Electrical network prepayment energy control mechanism having central unit producing set frequency binary signals and frequency conversion interface energy threshold relay operating.

摘要

The prepayment energy control mechanism has a processing assembly commanding the opening of a relay (7,8) when a set energy consumption level is met. The relay is monostable and has a central unit (17) producing binary signals (A) at a predetermined frequency and a frequency conversion interface (18) connecting to the relay.
