Series TS 970 Automatic Transfer Switch

Thomson Power Systems Series TS 970 Automatic Transfer Switch, 100 – 1200 Amp, automatically switch between primary and backup power sources during outages ensuring constant power when faced with any interruption. 

Equipped with a power contractor switching unit and an advanced TSC 7320 controller, the TS970 can automatically initiate backup power and transition back to the main source when stability returns. From data centers to refineries, the TS970 empowers businesses to operate with resilience and confidence. All load transfer sequences are “Open Transition” with in-phase transfer detection, or with adjustable neutral position delay to ensure adequate voltage delay for preventing out of phase transfers. All TS 970 Transfer Switch models have been 3-cycle withstand current tested in accordance with UL 1008 & CSA 178. Additionally, they can withstand 6 times overload for 10 cycles.
