CableServ CHAS® Headend Amplifier System Product Description CableServ’s CHAS® Headend Amplifier System has been designed with the flexibility, configurability and optimum density needed for a wide variety of applications in today’s expanding CATV Headend. The modular systems approach enables Headend Managers to mix and match power amplifier modules of different bandwidths and gains in a common rack mounted chassis. Hybrid equipped amplifier modules are constructed of solid aluminum extrusion specially engineered to provide high shielding, compactness, ease of installation and maintenance, and maximum heat dissipation without the need of cooling fans. The unique heat radiator design provides 18 square inches per Watt of dissipation ensuring that the amplifier circuitry remains reliably cooled even in a stacked rack configuration. Headend Power Amplifier Applications The amplifier chassis holds eight modules of any combination of Amplifier, Power Module or accessory module. The chassis mounts into standard 19” racking occupying only 3 Rack Units (5.25”), one of the most space efficient systems on the market today. Automatic power source redundancy is incorporated in the chassis design which offers a variety of powering options including -48 VDC (30-85VDC) and 85264 VAC 50/60Hz. An optional accessory +24 VDC Auxiliary Input Panel enables the use of backup power. EAS The CableServ CHAS® A/B SWX RF Redundant Transfer Switch is an available accessory for automatic RF power redundancy between two CHAS® amplifier modules or any two RF sources. CHAS® Amplifiers are available in bandwidths from 5 MHz through 862 MHz ensuring future network configuration flexibility. Hybrid technologies include Push-Pull, Power Double and GaAs, single and dual stage, in a variety of gains. Product Features • 3 RU rack mount chassis system holds up to eight Applications • Multi-purpose Amplifier to 862 MHz • Laser Driver Amplifier • Isolation Amplifier • Return Amplifier for all bandsplits • IF and Narrow Band Amplifier • • • • • • • modules; Amplifier, Power Supply or Accessory. -48VDC option and Redundant Powering with automatic diode switching. Convection cooled for reliability without fans. Bandwidths from 5 to 862 MHz. Easy access to Slope and Gain controls and -30dB test point. LED’s for power. Various gains and bandwidths available. Full 24 Month Limited Warranty. Product Specifications Product specifications are available for the following models which are produced in Power Doubled (PHD), PushPull (PP) and Gallium Arsenide (GaAs) technologies. Models are single (S) or dual (D) stage hybrid with specified bandwidth, technology and gain (dB) including 0 dB Isolation (I). Powering Options Amplifiers may be powered from chassis mounted Power Modules or from a separate master supply. Each chassis will accept multiple (redundant) Power Modules which are available in the following voltage input ranges: 85 - 264VAC for North American and European Mains Operation -48VDC for TELCO operation When any two or more power sources are connected or installed in a chassis, they automatically operate in a redundant mode. Diode switching ensures zero transfer time. The optional CHAS +24 VDC Auxiliary Input Panel enables the use of backup power.
