Redundant L-Band multiple line amplifier

• The RAL-10 is a 19” Rack HOT SWAP EXTENDED L-BAND LINE AMPLIFIER, it allows to have up to 10 Amplifier Modules in a single chassis.
• The double redundant intelligent PSU technology allows an immediate switch on the secondary power source.
• The line Amplifier can be configurated with 1:1 or 4:1 redundant switching modules, that automatically switch the signal in case of fault.
• This technology ensures continuous quality of service and the hot swap Modules can be easily replaced by the local personal.
• An advanced monitoring system provides all measurements and alarms locally or remotely via WEB or SNMP.
• Ideal for Professional use, like Redundancy, Distribution & Monitoring, these are currently the best value for money.
