How To Measure Your Bust

With your arms relaxed at your sides, measure around the fullest part of your chest.

How To Measure Your Waist

Measure around the narrowest part of your natural waist, generally around the belly button. To ensure a comfortable fit, keep one finger between the measuring tape and your body.

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).
