CATV Standard Two-way Amplifier

CATV  Standard Two-way Amplifier :

      HUASU two-way transferring amplifier series whose design is novel, debugging and using are convenient has characters of high-index, high-reliability and high-stability. High-efficiency switching power supply and high-stability linear power supply both are OK. The shell made by aluminum alloy die-casting is waterproof, shielding, and heat-resistant. Input and output both equip the ceramic discharge tube of high speed and heavy current. The series are optimized (a tractor serves several purposes) and intelligentized (only two points are adjustable) based on original equipment. Voltage of five-core plug-in is adjustable; branch and distribution are both in the equipment, which are handsome and convenient. Special adjustable inserted equalization is easy to upgrade and maintain, then the secondary equalization can be dispensed with and the consistency of bulk production is better. Short circuit plug-in is replaced by safety, power supply is protected twice, and amplification and network are safer.

The products are divided into: HSFB7230D single module economic type

                              HSFB 7230D double modules push-pull type
