Generator ATS Controller Automatic Transfer Switch Panel 63A 100A 125A 250A 630A 1000A ATS SLS3-125b

This changeover switch is an microprocessor based PC class device designed to transfer loads automatically and manually from one power source to another in a wide variety of 1-3 phase applications. The unit monitors 3-phase normal and reserve source voltages, sends remote start command to the generating set and performs changeover switching between those 2 sources connecting the load circuits to a power source having voltage and frequency within preset limits. Device has a manual load switch lever, a manual/auto mode switch and a mechanical locking switch. Inputs and outputs: fire linkage control, generator remote start, external indicators. The front panel leds provide information about mains and generator power availability as well as a current switch position. The device display control panel shows device current state and source voltages and frequences and can be placed on the switch front side or in a distance of 1-3 meters from the device via standard Ethernet cable. Power source voltage/frequency limits, transfer/start/stop delays, generator exerciser schedule and transfer modes are front panel configurable. Note: The delays apply in case if the device is connected to 24VDC auxiliary power supply only. Features • High density silver-alloy contacts providing thousands operating cycles at 100% rated load; • Bridge type double break design not requiring special SCPD and matching AC-33B requirements; • Optimized magnetic blow-out arc extinquish system allowing to reach 10le capacity; • Multi-mode operation including manual transfer, automatic transfer with/without autorecovery and generator control under various configuration settings; • 3 working positions: main power ON - backup power OFF; main power OFF - backup power ON; main and backup power OFF; • Microprocessor controlled operations; • Reliable mechanical interlock and electric interlock; • "Zero Position" technology. Device can be set to Zero Position under emergency situations with two way power supply cut off meeting the fire fighting linkage requirements; • Singleness motor drive providing smooth, reliable, low noise operation; • Driving motor energized during switching operations only and having outstanding energy saving; • Mechanical interlock, making sure that the Normal power and Reserve Power sources work without interference; • Distinct ON and OFF positions and activity indicators; • Electromechanical integration design with accurate changeover adopting an advanced logical control technology and high anti-interference ability; • Easy installation using control circuit plug type terminal connections.
