Single-Phase Prepayment DIN Rail Meter
Suitable for a wide range of submetering and energy monitoring applications, including rental housing, industrial parks, leased factories, universities, employee dormitories, commercial complexes, retail stores and market stalls.
DDSU2591
The single-phase direct-connected smart energy meter is a new DIN-rail-mounted smart meter developed using advanced large-scale integrated circuits and IoT technologies, in line with current product development trends. It complies with GB/T 17215.211 and GB/T 17215.321 standards and supports Class B accuracy for active energy.
The meter is equipped with one RS485 communication interface and can optionally support one IoT communication interface, including but not limited to 2G, 4G and Wi-Fi. It is suitable for installations with limited space and can also directly replace existing DIN-rail or wall-mounted meters of the same specification.
