Protection for Electrical Appliances like: Refrigerator, Freezer, Washing Machine, etc. Model AMT-R2
Introduction:
Whenever the electricity supply fails or there is a voltage fluctuation beyond the present acceptable limits, AMT-R2 disconnects the appliance from the mains, continues monitoring and the mains supply reconnected only when supply resumes and / or the voltage stabilizers within the limits.
As a further safeguard, the supply is only connected to the appliance when the voltage has remained within the limit for predetermined time normally three minutes. AMT-R2 has a fast response time within one cycle of less than 20% in which case AMT-R2 responds in about one second. This is important so that AMT-R2 will not disconnect as result of the initial voltage drop on the startup of appliances.
AMT-R2 safeguard the appliance from unstable operation of generator set due to its reaction to low frequency.
AMT-R2 has a built-in microprocessor, which adds an advanced feature of being a smart timer. Smart timer means that when the mains return to normal. AMT-R2 checks if the duration of the off time is more than 3 min. Then it will reconnect the mains after 30 sec rather than the standard 3min.
