summary:

The DDSF601 single-phase electronic multi rate energy meter is an energy meter developed by our company using advanced international microelectronics technology and produced using modern production processes such as SMT wave soldering. The DDSF601 single-phase electronic multi rate energy meter can record the electricity consumed by users in different time periods according to the set multiple rate parameters. The meter can be set and read/written locally or remotely through an infrared programmer or RS485 interface, and long-distance electricity parameter collection can be established through the RS485 data network; Users can display relevant parameters in the electricity meter through the LCD screen. Electric energy meters have high measurement accuracy, high stability, and strong overload capacity. Long term use is safe and reliable, adaptable to a wide range of temperature environments, and easy to install. The use of LCD indicators for cumulative electricity consumption is particularly suitable for residential and industrial users for energy metering.
