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. For more information on the products please refer to the corresponding tabs above. This web site also offers a general tutorial on all ratings and types of transfer switches which you will find very informative.
The TwinSource MagLatch™ RMATSs are a cost effective way to convert single corded IT loads to dual corded configuration so as to achieve the same availability as the dual corded loads. This product is available in all worldwide voltages and frequencies making it ideal for multinational operations worldwide.
TwinSource Dual Cord Converter DCC-II-RMSTS static transfer switches for critical IT applications. It utilizes the latest state-of-the-art, fault tolerant, patent pending logic topology which provides higher redundancy of critical components than other STS designs, with a first time ever predicted MTBF of over 50 million hours.
TwinSource Dual Cord Converter DCC-III-RMSTS static transfer switches for high power, 3 phase critical IT applications. This plug-in rack-mount IT static transfer switch (RMSTS) utilizes the latest state-of-the-art, fault tolerant, logic topology which provides higher redundancy of critical components than other STS designs, with a first time ever predicted MTBF of over 60 million hours
The patented MagLatch™ design makes use of dual coil magnetically latched relays, rather than standard single coil relays, to eliminate contact bounce and relay failures caused by their coils remaining continuously energized. Coils that remain energized can experience winding failures due to heat if they remain on for too long which is what happens in ATSs when they transfer or if the alternate source is selected as preferred. The dual coil feature enables fast electrically forced transfers in both directions vs. only in one direction.

Ideal if you don’t want to intrude into your already installed large 2N system on site or if you need protection for a smaller server room with some single cord loads. You can also use this as a standard packaged solution for all your data centers that have single corded loads. The 2N UPSs are 80KVA, 480V, 3ph, 3W + G In, 480V, 3ph, 3W + G Out and sit on each side of a lineup of 2 outer UPS Modules (and typically 10 min. batteries) and the inner enclosures that contain the step down (from 480 to 208/120) Input Sections A and B, the STS Section, and the Output Section.
Each cord is supported by a separate 2N. The description of the Mini-4N is exactly the same as one Mini-2N x 2 sets with UPS designations A, B, C, and D in a paired fashion (A & B + C & D). Each dual corded load gets a feed from Mini 2N 1 and another Mini-2N 2.
