OVERALL AMPLIFIER CHARACTERISTICS
Hardware and Software Protections • Over and Under Voltage DC, Over and Under Voltage AC, RF and Power Supply Temperature, RF Coaxial
Output Open or Short Circuit • Capability of a long working time on Short/Open loads at all phase angles without any damage. • Last generation 1400 W LDMOS, VSWR > 65:1 @ all Phase Angles, designed for enhanced ruggedness ISM applications and plasma generators. • Integrated AC Mains filtering. • Integrated lightning protection. • Delayed energized of the system after Mains Power Blackout prevents against peaks and high variation voltages typical of this events. • Soft controlled sequential start-up so to reduce the Inrush current during OFF to ON transition. WEB/SNMP Telemetry and Remote Control • Full Local or Remote control by by logon username and password. • Remote control with Smartphones or Tablet. • Host Logic and tele-measurement (TM, TC & TA). • Remote control and monitoring via SNMP and/or WEB interface. • With logbook or log file to record error or alarm message. • Display of forward/reflection power value and reflection high alarm. • TCP/IP, SNMP, GSM and PSTN TELEMETRY
Human Interface • Each module is equipped with a logic controller that allows full control by a local operator. • All transmitter and amplifier parameters required for diagnostics can be retrieved locally or remotely via standard (IP) protocol and standard software (web browser, SNMP). • Multilingual user guidance. • High Definition, high contrast Color Oled display. • Quick set of thresholds for protections level. This set is based on assignment of three “flavors” or PERSONALITIES: Conservative (primary target = protect itself), Standard (balanced), Aggressive (primary target = transmission without interruptions).
