埼広エンジニヤリング List of Products and Services

We would like to introduce the products we handle and the development systems, etc. Starting with the "electricity meters" for ordinary weather resistance and indoor weather resistance, we also handle "automatic meter reading system equipment" and "multi-functional recorders" that embody the voices from the field. In addition, we are also developing "power-related systems" such as remote monitoring and control systems for distribution lines, as well as "automatic meter reading systems," "energy management systems," and "public test facilities for PLC equipment." 【Products We Handle (Partial)】 ■ Electricity Meters - U Meter lineup (ordinary weather-resistant type) - U Meter lineup (ordinary weather-resistant type with automatic meter reading support) - U Meter lineup (indoor weather-resistant type/space-saving type) *For more details, please download the PDF or feel free to contact us.

The "URY120-T1" is a relay unit that can control the opening and closing of large currents up to 120A by connecting to our electronic watt-hour meter rated for 120A. By combining it with an automatic meter reading system, remote control is possible, and since it has the same structure as a standard weather-resistant watt-hour meter, it can be used outdoors (within the rain line). It is connected to the load side of the watt-hour meter and can be installed in either a "horizontal arrangement" or a "stacked arrangement." In the case of a "stacked arrangement," an optional "bracket" is required. 【Features】 ■ Capable of controlling large currents up to 120A ■ Remote control possible when combined with an automatic meter reading system ■ Can be used outdoors (within the rain line) due to its identical structure to a standard weather-resistant watt-hour meter *For more details, please refer to the PDF materials or feel free to contact us.

• Power Monitoring Equipment

The "U Meter Series" from Seki Hiro Engineering is an electronic watt-hour meter equipped with a misconnection detection function. It has the same terminal arrangement as conventional induction types, allowing for the reuse of existing wiring. It complies with the Measurement Law and has obtained type approval from the Japan Electric Measuring Instruments Inspection Institute. Additionally, it supports bidirectional measurement, enabling the measurement of both forward and reverse flow with a single unit, and its separated terminal structure reduces the burden of replacement work. 【Features】 ■ Existing wiring can be reused (same terminal arrangement as conventional induction types) ■ Complies with the Measurement Law and has obtained type approval from the Japan Electric Measuring Instruments Inspection Institute ■ Equipped with a misconnection detection function ■ Separated terminal structure reduces the burden of replacement work ■ Displays forward and reverse watt-hours cyclically (only for U23-T) *For more details, please refer to the PDF document or feel free to contact us.

• Power meter

This product is an electronic watt-hour meter (standard class, ordinary weather-resistant type, surface-mounted type, bidirectional measurement, with a transmission device) that complies with the Measurement Act and has obtained type approval from the Japan Electric Measuring Instruments Inspection Institute. It has the same terminal arrangement as conventional induction types, allowing existing wiring to be reused. It is equipped with a function to distinguish incorrect connections. Only the "U22-TS2/U32-TS2" supports bidirectional measurement, while the "U22-TS2r/U32-TS2r" does not measure reverse current. 【Features】 ■ Existing wiring can be reused (the terminal arrangement is the same as conventional induction types) ■ Complies with the Measurement Act and has obtained type approval from the Japan Electric Measuring Instruments Inspection Institute ■ Supports bidirectional measurement, allowing both forward and reverse directions to be measured with one unit ■ Equipped with a transmission device (no-voltage contact) ■ Includes a function to distinguish incorrect connections *For more details, please refer to the PDF document or feel free to contact us.

The "MFR100W" is a recording device with a variety of measurement functions that can be wirelessly operated via radio. Its compact design, about the size of a palm and weighing approximately 220g, allows for flexible placement.

• Recorders

The "HD-PLC compatible PLC modem" is a product that utilizes existing power lines, enabling network construction with minimal wiring and ease of setup. It adopts a coupler connection, allowing installation and inspection without cutting off electricity. It experiences fewer transmission volume reductions and transmission downtime due to propagation obstacles, and it can be installed at a lower cost compared to conventional wired transmission methods. 【Features】 ■ Resistant to interference and has high robustness ■ Wide voltage adaptability, compatible with 400V systems used in factories, etc. ■ Capable of supporting multiple cameras on the same line *For more details, please refer to the documentation. Feel free to contact us with any inquiries.

• LAN construction and wiring work

The operator can obtain the display information necessary for instrument replacement without taking their eyes off the instrument terminal section.

• Other electronic measuring instruments

We have posted the drawings of the PLC master unit, slave unit, and phase coupler.

• Power meter

The distribution line remote monitoring and control system connects a "substation" installed on a pole with a "main station" installed on-site via communication lines (metallic/optical) to perform monitoring and control of the distribution line (such as monitoring the status of circuit breakers and control of switching on and off).

• Power meter

By installing our "U Meter + Control BOX" from the existing meter, it will be possible to remotely "stop the supply of electricity" using a mobile network.

• Other services

The automatic meter reading system is implemented not only for bulk electricity suppliers but also for small-scale properties. Since all products, from the electricity meter to the monitoring app, are in-house, we respond flexibly to our customers' needs. This system uses power line communication (PLC method), where the PLC master unit collects 30-minute values from each electricity meter and transfers the data to the reading terminal via mobile routers and other devices.
