We would like to introduce a case where a power company implemented a low-cost power visualization system to reduce our server update costs. The server update costs for the previously used system were enormous, making it difficult to continue the contract, so they were considering a successor system for the power visualization service. After implementation, while maintaining the configuration of the existing system, we designed and proposed a solution that utilized the battery-operated pulse measurement terminal "WLM-PC1" and "Mibunroku Cloud," ensuring that costs fit within the expected service fees. [Case Overview] ■ Previous Specification: Power visualization system using third-party cloud and servers ■ Challenge: Server update costs were enormous, making contract continuation difficult ■ Solution: Implementation of the battery-operated pulse measurement terminal "WLM-PC1" and "Mibunroku Cloud" ■ Customer Feedback: The ability to maintain operations similar to the existing system's configuration was highly valued ■ Implementation Effect: Reduction of initial and running costs *For more details, please feel free to contact us.

We would like to introduce a case where our power monitoring system was implemented by an environmental and energy consulting company. The in-house developed gateway and cloud system that were previously used had aged, and the other company's measuring devices that were being used were discontinued, necessitating the need for alternative products to handle new projects. After implementation, we applied our own power meters along with the "WGWB" and "Mibunroku Cloud" to new projects. In locations where existing products from other companies were installed, we successfully built a hybrid configuration, establishing a flexible monitoring system. [Case Overview] ■ Previous Specifications: Other company's power meters and in-house developed gateway/cloud system ■ Challenge: Need for alternatives due to aging and discontinuation ■ Solution: Introduction of multi-circuit power meters and IoT gateway "WGWB" ■ Customer Feedback: The flexibility to connect and integrate other company's devices into the same gateway was highly valued. *For more details, please feel free to contact us.

We would like to introduce a case where our manufacturing line equipment's idling power waste reduction and preventive maintenance system were implemented for a customer operating a factory. In the factory, there were various heat-generating furnaces, and wired connections led to significant cable degradation and wear due to heat, making data collection via wired methods difficult and resulting in individual management for each site. After implementation, we utilized the wireless capabilities of the IoT gateway to gradually start data collection from areas within range of the office. This allowed us to identify devices in idling states, contributing to the reduction of unnecessary power consumption. 【Case Summary】 ■ Previous Specification: Individual management of equipment power panel data for each site ■ Challenge: Desire to promote energy conservation and preventive maintenance ■ Solution: Implementation of IoT gateway and multi-circuit power meters ■ Customer Feedback: The ability to build a system wirelessly and cost-effectively in an environment where wired connections were difficult was highly valued. *For more details, please feel free to contact us.

After implementation, we provided a configuration where a SIM card is inserted into the "WGWB Web Logger Model," allowing remote access to download and collect measurement data, enabling the collection of necessary power data while remaining in the office. [Case Overview] ■ Conventional Specification: Installation of wireless loggers from other companies on-site with manual collection ■ Challenge: Desire to reduce the effort of data collection ■ Solution: Introduction of IoT gateway and multi-circuit power meters ■ Customer Feedback: The low-cost implementation and significant reduction in travel and movement labor were highly appreciated. *For more details, please feel free to contact us.

We would like to introduce a case where a manufacturer of multi-story parking lots has implemented our EV charging equipment's individual billing and remote monitoring system. Since the EV charging equipment is part of the common areas of the condominium, it was necessary to track who used how much electricity and bill them individually. However, the conventional equipment was discontinued, and a new system was required. After implementation, we proposed a configuration that collects data from multiple locations through the "Mibunroku Cloud" and stops charging when the current value falls below a certain threshold. This allows for the processing of usage statements to be submitted to facility managers, contributing to improved operational efficiency. [Case Overview] ■ Previous Specification: Old-type measuring terminal ■ Challenge: To remotely measure and centrally manage the electricity usage of EV charging equipment ■ Solution: Implementation of "Mibunroku Cloud," the wattmeter "WMS-PE2DO," and an IoT gateway ■ Customer Feedback: The ability to centrally manage multiple locations via the cloud was highly valued. *For more details, please feel free to contact us.
