DTZ541-ZDCL LoRaWAN three-phase current sensor
The mME (modern metering device) from Holley is a digital electricity meter. It can reflect actual energy consumption and usage time, and also visualize historical energy consumption values for the last 24 months.
Description
The Holley three-phase meter mME DTZ541 with LoRaWAN interface is a compact electricity meter for direct measurement of active energy in one energy direction in a 3 or 4-wire network. The product was developed especially for the nordic market. In addition to the indication by the display and the pulse LED, the consumption can also be transmitted via LoRaWAN. The meter can function as a class A or C device. The configuration is done by LoRaWAN downlink messages. In the standard configuration a measured value is formed every 15 minutes, thus a load profile can be formed if necessary. The meter complies with all standards to provide measured values for billing and is already in productive use in large numbers.
