AMF Controllers Overview

BeK3 & BeK3-zero AMF controllers

These AMF controllers are suitable for making AMF panels for industrial applications. The controllers allow setting up 3-phase Mains & Generator adjustable relays. You can monitor the earth fault current as well. The BeK3 AMF controllers in addition to the standard functions included in generator control systems feature a CANBUS & MODBUS serial interfaces. This will allow you connecting the most popular ECU available on the market. In case your engine is without 'ECU', you can connect to the BeK3 analog sensor to get a supreme protection ot the engine or you can use the cost effective BeK3-zero module. Expected life of the controller is about 20 years at ominal temperature of about 20 deg. Celsius.      READ MORE ABOUT BEK3 AMF ATS CONTROLLER

AMF + CANBUS + MODBUS + 128X64 DISPLAY + RS232 +32I/O. These are the most powerfull AMF controllers available on the market today. These AMF controllers are suitable for making high tech AMF panels for TELECOM applications. These controllers allow setting up a 3-phase Mains & Generator adjustable relay. You can monitor the earth fault current as well. These AMF controllers in addition to the standard functions included in generator control systems feature CANBUS,  MODBUS and RS232 serial interfaces. This will allow you connecting the most popular ECU available on the market. In case your engine is without 'ECU', you can connect to the Be2KP analog sensor to get a supreme protection ot the engine. This controller is designed for TELECOM BTS applications. The software automatically shuts down the display when not in use. This prolong the like of the controller fro about 25 years.    READ MORE ABOUT BE2KP AMF ATS CONTROLLER

In these videos you are going to see the main features of an AMF controller and how the AMF control panel works. There you are some specific examples. The AUTO mode operation may require some additional explanation. The Be142 AMF controller continuously monitors the status of the MAINS. The Be142 AMF controller allows you to set low/high limits for Mains Voltage and low/high limits for the Mains Frequency. In other words, when the voltage and the frequency are within the limits, the Be142 AMF controller transfers the load to the Mains. If the voltage drops below the lower limit (or rises above the high limit) or, if the frequency drops below its limit (or rises above its limit), the Be142 AMF controller will disable the Mains circuit breaker. This prevent, after a programmable delay, a severe damage to your load. So, we can say that Be142 AMF controller prevents, in the first place a damage to your systems. Then, if the failure persists for a long time (a programmable timer is available ranging from seconds up to hours) the Be142 AMF controller will take care to start you emergency generator. Once again the Be142 AMF controller does its business to check the quality of the generator voltage and frequency. Once detected that the parameters are within the programmed limits, the BE142 AMF controller will enable the generator circuit breaker. Now, in case of prolonged power outages, your load is safely supplied by your emergency generator. Be142  AMF controller as we understood before does not forget to pay attention to the Mains. So, when the Mains parameters will return within the programmed settings, the Be142 AMF controller will transfer the load to MAINS. This will happen after a delay that will ensure that the Mains is in stable conditions. Once your load is connected to the Mains, the engine will run for a programmable time (so called COOLING DOWN TIME) without load. After the cooling down time the engine will stop and the BE142 AMF controller (and consequently the AMF control panel) is ready for a new power outage.
