PRODUCT DESCRIPTION
Multichannel amplifiers SA91L, SA91DL are parts of medium or large SMATV networks.
SA91L is designed as a launch amplifier and usually is installed at the begining of network. Its main purposes are:
- to equilize the power of signals in different lines;
- to make amplitude pre-correction of signal for compensation its loss in network;
- to supply voltage to LNB converters and other network elements like interstage amplifiers SA91DL, MV series multiswitches,
terrestrial path amplifiers and so on.
Terrestrial TV input has LTE signal suppression filter
.
SA91DL is designed as interstage amplifier with remote powering. Generally it is installed inside cascaded type networks
to compensate signal loss in trunk lines. It could be used as a launch amplifier if additional power supply is plugged to relative
connector.
The housing of amplifiers meets more stringent screening requirements according to EN50083-2, class A.
Suitable for moderate and tropical climates.
The amplifiers are intended for indoor use only.
SAFETY INSTRUCTIONS
Installation of the amplifiers must be done according IEC60728-11 and national safety standards.
Amplifier SA91L is powered from mains 230 V~ (this voltage is dangerous to life) and SA91DL - from line 12...20 V DC
through input connectors or auxiliary DC input.
Any repairs must be done by a qualified personnel.
Amplifier SA91L is double isolated from mains 230 V~.
To avoid the electric shock follow these instructions:
Do not remove the cover of the power supply section, without disconnecting the amplifier from the mains supply.
Do not plug the amplifier into the mains supply if the power cord or plug is damaged.
Do not plug the amplifier SA91L into the mains supply until all cables have been connected correctly.
To disconnect the amplifier SA91L completely - disconnect plug from the mains socket.
The mains socket must be easily accessible.
To disconnect the amplifier SA91DL completely from supply voltage, disconnect the cable from input connector.
The amplifiers shall not be exposed to dripping or splashing water and no objects filled with liquids, such as vases, shall
be placed on it.
Avoid placing amplifier next to central heating components, near highly combustible materials and in areas of high humidity.
No naked flame sources, such as lighted candles, should be placed on amplifiers.
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.
Do not insert any objects into ventilation openings.
The ventilation should not be impeded by covering the ventilation openings with items, such as newspapers, table-cloths,
curtains.
Mount the amplifier on not flammable wall or in not flammable installation box in vertical position (SA91L) with power supply
unit on the right side.
From top, front and bottom of installed amplifier must be at least 10 cm free space.
