Tomada de passagem KATHREIN 3 vias DC passagem ESD 33 (211500013)

The KATHREIN ESD 33 is a three-way loop-through socket that passes DC power to the SAT output, allowing remote-powered satellite equipment to be connected without an additional power inserter. Its 10 dB tap loss on all three outputs balances signal levels across TV, radio and satellite, while the 1.5 dB through loss keeps the loop signal strong for downstream outlets.

Highlights

• Three outputs: TV (IEC male), Radio (IEC female), SAT (F-connector)
• DC pass-through on SAT output for remote powering
• Wide frequency coverage: 5–862 MHz for TV/Radio, 950–2200 MHz for SAT
• High shielding effectiveness: >85 dB per EN 50083-2
• Low through loss: 1.5 dB on all bands

In daily use

Install the ESD 33 in a standard flush-mounted box. Connect the incoming cable to the loop input F-connector, then run the loop output to the next socket. The three outputs provide simultaneous TV, radio and satellite signals. The DC pass-through on the SAT output powers devices like LNBs or multiswitches, simplifying installations where a separate power supply would otherwise be needed.
