CHAS-2® Amplifier and Power Supply Modules

At the heart of the CHAS-2 Headend Amplifier System is the CHAS-2 Headend Amplifier Module. The amplifiers feature separate RF and DC compartments for maximum EMI shielding, as well as large vertical fins that dissipate heat efficiently, eliminating the need for cooling fans. All amplifiers are 1 GHz and have four (4) ports: signal input, signal output, input test and output test point. They feature continuous slope and gain controls and allow adjustments without service interruption. All modules are hot swappable... Click PDF for more

CHAS-2® Status Monitoring

CHAS2 Status Monitoring
There are two main options to monitor the CHAS2 Headend Amplifier System: Contact Closure and Web Based monitoring.
For those cable operators employing a proprietary monitoring system, the CHAS2 is available with a contact closure equipped chassis. The chassis incorporates an alarm interface that provides 8 individual dry contact closure alarms, each related to a specific slot in the chassis.
For Web Based monitoring, each chassis can be equipped with either a Master or Slave card. Each Master Card has a unique MAC address, and Internet interface (WEBSITE) allowing remote monitoring via web browser, allowing the CHAS2 to be seamlessly integrated into an overall LAN system. ... click PDF for more

CHAS-2® Dual Sense A/B Switch

CableServ has developed the CHAS2 Dual Sensing RF Redundant Transfer Switch as an additional component of the CHAS-2 Headend Amplifier System. Designed as a modular unit similar to the CHAS-2 Power Supply and Amplifier Modules, the RF Switch fits into any slot in the CHAS-2 Chassis. The CHAS-2 Dual Sensing A/B SWX is an RF power transfer design that will automatically switch between a Primary and Secondary RF source. Any two RF sources may be employed, as the RF Switch senses the average power of the Primary (A) source and transfers to the Secondary (B) source when the (A) source drops below a set threshold level. The RF Switch Primary (A) source is always directed to the Output even during a complete power loss to the RF Switch... click PDF for more
