Thomson 600A TS 970 (#10891)

THOMSON POWER SYSTEMS TS 970 AUTOMATIC TRANSFER SWITCHES

Thomson Power Systems TS 970 Automatic Transfer Switches employ a power contactor switching unit and the TSC 7320 controller to automatically start a generator and transfer system load in the event of a utility supply failure. System load is then automatically re-transferred back to the utility supply following restoration of the utility power source to within normal operating limits. All load transfer sequences are “Open Transition” (i.e.“break-beforemake”) with in-phase transfer detection, or with adjustable neutral position delay to ensure adequate voltage decay for preventing out of phase transfers.

TS 970 Automatic Transfer Switches are certified to UL 1008 & CSA 178 Standards for use in Emergency Power System applications.

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. The standard TS 970 Automatic Transfer Switch is rated for 100% system load. All TS 970 Automatic Transfer Switch utilize the TSC 7320 microprocessor based controller which provides all necessary control functions for fully automatic operation. The controller is equipped with 2.3” back-lit LCD display which provides operating status and controls. All parameters and configurations are entered without opening the front door.
