AC coupler using Active Shielding from Synergistic Research, USA. The adhesive on the tape of the sheath has weakened, so it has been repaired with 3M's self-fusing tape just in case. A slight gap was also found on the outlet side of the AC coupler, so it was repaired in the same way. - Model Name: AC Coupler with Active Shielding - Cable Type: Shielded Cable - Color: White Thank you for viewing.
