Product description

House amplifiers (in text-amplifiers) are intended for amplifying and distributing TV signals in cable TV networks.

The amplifiers are produced with built-in power supply for powering from mains ~198…250V and for remote powering from line ~24...65V (depending on type). The amplifiers have one input and two outputs.

The amplifiers are provided for plug-in return path amplifier and interstage attenuator.

Plug-in return path modules are not included in a package.

 

Safety instructions

Installation of the amplifiers must be done according safety standards and by qualified service personal.

The amplifier HA803A-R is powered from mains~198…250V and HA803B-R- from line ~24…65V via input connector. In both cases voltage is dangerous to life.

Equipment of remote powering distribution amplifiers must have protection from short connection.

To avoid the electric shock follow these instructions:

do not remove the cover of the power supply section and amplifier, without isolating the unit from the mains supply;

do not plug the amplifier into the mains supply if the power cord or plug are damaged;

it is recommended do not plug the amplifier into the mains supply until all cables have been connected correctly;

do not put the vessels (like vases) with water or other liquids near the amplifier to avoid liquids spill inside.

Do not install the amplifier close to central heating radiators or other warmers and in areas of high humidity;

if the amplifier has been kept in cold conditions for a long time, keep it in a warm room no less than 2 hours before plugging into the mains supply;

do not cover the amplifier with foreign objects to ensure normal ventilation and avoid its overheating.
