DescriptionHM 2006 device is designed for electrical power demand regulation of bigger consumers.Regulation is optimized according to defined curve and set regulation or technical maximum.If trend of average demand verges to exceed the set demand value, particular stages of

electrical loads are being disconnected. In the casethat the trend verges under the set level, controller isreconnecting disconnected circuits.

Controller has 5 inputs, which are used for energymeter pulses of +P, +Q, -P, -Q and synchronizationimpulse. One input can be used for tariff indication.Controller is normally connected to the energy meterpulse outputs via separation unit. Controller outputs

are realized by 6 changeover contacts 3A/250VAC which control mechanical contactorcircuits of defined electrical loads.

Operation principleHM 2006 controller regulates demand according to set maximal value of average hour demand in kW. This value is periodically compared withmeasured power demand during the quarter-hour and in the case of fast power demand increase over the defined neutral zone, controller starts todisconnect appropriate loads.

If the power demand decreases under the certain level and power demand reserve appears,controller starts to connect appropriate loads back to the system.

Device shows, during quarter-hour period, calculation of the average hour power demandin kW according to the real power demand. After incoming of the pulse for the newquarter-hour beginning, this value is being erased. All disconnected loads will beconnected back and new regulation cycle will start.

Maximum reached quarter-hour value of power, date and time of this event for every tariffseparately are recorded into internal memory. Those maximal values are accessible on thedevice display. History of every power demand curve during quarter-hour is saved to theinternal memory with capacity for 40 days of recording.
