PKDM300F Three phase rail type multi rate electricity meterDetailed product description：

The PKDM300F three-phase rail type multi rate energy meter is suitable for installation in compact energy metering cabinets or cabinets. It comes standard with an RS485 communication interface and is compatible with various configuration systems through the standard Modbus protocol. This enables real-time transmission of electrical parameters collected by the front-end to the system data center, facilitating automation management of electricity usage. The maximum current that can be directly connected is 100 amperes, and it can measure up to 8 time periods and 3 different rates of active energy in a day. At the same time, it can store the energy data of the past 3 months.
