MC 640 / MC 646 - Multifunction meter

MC_646_190.jpg

The MC640 / MC646 multifunction meter is intended for monitoring and measuring electrical quantities of a three-phase electric-energy distribution system. The meter is provided with 32 program adjustable alarms, up to four input or output modules and communication. With the RS 485 communication the meter can be set and measurements can be checked. The meter functions also as an energy meter, with the additional function of cost management by tariffs. A tariff input or a tariff clock can be set. At tariff clock setting, four periods and four work groups as well as electric energy price for each period and work groups (16 different price periods) are available. Additionally 20 places are available for setting holidays or days when special tariff rules are valid. As anenergy meter it records energy in all four quadrants and four tariffs.
