TwinSource

TwinSource manufactures rack-mount automatic transfer switches in both solid state (single phase and three phase) and electromechanical (single phase) versions. The solid state or static DCC-II transfer switch has been our flagship product for over 10 years and is a two pole single phase device available in ratings of 30, 40, and 50A (10KW) in all... worldwide voltages and frequencies. A 3 phase, 4-wire, 4 pole version has just been introduced as well that comes in 208/120V (US Applications Only), 50A, 18KW for higher power 3 phase situations. 4 pole is necessary to also disconnect/reconnect the source neutrals in a transfer. The solid state or static DCC-III transfer switch is a four pole three phase device available in the rating of 50A @ 208/120 volts, (18KW), only for the North American market at this time with 230/400V version planned for later. 4th pole is necessary to disconnect & reconnect the source neutrals in a transfer. The electromechanical DCC-I units are available in a 24A rating in all worldwide voltages. These systems all operate on the basis of powering your critical load from a preferred source and in the event that source falls outside your pre-set specifications, then the system transfers the load to the alternate supply automatically. It does this quickly in less than 1/4 cycle for the SCR based system and in less than 1/2 cycle for the electromechanical version, all without any risk of dropping the load or cross connecting the sources. The Preferred Source can be selected by a simple push of a button, remotely through the RS 485 port, or through a settings selection. The TwinSource Rack Mount Static Transfer Switch is considered "Best in Class" among rackmounted automatic transfer switch products. It has a proven track record of over 60,000,000 hours on line without a load failure among its installed base worldwide. We have systems across the globe mostly populated in US, UK, Singapore, Korea, Hong Kong, Dubai, and other locations.Read More
