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

The "URY120-T1" is a relay unit that can control the opening and closing of large currents up to 120A by connecting it 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 standard weather-resistant watt-hour meters, it can be used outdoors (within the rain line). It is connected on the load side of the watt-hour meter and can be installed in either "horizontal" or "stacked" configurations. In the case of "stacked" configuration, 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 the same structure as standard weather-resistant watt-hour meters *For more details, please refer to the PDF materials or feel free to contact us.

• Power and Energy 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 Meter Inspection Institute. Additionally, it supports bidirectional measurement, enabling the measurement of both forward and reverse flow with a single unit, while the separated structure of the terminal section 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 Meter Inspection Institute ■ Equipped with a misconnection detection function ■ Separated structure of the terminal section 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 materials or feel free to contact us.

• Other measuring instruments

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 detect incorrect connections. Only the "U22-TS2/U32-TS2" models support bidirectional measurement, while the "U22-TS2r/U32-TS2r" models do 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 measurement with a single unit ■ Equipped with a transmission device (no-voltage contact) ■ Includes a function to detect incorrect connections *For more details, please refer to the PDF document or feel free to contact us.

• Power distribution and control panels
• Electrical Equipment Testing

The automatic meter reading system is implemented not only for bulk electricity suppliers but also for small-scale properties. Since all products, from the power meters to the monitoring applications, 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 power meter and transfers the data to the reading terminal via mobile routers and other devices.
