Rb electronics designs and suppliesmanufactures and offes auotmatic mains failure controller units. [model amf-144 is one of the model of these failure controllers]. These controllers that are used to build diesel genset panels. The amf controller units have high-performance, single chip microcontroller that governs all the actions. Various technical features of these controllers are as follows:these units operating range is e from 10 v dc to 30 v dc, and thus can be used for 12 v and 24 v gensets. Inbuilt keypad unit has six keys on fecia that are used during the settings and during genset operation. Inbuilt led lamp indicators have three-phase indications for mains, genset and load side supplies. Flexible amf logics has inbuilt auto, manual and off modes. Full engine safety and lvm/gvm functions are available during manual mode. The units have lop, hct, v-belt, underspeed, overspeed, start failure, stop failure, fuel level alarm, fuel level trip, emergency stop and overload trip functions. Some of the aplications include:they can also be used for three-phase as well as single-phase applications. The circuit measures voltages of the three-phase mains input for operation within the set limits to decide the engine starting/stopping and for the mains contactor operation. This circuit measures the voltages of the three-phase genset input for operation within the set limits to decide the genset contactor operation. Using the key pad provided on the facia of the units many critical timers like mains failure, mains restoration, warm-up, mains-to-genset transfer, genset-to-mains transfer and cooling timers can be setng timers can be set using the key pad provided on the facia of the units. Four-digit 0.5" red display indicates engine speed, genset frequency and elapsed hour-minutes figure.
