Product Description
BG-75-30A series amplifier: The design mentality is unique, use debugging nimble convenient, has high merits and so on target, redundant reliability, high stability, etc.
Characteristics:
First: The power source uses the high stable annular transformer not to use the damage rate very high switching power supply, has the overflow (into set from restores insurance, overflow automatic separation, after trouble shooting dose not need replacement self-recovery), to gard against the thunderstroke protection function.
Second: Uses may insert pulls out the type part to choose the outlet form, the outlet may need to dispose nimbly according to the user, reduces the skeleton line aperture, enhance the transmission system the performance index and the reliability.
Third: Unique inserts pulls out the the type duplex filter, inserts damages minimum, the frequency makes a sound, the belt external inhibition is high, the choice different frequency division way must replace the different duplex filter. The reservation two way amplifier upward module and the duplex filter, promote as the bidirection product are extremely convenient, but in the online promotion sets at the 0-20dB attenuator, the balancer, the debugging is convenient. The reverse transmission uses the special-purpose high efficiency module to enlarge, the biggest work increases 18dB. The rainproof cast-aluminium outer covering, radiates, the rainproof performance is good.
