Prometheus

• 2400 W PEP total rating of RF power transistors.
• Cool running 4800W Switching Power Supply (SPS4800) or Extra Heavy Duty DC Linear Power Supply (LPS4800) is the most powerful in the industry with 12 and 7 KVA peak ratings respectively.
• Fully Automatic Band Switching: The DX-2400L1can be controlled (optional converter may be required) with the transceivers band data through CAT/CIV/RS232 style optically isolated interface.
• For older transceivers without band data, the DX-2400L can sample the incoming RF drive and determine the proper band of operation under microprocessor supervision.
• Dual control inputs allow operation from two different radios.
• SO2R (Single Operator, 2 Radios) option.
• Four Position Antenna Switch with automatic memory for last antenna used for each band.
• Vacuum antenna relay as standard equipment. PIN diode T/R switch available as an option.
• Full Loop QSK Keying to interlock transceiver and amplifier.
• Digital Bargraph Display for Forward Power, Reflected Power and True (computed) SWR.
• Optically Isolated RS485 remote interface operating either full or half duplex allows operation up to 1500 feet away through one or two twisted cable pair with optional PC adapter and software package or optional remote control head.
• Optically isolated remote on capability from transceiver +12V Auxiliary jack.
• Full optic isolation of all control functions (Key In, Key Out, PTT, Band Data, Remote On) from transceiver as well as full isolation of computer /remote interface port.
• ALC: Negative going from 0 to -10 Volts, adjustable. SWR-ALC foldback protection.
• Protection circuits: SWR overprotection circuit. Over temperature warning and shutdown protection. Over / under voltage lockout protection. Overdrive protection. Hardware failure protection (combiner balance, PIN T/R failure)
• FLASH Microprocessor allows field upgrades of amplifier firmware.
• Separate low voltage control transformer for bias and microprocessor circuits reduces power consumption in continuous standby mode and allows metering of transceiver when in bypass mode. 
• Low Pass Filters constructed with 12 gage coils and custom high power capacitors.
• Oversize (30 lb) heat exchanger and 4 thermostatically controlled, ball bearing, variable speed cooling fans mounted in push–pull configuration for redundancy.
• Sturdy, 1/8” thick extruded aluminum cabinet with precision laser machined 1/8” thick chassis, front and rear panels finished with textured black paint over yellow irridite finish.
• Hardware interface for support of optional antenna tuner.
• Optional Rack mount package.
• 1 Year Warranty on Parts and Labor, excluding RF transistors. Extended warranty available.

LPS4800 Linear Power Supply Additional features:

• Microprocessor controlled soft start circuit.
• Oversize 70 lb. 7KVA peak, 5 KVA continuous rated self shielding toroid transformer with manufacturer's lifetime warranty is removable for UPS shipping.
• Oversize, 40 lb, self shielding, toroidal filter choke with manufacturer's lifetime warranty.
• 50,000 uF filter capacitance, stud mounted rectifiers on individual heat sinks with thermostatically controlled ball bearing cooling fan.
