Flexiva HPX™

TỔNG QUAN

The Flexiva HPX high-power FM transmitters feature:

• Fully integrated RF and control interface with FlexStar® exciters
• The FlexStar HDX exciter is the source of both the HD Radio signal and the conventional analog FM signal — in a single unit. This exciter creates a hybrid signal ready for amplification by the transmitter
• High-voltage power supply can be remotely located from the transmitter to fit even the tightest transmitter sites
• Basic transmitter controller provides critical life support, control, automatic exciter switching and diagnostic functions on MIMIC panel without reliance on a microprocessor
• Advanced transmitter controller option combines basic controller functionality and life support with a microprocessor and ¼ VGA GUI for advanced control and diagnostics including TCP/IP connectivity, WEB remote control and monitoring, and SNMP communications
• IPA stage uses the field-proven Z/ZX® hot-pluggable PA modules and power supplies with the option for redundancy
• ¼ wave grounded cathode design offers stability and efficiency
• Ability to bypass PA stage using Flexpatch to put exciter and/or IPA directly to air, with blower shut down. No user safety issues while servicing PA cavity
• Backed by broadcasting’s most extensive factory support, including 24-hour technical assistance, around-the-clock parts and comprehensive training

System

• High-power FM/FM+HD tube-based transmitter with nominal nameplate (FM) power output rating based on three models of 20 kW, 30 kW and 40 kW

Mechanical

• Solid, welded-steel exterior cabinets; aluminum inner skins and chassis
• Hinged rear doors for normal access, easily removed for maintenance or installation activities
• Major access panels are securely latched with a supplied hex head tool for quick, safe access
• Top- or bottom-entry locations for all cabling

Cooling

• Direct drive 3-phase blower in main PA cabinet
• High-efficiency flushing fans

RF Drive

• Requires only 30 W (analog) exciter
• Fully integrated RF and control interface with FlexStar exciters
• IPA stage uses the field-proven Z/ZX PA modules
  • Higher-power models employ two modules, providing redundancy
  • Lower-power system can employ optional main/backup IPA
• IPA modules are replaceable from the front of the transmitter

Power Amplifier Stage

• Common tube socket for all models; 4CX20,000C
• ¼ wave grounded cathode design offers stability and efficiency
• Ability to bypass PA stage using Flexpatch to put exciter and/or IPA directly to air, with blower shut down. No user safety issues while servicing PA cavity

Controller

• Basic transmitter controller provides critical life support, control, automatic exciter switching and diagnostic functions on MIMIC panel without reliance on a microprocessor
• Enhanced transmitter controller option combines the basic controller functionality and life support with a microprocessor and ¼ VGA GUI for advanced control and diagnostics including TCP/IP connectivity, WEB remote control and monitoring, and SNMP communications
• Four large front-panel analog meters: Forward/Reflected power, PA volts, PA amps and multimeter for other operating parameters

Power Supplies

• High-voltage, 3-phase linear supply with primary/secondary MOV protection; half tap on transformer and multiple voltage taps; some model upgrades may be accomplished with only change in HV transformer
• Rugged, reliable mains transformer provides worry-free performance, easy to tap for specific installation requirements
• Low-voltage control and IPA use switching supplies from field-proven ZX products, reducing spare parts costs
