Three-phase electric energy meter HMM-1

portablewireless

HMM-1 is intended to measure the energy consumption of a plant in order to increase energy efficiency. The HMM-1 device is used for remote reading of the power consumption of a plant, via a GSM / GPRS network, using an application previously installed on a PC. The measurement functions are performed by a three-phase multifunctional counter and the GSM / GPRS module embedded in it. The voltage is output to the HMM-1 directly, and the current is supplied via the current transformers. For easier installation use split core transformers. By selecting a current transformer, the current measurement range (eg 400/5 A or 2.000 / 5 A) is changed, and then the meter is programmed, ie enter the data on the current transformer. Operation of the HMM-1 can be monitored on the built-in LCD with appropriate symbols.
