Applications
Thomson Technology TS 870 Standard 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 retransferred 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 to prevent out of phase transfers.
