Thomson 800A TS 870 (#10707)

THOMSON POWER SYSTEMS TS 870 AUTOMATIC TRANSFER SWITCHES

Thomson Power Systems TS 870 Automatic Transfer Switches employ two mechanically interlocked power switching units with a microprocessor based controller to automatically start a generator and transfer system load to a generator supply 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-before make”) with adjustable neutral position delay to ensure adequate voltage decay for preventing out of phase transfers.

TS 870 Automatic Transfer Switches are certified to UL 1008 & CSA 178 Standards for use in Emergency Power System applications.

All TS 870 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 870 Automatic Transfer Switch is rated for 100% system load. The TS 870 design allows optional use of integral over current trip elements within the power switching units. All TS 870 Automatic Transfer Switches use a 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.
