The ATS-125A-4P-iRC is an intelligent microprocessor-based device designed for automatic and manual load transfer from one power source to another in a wide range of 1-3 phase applications. The device monitors the 3-phase normal and standby source voltages, sends a remote start command to the generator set and performs switching between these 2 sources, connecting the load circuits to a power source with voltage within the specified limits. The device has a manual load transfer lever, a manual/automatic mode switch and a mechanical interlock. Inputs and outputs: fire control, remote generator start, external indicators. LEDs on the front panel provide information about the presence of the mains and generator, as well as the position of the current switch. An external display shows phase voltages and can be placed at a distance of 1-3 meters from the device using a standard Ethernet cable. Source voltage limitation Power, transmission delays, start and stop, and transmission modes can be configured on the front panel. Note: Delays only apply if the device is connected to an additional 24 VDC power source.

Features• 3 working positions: main power ON - backup power OFF; main power OFF - backup power ON; main and backup power off;• double folding contacts/ horizontal pull mechanism/ micromotor pre-energy storage and microcomputer control technology;• reliable mechanical and electrical interlocking;• "Zero position" technology. The device can be set to the zero position in emergency situations with two-way power cut-off, meeting the requirements of fire communication;• single motor, ensuring smooth, reliable, low-noise operation;• drive motor energized only during switching with extreme energy saving;• mechanical interlock, ensuring smooth operation of normal and backup power sources;• clear ON and OFF position and activity indicators;• high safety and reliability with a service life of more than 8000 times;• electromechanical integration design with precise switching using advanced logic control technology and high anti-interference ability;• easy installation with control circuit terminal connections.
