Description
1
Support board for fixing the supply module directly onto the AM1-DE200 / DP200 DIN mounting track or the AM1-PA Telequick perforated board.
2
Display block with:
  • a 24 V LED (green): lit if the internal and output voltages are correct,
  • a LSH LED (orange) only on TSX SUP 1021 "power optimization mode": lit if the power supply is running in parallelization mode with power optimization.
3
Flap for protecting the terminal block.
4
Screw terminal block for connection:
  • to the AC/DC supply network,
  • to 24 VDC output.
5
Hole for the cable-tightening clip to go through.
6
110/220 V voltage selector. On delivery, the selector is set at 220.
7
"NOR/LSH" switch placed at the back of the module to control the power optimization system. This switch is only present on the TSX SUP 1021 module.
  • NOR position: normal operation without power optimization (default position),
  • LSH position: operation with power optimization with supply running in parallel.
Note: Access to the switch requires the module to be removed from the support board.
