a control board are installed in a central control room. All signals from the plant are collected to the center through control boards, remote boards, and network devices placed in each section, and are controlled by PLC. In the recycling section, systems are divided into the lines depend on the kind of garbage, and those lines are instructed by the operator station. Though the system performs automatically, operators in the central control room observe the video of monitor cameras and instruct watering, emergency stop, adjustment of speed on conveyor and so on, occasionally.

With liberalization of electricity and development of information and telecommunication, the trend has been changed from concentrated power supply to distributed power supply such as solar power and biomass power generation. In addition to energy saving, requests for securing business continuity has been increasing every year after the Great East Japan Earthquake. As symbolized with smart phone, cloud society where environment of internet connection at high speed and capacity, and large scale servers are indispensable has become a reality. Distribution system for IDC must be “design for failure”, that is an important concept in cloud. Avoiding all risks, such as power failure, higher harmonic interference and seismic hazard, power supply is required to work properly for 24 hours, 365 days.

Power distribution panels for severs are dedicated to supply electricity, which is provided from UPS to PDU, stably to server racks and meet the demand for the high quality. The feature performance of this product is that it prevents system failure with the structure correspond to the thermometry by a noncontact infrared thermostat sensor, optionally equipped with the multi meter plug-in MCCB-N phase strengthening MCCB with higher harmonic measurement function. Moreover, system failure can always be supervised with a load current measurement converter with a communication facility.

PDU is also dedicated to supply electricity, provided from UPS, stably to server racks with high quality. It’s feature performance is that it prevents system failure with the structure correspond to the thermometry by a noncontact infrared thermostat sensor, having a high-speed power supply transfer device, K factor transformer, and N phase strengthening MCCB as a standard specification. Moreover, an individual cover is attached to output TB to ensure the safety, work space is also secured to improve work efficiency.
