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).
