HY115 AMPLIFIER GAIN 28dB
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 amplierifers 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 HY115-4 is powered form mains ~198...250V and HY115-3 from line ~24...65V via input connector.
In both cases voltage is dangerous to life.
Equipment of remote powering distribution amplifiers must have prote ction from short connection.
To avoid the electric shock follow these instructions:
do not remove the cover of the power supply section and amplifier,without is olating the unit from the mains
supply.do not plug the amplifier into the mains supply if the mpower 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 noless than
2 hours before plugging into the mains supply;
do not coverthe amplifier with foreign objects to ensure normal ventilation and avoid its overheating

Power supply
The amplifier with remote power supply(HY115-3) is supplied with ~24...65V via coaxial cable to input of amplifier.
The voltage can be passed to output with a help of a swithch.
The amplifier powered form mains 230V(HY115-4) is factory mounted with the mains cable.

SCHEMATIC DIA GRAM

 * depends on return path module:passive RPxx-01 or active RAxx-01
** for amplifiers with return path -+1.0dB
*** when f ≥40MHz,return loss ≥ 14dB(40MHz)-1.5dB/octave
