GR04190 AIR FILTER KIT
Integration and important Operating instructions
Ordering informations
The AU301-DP is designed for operation up to 430Wrms (DVB signal) with very high linearity, and TV
Analog Signal up to 1400 Watt peak synk, in common amplification, dual sound.
This design uses 6th generation family LDMOS devices that are capable of very high peak power as
long as the average power does not exceed specified ratings. The devices are protected by an
internal circuit, for Overdrive and high Mismatch load.
However is mandatory to handle with care the Input level during the "precorrection operations" due to
possible very fast and high spikes coming from the source.
The AU301-DP must allow the nominal voltage before applying RF driver signal or damage can result
to the amplifier. For this reason the voltage must be applied before the RF driver signal. Additionally,
the input signal, must be removed before powering down to prevent damage to the amplifier. You can
accomplish this by removing the RF driver signal and powering down the power amplifier.
The AU301-DP has not the internal Power Supply. It must be supplied by an external Power Supply
following the P.S. supply indicated on this document.
RES-Ingenium can provide two kinds of Power Supply:
- PS200 series equipped with 1 kW slots
- PS200-D3 @ 43 Volt (equipped with 3 Slots) for any Digital Operations
- PS200-D6 @ 43 Volt (equipped with 6 Slots) for any TV Analog Operations and CW
- Compact 43Volt / 4kW Power Supply (19 Inch, 2 HE) for any operation
In case of installation in a site with no air filter is strongly reccomended to buy the "Air Filter Kit
Accessory" coeded as GR04190 easy to install on the front panel.
When the AU301-DP in installed in a 19 Inch std Rack is important to leave a right space on the rear
zone to facilitate the exhausted air extraction.
It's suggested to leave one free unit (1 HE) at the top of the Amplifier.
In case of use of more AU301-DP in parallel an appropriate power combiner has to be used. The
connection between the Amplifiers and Power Combiner Input Ports is strongly reccomended to
use"low Loss Cables" type.
The Amplifier is equipped with an RF Monitor Output available by a SMA connector where is possible
to test the performances when the it's on duty. The RF Monitor Output is normally > -40 dB referred to
the main output in order to have a right signal managed by std Instrumentation.
Anyway a SMA pad can be put in series to reuduce the RF monitor amplitude.
The Amplifier is delivered in cartoon box packaging. Use all professional caution during unpacking,
handling and mounting.
Please consult RES-INGENIUM factory with any integration questions.
