Discontinued SSB DCW 2004 B - SEQUENCER FOR 6m, 2m, 70cm & 23cm PRE-AMPLIFIERS

The SSB DCW 2004 B, allows safe control ( with Bias-T incl. ) for the SSB range of masthead pre-amplifiers via the coaxial cable as well as for delayed switching of HF-linear amplifiers.

The sequential operation of the DCW 2004 B avoids reliably damage to the pre-amplifier that may be caused by HF-spikes during switching. It offers 3 switching outputs in total, which have ascending delay times. So not only linear amplifiers but other devices, like transverters, can be switched on with defined times.

The DCW 2004 B is designed for the amplifiers MHP - R and SP series. The PTT switching input of the DCW 2004 B accepts a circuit against ground or against + 5 .. 12 V. The pre-amplifier and a linear amplifier (if used) can be switched on or off as required.

The HF-section of the DCW-2004 B offers a very low insertion loss and a high shielding Factor
